Hermetic and protective metal doors for shelters

A new development from Paritet-K is a hermetically protective metal door for shelters. The doors are intended for use in shelters, bunkers, storages and as an emergency exit for technical rooms to protect against blast waves and fire. The door withstands the load from an explosive wave of 0.2 kgf/cm.sq. The total thickness of the door is 71 mm, the protective layer is filled with fire-resistant filler. Tight closing occurs by means of four mechanical levers that press the door to the box and expand the rubber seal. In addition, thermal tape is pasted around the perimeter of the door, which seals the door in the event of a fire. The doors are reversible, that is, they can be installed both on the left and on the right. The size of the door passage in the light is 900 mm by 2000 mm.
