Industrial sectional doors are the most durable and longest lasting doors to ensure circulation at the areas of the factory entrance and exit of goods, loading and unloading areas.
The body of sectional door is forming by 40 mm sandwich panels. These panels provides sound and heat insulation due to the intense doped polyurethane insulation was injected between galvanized steel sheet. (50 kg/m3).
Industrial sectional door systems provide space-saving with opening parallel to the ceiling.Any opening can be used clearly . and produces in accordance with the transition range and the height in the factory buildings or warehouses.
Doors is working sliding by be the most appropriate the gap between the top level of the gate with a ceiling height within the side rasils. The door can be mounted in different ways according to the gap distance (standard, low, highlift and vertical track systems).
Industrial sectional doors can easily be opened automaticly by 230-380 V-AC/50 Hz electric motor or manualy thanks to torsion spring system that balances the weight of the door.The galvanized springs are made to be durable of 25.000 door cycles.Motor with emergency chain All the drive systems have a mechanical back-up system fitted to the reduction gearbox of the electric motor, so that the sectional door can be opened if the power fails. The reduction gearbox can then be powered using the chain.
