Telescopic Sliding Gate Installation

Telescopic gates are designed to allow a sliding gate to take up less space to the side of the opening. This is ideal where a conventional sliding space will not work, as there is not enough space for the gate to slide into.

As you will see in the video below we have created a system which affords a 5500mm gate to slide into a space of only 3200mm.

Telescopic sliding gates work by individual sections of a gate that are linked together and overlap each other as the gate opens to cover a larger opening.

As with all any other type of automatic gates system there will always be a degree of customisation, so therefore many of the technical components will vary, the size, specification of materials and visual appearance will always be different from project to project to ensure the operational and aesthetic requirements of the site are fully met.

Technical factors that need to be considered are;  level of security, usage, safety, integrating access control system and combining this with aesthetics and ease of use.

Here are 3 advantages and disadvantages of a telescopic sliding gate system.

Advantages-

Space- A telescopic gate will open into a space smaller than the entrance to which it is positioned. This is idea when a conventional sliding gate does not have enough space or parking space is limited and swing gate will not work.

Speed- Telescopic gates move open and close very quickly. A lot of consideration needs to be paid towards gate safety (below).

Security- Another advantage of telescopic gates are that they move incredibly quickly and cannot be forced open without exceptional leverage.

Disadvantages-

Ground levels- An important consideration when deciding if a telescopic gate is suitable for the entrance is how the level the ground is, or can be made to be. As the system uses a track it is essential that the telescopic gate runs on a on level ground. We are currently working on a cantilevered telescopic gate system to overcome this issue and we will post updates when this has been mastered.

Safety- If not set up correctly telescopic gates have the potential very dangerous. We will not fit railheads (spikes) on the top of the gate- because the telescopic sliding gate effectively becomes a giant hedge trimmer! We will also need to sheet the gate, open bars are not recommend at all because any body part that comes between the bars will be harmed when opening. It is possible to have an open bar design with the use of laser safety curtain.

Costs- Telescopic Gates are technically very challenging, this is not job for your average gate installer. A lot of time needs to go into the design process and they twice as long to install due to nature of setting up the drive system, linkages, 2 x tracks and all the additional safety required. The system will also require an upgraded motor and will need regular maintenance as the tension cable will require adjustment. Ordinarily we build the system in our factory and test it, then disassemble and reassemble on a customers entrance. Due to the amount of work & material cost involved we do not install telescopic sliding gates for less than £15,000+ VAT

How much does it cost to automate existing gates?

Often clients underestimate the cost of automating an existing gate. They tell us they search on the internet for a cheap gate automation kit for £300 then look for an electrician from Check-a-Trade to fit it in a day, for a few hundred pounds… bingo problem solved! Not exactly….

Their gate system might last for a couple of weeks before it all goes wrong, they then call us to come and rip everything out to start again! In most cases, the electric gate system will not even be legal and worst case it is highly dangerous!

The gate automation kit price only makes up a percentage of the total cost and the cheapest kits are usually the most expensive in the long term.

Our underground gate automation installation prices start at £2,600 + VAT.

First and foremost, there are labour costs; we respect electricians greatly however the electrical elements are only part of the job. It takes at least 5 years’ practical experience to be a qualified gate engineer.

Any true gate engineer will have all of the following skills and experience-

  • Industry approved training course qualification pass (DHF, Gate Safe, Etc.)
  • System design knowledge and assessment
  • Awareness of Standards & Regulations
  • Health & Safety procedures and practices
  • Risk reviewing for safe system operation and advice
  • Fault finding and rectification skills
  • Electrical competency & regulations
  • Ground works
  • Civil & Structural engineering skills
  • Landscaping and Drainage experience
  • Light building & Building Regulations
  • Fabrication, Erection and Welding
  • Mechanical engineering skills
  • Mathematics i.e. gate geometry, weight calculations
  • Hydraulics & Pneumatic’s
  • Carpentry & Joinery
  • Qualified and certified by all major automation brands- BFT, CAME, FAAC, Nice, Beninca.
  • Wide knowledge of Industry products, procedures & best options
  • Commissioning procedures and system maintenance
  • Access control & telecommunications interface
  • Audio & video, CCTV
  • Associated products & services, lighting, alarms
  • Making good & decoration
  • Computer literacy
  • First aid
  • Customer liaison & training
  • Technical file creation & management
  • On top of all this- be respectful, happy, friendly and prepared to work outside in all 
weathers!

