Specifications

The model of fire resistant door with guillotine opening is manufactured with different degrees of fire resistance. It is done with a single sheet made of joined panels, assembled with gaskets that are resistant not only mechanically but also to fire. Each panel , of an approximate width of 1 200 mm, consists of two sheets of galvanized steel and a set of thermal materials that prevent that gases or flames getting through. This sheet is topped with a closing profile around the whole perimeter and, in case of lack of space, the door is manufactured with two telescopic sheets.  Thanks to its complex design and if necessary, in this kind of door it is possible to add a spyhole in the sheet.

The fire resistant guillotine door remains usually open and, when it receives a signal from the fire detection system, descends by gravity to a rate controlled by respective radial absorbers. It closes then to the ground without hitting against it, thanks to shock absorbers. They also have appropriate safety equipment to prevent falls in case that an element of the suspension breaks.

The guides of the door can be installed on the ceiling or be welded to resistant metallic structures. The support elements should have, at least, twice the fire resistance than the door, and they should be robust enough to withstand the weight of the door and its expansions.
