Multileafed doors with bottom guide rail Moreschi FOLDING doors can be installed indoors or outdoors, to make the most of the versatility of folding packing and leave ample room for manoeuvre. The Folding door consists of 52 mm thick leaves; the internal perimeter frames in 20/10 thick galvanised steel profile are fully foamed and insulated. The doors are covered with smooth or peeled sheets 8/10 thick, obtained through a continuous rolling process in SENDZIMIR galvanised steel; this is followed by phosphating and the application of 5 Micron thick primer on both sides. On the external side is applied the finishing varnish with a thickness of 20 Micron. The surface thus obtained is completely smooth. The 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 an average density of 43/45 Kg/m³, obtained through an under-press expansion process that ensures a high degree of thermal insulation. The black upper rail has a double modular rail and is equipped with: trolleys with bearings; lateral flag for the collection of the doors and other accessories, so that it is already prepared for any motorization. For the solution on a single pack, the side stop post is made of galvanised steel with 120x40mm section and fixed with special galvanised steel fixing brackets.