These requirements vary depending on the complexity of the project but all our gate engineers are trained and ready for anything- and as you can imagine gate engineers with these skills are hard to find and command good salaries.

It requires over £5,000 worth of specialist tools to carry out most gate installations. We are constantly buying tools due to the high demands placed on them working outside in all temperatures and conditions!

Before work is carried out legally the qualified gate installation company have to carry out a detailed risk assessment, point loading calculations and a execute a full site survey.

Next, the equipment must be purchased. Here follows a typical list of components/costs required to automate a gate (excluding the automation kit which can run in at over £1000 alone):

  • Electrical enclosure / Cabinet
  • Junction boxes
  • Adaptable conduit
  • Armoured termination glands
  • Cable cleats and ties
  • Safety edges, receiver- its worth noting in some cases (particularly electric sliding gates) the safety equipment costs to make the gates legally compliant can amount to more than the gate automation costs!
  • Direct burial data cable
  • SWA cable
 (armoured)
  • Flexible power cable
  • Concrete
  • Ballast
  • Sheet metal for modifications
  • Adjustable hinges
  • Gate stops
  • Ducting
  • Clips, bolts, fixings
  • Resin, Silicon, Grease
  • Disposable items such as welding rods, cutting disc’s and diamond blades.
  • Disposal of waste from site (skip on site)
  • Fuel to from site
  • Parking/Congestion charges
  • Allowance in cost for warranty return visits
  • Delivery charges.

All this is without standard business over heads such as insurance, office costs, rates, vehicles, tools, advertising, accreditation’s, transportation and admin, accounts and sales staff costs etc!

In most cases this type of work takes 2-3 days on site and requires 2 engineers as the gates have to be lifted. There is also a lot of time consuming off site work such as planning the installation, ordering the materials, client liaison and document control.

Once the installation has been completed, we then carry out extensive testing, we have to force test the gates and complete a technical file, CE Mark the gates and provide a 2 year warranty.

Only then are we happy to carry out a demonstration, handover, with controls, to the client.

We hope this goes a little way to explaining everything we need to do, The words ‘cheap’ and ‘electric gates’ have never been in the same sentence! However, if done well, automated gates will be convenient, secure, safe and well worth the investment.

Therefore, if Renzland Powergates Ltd are £2000 more than a jobbing electrician prepared to try his hand at electric gates, you can be sure you are getting £2,000+ more of a job.

Around the corner sliding gate | Unique electric gate solutions

Many clients, particularly in London want an electric gate system to secure their car and property but their driveway has limited space for access. Electric gates are not permitted to swing outwards towards a public highway and a standard sliding gate would require too much space to open, so often, the best solution can be found by installing a round the corner sliding gate.

Renzland Powergates Ltd can offer clients a custom made round the corner sliding gate system which affords clients benefit of excellent utilisation of space, increased security, not protruding over a property boundary line whilst enhancing the value and saleability of a property.

The round the corner gate will conveniently and quietly slide along the side of the boundary line not obscuring any valuable parking spaces. Safety is assured due to safety edges, sensors and light curtains. We would also recommend if the gate system is not linked to acces control should be operated on a hold to run basis. The round the corner sliding gates can be integrated to CCTV, lighting and access control system if needed.

We are able to offer clients a large range of finishes- both timber and metal gates that “bend” around corners, while ensuring they are aesthetically pleasing and affording prestige. We can also design and install matching round the corner garage doors for mews properties that want the look and feel of a standard swing garage door without the “commercial” look of a roller shutter.

If you are live in London, Surrey, Berkshire or the Southeast and have an awkward driveway with a door or gate and are looking for a stylish electric gates solution, we would love to hear from you.

