Sectional doors are robust yet stylish doors constructed of several panels. They offer excellent insulation and can be constructed to open directly up, or where space is an issue they can be fitted in an “up and over” manner whereby the door curves to lie horizontally when open.
For processing or cold store applications it is common to use sectional doors due to their security and insulation values. We also frequently install sectional doors paired with a rapid roll for external applications; this provides fast access during the day and allows the sectional door to be closed at night. This is often a more efficient and cost-effective solution than using insulated roller shutters.
The sectional doors we supply are suitable for every type of building. The doors have been designed for durability and efficiency. The springs are engineered to withstand 20000 cycles and the bearing rollers compromise dustproof, self-lubricating bearings and a wear resistant nylon surface. The panels are thermally insulated consisting of double walled galvanised steel plates with a CFC-free polyurethane foam filling. The panels are also finger safe.
All the individual components of the overhead doors are first produced and subsequently galvanized. This provides perfect protection against corrosion.
Each track system is tailor-made, taking into account the conditions on site.
There are three basic systems for operating the overhead doors:
There are various options in the area of safety and security including protection against spring and cable break and slack cables, the doors can also be fitted with a safety edge and a pass door switch.
The great versatility of the sectional door comes from the fact that there are so many configurations possible. This means that whatever the location, there will be a suitable configuration.
The door can be supplied in a range of colours. The inside of the panel is RAL 9010 (White), while the exterior has a polyester coating which can be finished in any of the range of RAL colours.
The standard choice of RAL colours are shown below:
All our industrial type panels with traditional tongue and groove joints have the following features:
Vision windows can be built in to the design of the door, in fact it is even possible to have the whole door constructed to be see through!
All our doors can be fitted with an electric motor so the door can be automatically opened and closed. The alternative is to fit the door with a chain for manually hoisting and lowering the door, which is great for saving on electricity but can get to be hard work if you need to use the door often!
The control panel can be supplied with a range of accessories including remote controls, photocells and safety edges.
A built-in pass door can be fitted in any overhead door with a width of up to 5000mm. The pass door profiles are fabricated from anodised aluminium. Dependent on the type of overhead door, the pass door can be fitted with an electric security switch so that the door cannot be operated whilst the pass door is open; this is mounted invisibly.
The STA and TVR ranges of operators mount directly to the spring shaft of the door.
All operators have a manual override facility to open and close the door in the event of a mains power failure, this can be achieved by a disengage clutch, floor level or high level hand chain systems. For Fire stations and Ambulance stations where speed of opening is critical under all circumstances the VRFCU operators can provide rapid emergency manual hand chain.
Our standard operators power ranges from 0.37Kw to 0.75kw, though we can provide larger powers when needed for larger applications.
All operators have are provided with the following standard features:
All the doors are designed, tested and certified with the latest use and safety regulations as determined by the European Standardization Committee, CEN. According to CEN, maintenance of sectional doors is required at least once a year. We can arrange for the maintenance of your doors with you.
