Sectional Overhead Doors

Product details

Flexible Our sectional overhead doors are constructed from Kingspan composite steel, allowing you to specify the format, functionality and appearance you desire. Indupart’s sectional overhead doors can be supplied in any RAL colour.
Reliable Our sectional overhead doors are produced at our Stockport production warehouse. We have been delivering, in accordance with the agreed specifications and delivery times, quality doors from our own factories for over 30 years. We keep our quality standards high with product innovation and extensive internal quality control. Our products make us the market leader in the UK.
Durable You want a sectional overhead door that completely meets your needs and will operate problem free for many years. The panels in our doors are perfectly protected against corrosion, thanks to the use of highquality materials, which are galvanised and coated. This guarantees a long life, even when exposed to extreme weather conditions.
Long Life Thanks to the extra thick steel skin, that is galvanised and coated, the doors are optimally protected against deformation and corrosion. You are ensured that your door will have a long life.
Certified To guarantee the quality and safety of industrial doors, the European Commission has established (European) guidelines in the EN 13 241 1:2003 standard. All of our sectional overhead doors meet the requirements specified in this CE NEN standard. This has been determined by the accredited Swedish research centre SP Technical Research Institute of Sweden.
High Insulation Value Our sectional overhead doors are made of 40-millimetre thick steel sandwich panels/sections (80mm are available). The male-female construction ensures that they fit together almost seamlessly. The front and back skins of the panels are made of extra thick steel. These skins are separated by Kingspan’s unique firesafe foam.
Made to measure Our sectional overhead doors are manufactured to the exact specified size and assembled and installed on site. If required, our doors can be fitted with a wicket door and/or windows. The sectional overhead door can be operated manually, semi-automatically (with a chain hoist) or fully automatically (with a GfA operator).
Tracks A track system is used when opening and closing a sectional overhead door. This system consists of a set of rails, the springs and the operating equipment. The track system forms the silent strength of every sectional overhead door. Our tracks are always custom made and all made from high-quality galvanised steel. A track is designed and made to measure in our factory for every sectional overhead door. The quality of the track determines to a large degree the life of your sectional overhead door. The roller carriers are adjustable and along with the intermediate panel hinges, are hot dipped galvanised steel. The rollers that run in the side track are sealed for life, self-lubricating bearings with a nylon tyre to give a smooth and quiet operation.
Springs, Hoisting Cables & Hardware Steel lifting springs and cables are used to open the sectional overhead door and keep it open. The springs are high quality and have a long life. They are shot blasted, powder coated and oiled when delivered. Special springs are available for overhead doors that are used frequently. The hoisting cables are six times over-dimensioned for additional safety.
Operating Equipment The sectional overhead door can be operated manually, with a chain hoist or by an electric motor. We can advise you of the possibilities and advantages of each mode of operation.
Spring Brake Device If a spring of the track system breaks (for instance at the end of its life), it is possible for the overhead door to suddenly shut at great speed. For manually operated doors especially, this can result in dangerous situations. Therefore, these overhead doors are fitted as standard with an obligatory spring brake device. If another mode of operation is used, the spring brake device can be fitted as an extra option.
Safety Edge & Light Curtain A safety edge or a light curtain be fitted to electrically operated overhead doors for additional safety. With the safety edge installed, when the door is closing it will stop and automatically reopen if the safety edge is touched. The light curtain secures the entire door opening. As soon as someone or something is detected in the door opening when the door is closing, the door will automatically reopen.
Cable Break Safety Device (Recommended) In the unlikely event that one of the cables of the guide rail system breaks, an unsafe situation can develop when opening or closing the door. To reduce the risk of a cable break, we over-dimension the cables six times. This reduces the probability of both cables breaking at the same time to almost zero. Although when using our cables it is not obligatory to fit a cable break safety device, Indupart fit them as standard.
Finger Protection Finger protection is obligatory (CE standard) for overhead doors up to a height of 2.5 metres (the height of the pivot point of the top section). Finger protection is not obligatory for higher sectional overhead doors, but offers extra protection.
Door Panels Kingspan 610mm x 40mm thick composite panels manufactured using 0.45mm outer and 0.4mm liner, continuously hot dip, zinc coated structural steel with internally mounted steel bands to accept self tapping fixings. Insulated with Kingspan’s unique Isophenic (IPN) Core (providing optimum fire performance as standard) giving an optimum panel ‘U’ value of 0.51 W/m2 K. This means a typical door of 4000 x 5000 ‘U’ value of 0.9 W/m2 K. Better ‘U’ values are achievable using 80mm Kingspan composite panels on request.
Safety Edge You can also select a safety edge to be fitted on electrically operated overhead doors for additional safety. If the door closes while someone or something is under it, the safety edge stops the door automatically.

    Frequently Asked Questions

    Investing in any form of secure door system requires a relative outlay and prior to purchase it’s important to feel fully confident in the company you choose.

    We have compiled a list of some questions that are worthwhile asking when researching and requesting quotes.


    Do your secure doors meet the relevant UK health and safety standards?

    Whether buying power-assisted gates or doors, these MUST be fully compliant with UK law. It’s important to understand and even request evidence to prove that everything is above board. Once purchased, companies then become responsible for maintenance whilst ensuring the safety of use based on specific circumstances.


    Does your company have public liability insurance in place?

    This may seem like a question you’d never ask but it’s certainly an important one. Without insurance, should something go wrong during installation, the customer could be landed with a costly and unexpected bill. This seemingly bold question should never be a problem, especially to a business who’s covered.


    Do secure doors come with a warranty?

    Again, we’ll highlight the fact that secure doors are an investment. It’s important to know they are going to be under warranty, even if it’s only for a short time. When using a reputable company the topic of warranties will be discussed in the first instance. If not, don’t be afraid to ask or request paperwork.


    Do you provide support after purchase?

    The worst thing any company can do is vanish once the deal is done. Having mentioned health and safety above, it’s intrinsic to to understand that high levels of safety must continue. Again, a company with a decent reputation will discuss this initially whilst recommending maintenance services. Make sure you’re fully aware of your responsibilities as a company owner with regards to secure door systems.


    What times of the day can we get in touch?

    As not every company works the traditional 9am – 5pm shift pattern, you’ll need to be fully versed with applicable times to call, especially in the case of an emergency. Ideally, a secure door provider will be available 24 hours a day, 7 days a week. When this is the case, should you experience a breakdown, help will be on its way sooner resulting in less downtime and revenue loss.

    Aftercare & ongoing support