Our expert team can work with garden designers, architects and specifiers to design a solution to almost any problem area. We can provide CAD drawing and visual rendering of the proposed driveway gates. We love the challenge of transforming awkward driveways into prestigious examples of style and quality when other gate installation companies have walked away and said it could not be done.

We also offer “pop up” gates which raise of out the ground via a multi staged hydraulic pumping system, telescopic sliding gates and even gates that raise into the air, we have over 30 years of experience on unique projects.

Electric Gates Essex

Here is a recent electric gate installation of a carriage driveway in Essex. Renzland Powergates Ltd enjoys unrivalled reputation throughout the South East for quality and precision in luxury gate making.

As the brick piers were already under construction by others – The larger (main) opening was almost 5000mm wide (the smaller 3500mm) therefore we had to formulate a design that worked equally well on both entrances and framed the brick piers without dominating them.

Designing gates that work well on piers that reduce in size is tricky due to side gaps being larger at the top than the bottom (bell core). Therefore David Viera- Project Director designed gates that offered both a horizontal bar so the gates would fully opening without touching the pier caps, and also rise in the middle creating a subtle curve which gave the whole entrance a nice balance and a striking visual identity. Attention to detail was placed on the hinge positions to avoid the stone work and the end scrolls were custom made to sit exactly within the curvature of the pier caps which also to the eye subtly reduced the side gap. Further subtle skillfully crafted details were designed into the gates such a shadow bar at the top of the gates, custom made finials and even the slam plate was reversed to give a better aesthetic balance from from the front our mission is to create a symphony of precision. 

The gates were hot zinc sprayed and powder coated in a special silk matt finish. Hydraulic underground motors were chosen due to there faster operating speed and more powerful capabilities. We design and build gate systems to last for 20 years +

Electric Gates Berkshire

After Electric Gates Berkshire

 Electric Gates Berkshire

Here is a recent installation for a multi user gate system in Ascot, Berkshire. The brief was to create an electric gate system which sympathetically blended in with the existing built environment whilst being well engineered for continuous usage.

The clients were unsure of the best way to build the entrance, so we came up with 2 suggestions-

  1.  Modifying the existing piers and build new piers
  2.  Removing existing piers and build new piers

Our design team took detailed dimensions and drafted both options on CAD which you can view below- option one was chosen as aesthetically the entrance looked more balanced with a narrower driveway and the additional 1000mm distorted the gate. This is where Renzland gates drive real value in to the project, very few Gate installation companies in Berkshire offer this level of detail and design consultancy expertise pre-build. This affords our clients complete piece of mind knowing exactly what they are getting for their money.

Due to constant use the gate motors needed to be heavy duty and very reliable therefore BFT SUB BT motors were chosen as they are a low voltage hydraulic operator built for very intensive use, suitable for any type of residential, industrial or multi-residence application. The motors are fitted with mechanical stops which eliminate the need for a physical gate stop which has been known to damage low suspension sports cars. The motors have a built in virtual encoder, guaranteeing maximum anti-crushing safety thanks to the electronic slowdown.

As there were several properties using this gated entrance we advised the client on a GSM based intercom. This is a wireless entry phone system which avoided any issues and saved the cost of taking up the brick driveway for cable runs and making good internally to the house.  The system was mounted on a matching podium so visitors do not need to exit the vehicle.

The gates were hung from 2 substantial steel I beams (RSJ’s) located inside the piers they are then filled with concrete. This requires very precise setting out of the steelwork and onsite fabrication to ensure the gates align perfectly.

In our professional opinion this is the most secure way to hang gates on this type of application. Due to a sharp decline on the camber of the driveway to one side, the gates had a subtle infill at the bottom to make the gap less obvious. The gates are galvanised to BS EN ISO 1461 and powder coated to BS EN 13438 and BS EN 15773.

As you will see from the CAD visuals, this project was executed to the exact spec with the exception of the lights which were chosen and retro fitted by the client.

Which access control system is right for you?

