Sectional Overhead Doors

Each sectional door can be customised with a range of control, glazing and colour options to meet your business’ individual requirements.

Sectional doors are specified in industrial applications where large openings require coverage. The doors comprise panels manufactured from composite materials and steel bands, providing strength, insulation and security. Heavy duty electric motors are combined with the highest quality access control systems for high frequency entranceways, with manual spring loaded operation available for smaller openings. Overhead and vertical lift options are available, including solutions for pitched roofs and spaces with low headroom.

FlexibleOur 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.
ReliableOur 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.
DurableYou 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 LifeThanks 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.
CertifiedTo 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 ValueOur 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 measureOur 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).
TracksA 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 & HardwareSteel 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 EquipmentThe 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.
