Sectional garage door PROFI

steelgalvanised steelpolyurethane foam

The sectional steel garage door has been designed for everyday use. The 40 mm thick panels, filled with polyurethane foam, provide good thermal insulation (U = 1.3 W/m²K) and high panel rigidity. The joints between the segments are equipped with seals that help prevent wind and moisture from entering, which improves the tightness of the entire structure. The guide rails and hinges are made of galvanised steel, resistant to corrosion. The bearing rollers support smooth door operation without jamming or noise. The whole structure is solid, well-fitted and suitable for intensive use. The garage door features a torsion spring system mounted at the front of the lintel. This solution evenly distributes the weight of the door, resulting in smooth movement and easy operation. The springs are made of galvanised steel and are tested for 20,000 operating cycles, ensuring many years of trouble-free operation. If one of the springs breaks, a safety mechanism stops the door, preventing it from falling. The entire guide system is designed to maintain the stability and balance of the structure at every stage of movement.