Electric gates Access Control Intercom Articulated Arm Operators

 

We have all been disturbed early in the morning by annoying door to door sales people or others making unsolicited visits. The installation of an intercom system integrated within your electric gates means that you have control over exactly who can, or cannot enter your property.

With a vast choice of access control systems available- which system is right for you?

There are many variables to take into consideration and your choice will be limited by the range (distance from the door station at your gate to your home) environment, your requirements and of course budget.

Gate access control equipment generally fall into the following categories-

Hard wired Access Control- audio only-  Average cost inc fitting £350 + 

Pro’s- Offer a low cost, robust solution , no ongoing costs.

Con’s- Basic functionality audio only, cost of wiring into existing home and making good. Unable to control entrance whilst away from the property. The entry level models generally look and feel low end, which will detract from the entrance aesthetics.

Wireless Audio Access Control – Average cost inc fitting £450+ 

Pro’s Low cost, robust solution, no internal wiring or making good. Easy to expand the system. Portable can take handset into different rooms and garden.  Secure encoded radio transmission based on the use of rolling code. Can be removed and re installed if you move home.

Cons- Signal can be limited by line of sight, weather and atmospheric  conditions. You are unable to control entrance whilst away from the property,

*Visual wireless also available at addtional cost.

GSM Based Access control Systems – Average cost inc fitting £900 + 

Pro’s Control your entrance from anywhere in the world. No internal wiring your land line phones are usually already  in the most convenient place. Saves additional cost of remote controls. Increased security as caller will not be aware if you are home or not. Call can be diverted to multiple owners. Accept deliveries when not home. Programming, Faults and diagnostics available remotely reducing engineer visits.

Con’s- No Visual without additional wiring. Will not work if the telephone network down or poor signal area. Ongoing costs to top up PAYG sim card- this will vary depending on how popular you are! It is more difficult to control exit of the building without additional equipment. More expensive than wireless Audio entry control systems.

Hardwired Audio/Visual Access Control – Average cost inc fitting £1,000 + 

Pro’s- Visual and Audio- depending on the grade of equipment very high quality HD video is available. Record-able video available. Monitors can be in interfaced with additional CCTV around your home or other types of home automation systems such as crestron or control 4. Entrance visual monitoring.

Con’s- Night time visuals are poor unless a top of the range model chosen. More expensive than previously mentioned systems due to additional wiring and making good internally. Unlike GSM based systems you are unable to control the access when not at home.

IP Based Access Control Systems- Average Cost inc fitting £3,000 + 

Pro’s the best of all worlds- due to IP integration allows main performances such as access control, monitoring, image and video recording from control points internally and on any other smart mobile device- iPhone, tablet, laptop etc therefore you could be on a beach in Rio and see who is at your gate using your smart phone. Wiring savings as system commissioned by a unique network cable. Full integration of other home automation systems. Simply put there is no better.

Con’s- This is the most expensive type of access control system. Technology not yet mainstream therefore limited amount of professionally trained installers.

It is important to bear in mind that if you are looking to save money buying less expensive hard wired systems, you will need to factor in additional labour costs for cable runs and making good to the decoration to your home. In addition we would strongly recommend using high quality shielded CAT 6 cable duct grade that has a heavy black polyethylene sheath and a flame retardant PVC inner. Cat 6 offers high speed data transfers where underground duct or a weatherproof cabling solution is needed and the additional shielding is recommended if it is run close to power cables- we would always look to avoid running power and data cables in the same duct to reduce interference.

Unlike the movies, the access control panels cannot be blasted by a gun and then your gates will automatically open- however we would recommend installing vandal resistant product should your entrance be located with a large pedestrian footfall and especially youths loitering.

The aspect most people do not consider is exit control- how will people leave your property? Whilst the majority of electric gate systems are fitted with an exit vehicle loop- this will not benefit pedestrians. Push to exit buttons can be installed on timers so they only work during pre-determined hours, therefore on multi-user entrances where possible, it is advisable to have a separate dedicated pedestrian entrance.

