Sliding door

galvanized steelinsulatedlarge

For large openings: excellent robustness and maximum functionality, this is synonymous with a guarantee. Large openings, minimum space requirements: the insulated door solves the problem of leaf collection. When installed inside the building, it can slide between the wall and the shelving or machinery, making it almost "invisible". Our doors are made of materials that, even when installed outdoors, do not create complications. The floor sliding door consists of 52 mm thick leaves with respective internal perimeter frames in 20/10 thick galvanised steel profile. The doors are entirely covered with smooth or peeled sheets obtained through a continuous rolling process, in galvanized steel SENDZIMIR system, followed by phosphating and the application of 20 Micron thick primer. This pre-painting offers, without any alteration, the resistance of 400 hours in a salt spray chamber. Finally, we prevent scratches by applying adhesive film to be removed after installation. The insulation is guaranteed by the injection of self-extinguishing polyurethane foam according to DIN 4102 class B2, with a density of not less than 43/45 Kg/m³, obtained through an under-press expansion process that ensures a high degree of thermal insulation. The upper rail is fixed in veletta or to the ceiling by special brackets designed and manufactured by us, all in galvanized steel. The upper sliding is guaranteed by nylon olives which guarantee silence and great manoeuvrability. The whole is covered with pre-painted and silicone-Curtained sheet metal casing in the upper part.
