aluminumsteelgalvanized steel

The glazed sectional door is made of natural anodised aluminium elements 42mm thick with variable height. Thanks to the special design of the door elements, there is no risk of crushing fingers on the outside or inside. Internally, the panel is reinforced with sturdy steel plates that guarantee secure fastening of the hinges and all other accessories. Filling with transparent and extremely scratch-resistant synthetic material. The lateral and upper sliding guides are made of steel with a galvanised finish, suitably shaped so as to obtain maximum rigidity and minimum overall dimensions for assembly. The suspension of the sliding guides on the ceiling is carried out by means of galvanised steel brackets with slots to be adapted to each installation situation. The trolleys that slide in the guides have nylon wheels with steel supports. The hinges connecting the panels and the supports for the trolleys are made of steel with a galvanised finish. To cushion the door when opening, galvanised steel shock absorbers are installed in the final part of the guides. The movement and counter-balancing of the door is guaranteed by a special shaft with appropriately sized painted torsion springs. In the event of a spring breaking, the door leaf is prevented from falling down thanks to the parachute system; this device is integrated in the suspension system and depends on the load and is equipped with a stopping tooth and active against the breakage of the rope or spring (European Patent)