For clients looking for an ultra secure controlled entrance, we can also install car number plate readers ANPR Cameras, bio-metric finger readers or even facial recognition- just ask we can help plan and deliver your perfect entrance- and perhaps even afford you a well deserved lay in on a Sunday morning ;o)

The differences between “mild steel” and “wrought iron” driveway gates

Be warned!

Many Gate Automation companies are selling mild steel gates as “wrought iron” as most clients do not fully understand what this means. This could be a very costly mistake especially comparing like for like quotations.

To the untrained eye there is little visible difference between forged bars of wrought iron & Mild Steel- the difference however are worlds apart in terms of durability, weight, finish and construction methods. If you are considering metal electric gates It is very important to understand the difference in quality and value is enormous.

Wrought Iron literally means ‘worked iron’, which refers to the method of manufacturing the metal by working (beating) repeatedly under a hammer- it is the same process that steel workers have used for many centuries whether it be making swords or horse shoes. The work of the blacksmith therefore became known as ‘Wrought Ironwork’, a name that has persisted for the art form even though the metal in use may not be wrought iron.

Wrought Iron’s superior weathering properties that are most notable. Wrought iron is known for its durability and will last many hundreds of years, its unique properties allow it to resist corrosion.  Just look at the amount of Wrought iron in heritage sites and buildings that are over 300 years old- Mild steel can last upto 60 years with suitable galvanising.

Wrought Iron is softer to forge, as it is workable at a higher heat than mild steel making it more ‘malleable’ under the hammer. Amazing ornate shapes can be manipulated into the metal to create stunning gate designs with no visible welds.

Today the common material of gate fabrication is mild steel which is a less expensive, readily available and requires a lower skill level to produce gates than wrought iron.  the years we have commissioned many gate designs both in wrought Iron and mild steel- for the vast majority of residential homes mild steel is most suitable product primarily on weight and cost. A substantial pair of wrought iron gates could be as much as 10 times the cost of its mild steel counter parts. It is also important to take into consideration that “wrought iron” gates are many times heavier and very heavy duty gate automation will be required.

How can you tell if your metal gate is wrought iron or mild steel?

If you can see mechanical welds on the outside of a product then it’s very likely to be made of mild steel. If no welds can be seen then further tests would need to be carried out to determine the material used This is not to say mild steel is unsuitable, indeed it is far less expensive to manufacture and weighs far less so the construction process is very different and can be mass produced.

Average cost of a 4000mm opening

Mild steel gates (without galvanising or painting) £2,000

Wrought Iron £12,000 +

In summary, If your gate installer is specifying “wrought iron” I would seek further clarification as in most residential gate installations this would not be the case- it would mean they either do not know what they are selling or are deliberately mis leading you into a sale- avoid these companies at all costs.

Very few electric gate installation companies in the UK have the technology, design flair, skills, finance, customer base or opportunity to create bespoke gates in wrought Iron.

In the words of a blacksmith, “You wouldn’t buy a piece of wooden furniture with the glue on the outside of the joints would you?”.

 

Timber gates comparison – Oak, Iroko, Sapele, Idigbo, Redwood

By Edward Viera- Renzland Powergates Ltd

I served my apprenticeship as a joiner making custom made cabinets, paneling and bespoke timber gates. During my 40 years as a time served craftsman and engineer I have since worked on a varied range of projects including royal properties, historical buildings and overseas projects for private clients.

We are often asked which species of timber is most suitable for gate automation. With increased world demand for hardwoods “growing” (pun unintentional), supplies of quality hardwood has become difficult with prices rising. It can sometimes be difficult when choosing the right timber for your new wooden automatic gate system ensuring value for money.

There are a number of factors that need to be considered by your gate installer before making recommendations- elements such as timber density, drying and kilning process, durability, knots (which can be desirable or undesirable depending on the application), machining, moisture, movement , the acceptability of stain/paint finishes, texture, weight/thickness, manufacturing process and hinge geometry all have an important effect on the overall quality and longevity of the system.

In most cases the final decision by the client is almost always dictated by budget and aesthetic preferences.

Whilst this information is not exhaustive, I have put together a list of the most commonly used timbers for gate automation and my review on each. This review is based on some 40 years experience as a craftsman using all types of soft and hardwood for internal and external purposes and personally over 300 timber gate installations. I was also researched with help from the sites referenced below. It is also important to point out that any automatic timber gate whether is be made from hard or softwood is only as good as the individual components that make up the system (gate automation, ironmongery, supporting posts), design, the installation itself, and of course the ongoing maintenance of the gate system.

Iroko     star iconstar iconstar iconstar iconstar icon 5/5

Iroko is a very durable hardwood. The colour varies from light yellow to golden brown and texture is coarse, often with an interlocked grain. It is indigenous to Africa and is often referred too as “African Oak”   Kiln dried iroko is strongly recommended for external gates.  This is a hard wearing timber which is resistant to decay.  Has many of the desirable features of oak and is commonly used for electric gates, external joinery, boat building and marine work. click here for a case study for iroko automatic gates. or here

Colour                   Poor                          Small                 Medium-High          Very Durable

English Oak  star iconstar iconstar iconstar iconstar icon 5/5

The sapwood is creamy white and is sharply defined from the golden, warm-brown of the heartwood.  If left untreated over time it will weather down to reveal the characteristic silver grain which looks fabulous on older character properties.  The timber is hard, heavy and durable.  Oak is very coarse in texture and straight grained, requiring the correct seasoning, hinging and automation.  It can be worked to a fine finish if necessary. As the name would imply English oak is indigenous to the British Isles, it is probably the best known and one of the most versatile of all timbers, being used more extensively and for a greater number of purposes than any other. However this comes at a cost and using this timber could easily double the cost of the entire gate installation.  For clients looking for top of the range timber electric gates- look no further than Oak. At additional cost we have laser etched crests/emblems into the timber or have it carved for truly personal customisation.

 Sapele   star iconstar iconstar iconstar icon 4/5

Sapele is another hardwood from Africa, the colour dark reddish brown.  Grain is interlocked or wavy with a medium to fine texture.  It stains fairly easily which makes this use of gates easier to maintain in the longer term.  Common uses are usually internal such as furniture, shopfitting, and flooring but is becoming a popular choice to automate timber gates. Sapele can be used as an external wood however it is less durable than Iroko or Oak and has a greater moisture content therefore is can be susceptible to movement which can be offset with the appropriate adjustable hinges. Using sapele for automated gates is a good compromise if a superior hardwood is not attainable due to budget constraints and the option of using softwood is not acceptable.

Idigbo/Emeri star iconstar iconstar iconstar icon 4/5

Colour is yellow to light brown.  The grain is straight to slightly irregular with a medium to fairly coarse texture.  This timber works well by both machine and hand tools and finishes cleanly therefore you can achieve very fine finishes with all the benefits of a hardwood.  Idigbo is an excellent utility timber for many purposes due to its medium weight, ease of working, durability and outstanding stability- in particular for use on timber garage doors and smaller swing gates. Idigbo is not as readily available or mainstream perhaps Iroko therefore the price may be higher. It is perhaps viewed as a more exclusive timber but due to the yellowish colour it is an acquired taste.

 Redwood star iconstar icon 2/5

Redwood is a popular softwood used for gate automation, typically 5 bar farm gates- Usually sourced from Scandinavia, Russia and the UK is is also known as pine and Scot’s Pine, its colour is pale yellowish-brown to red-brown heartwood with lighter-coloured sapwood. Gates made from Redwood should be treated every 1 to 2 with water-repellent preservative stain , depending on the environment. We would strongly recommend pressure treated softwood gates to ensure the longevity of your gate investment.

Legend-

Paint-Stain This refers to the ease of accepting a stain or paint finish. Oils are recommended for hardwood gates due to ease of application and finish.

Moisture          Moisture movement- the dimensional changes that occur when dried timber is subjected to changes in atmospheric conditions. For situations where varying humidities are likely to be encountered and stability of a component is important, a small movement species should be specified for electric gates.  The most recent standard for moisture content in general is BSEN 942 1996 Timber & Joinery.
