Single or double hinged leaf

Hinged metal door with the frame made of bended electro-zinc coated steel profiles (2 mm thickness) welded to each other. On the hinges side are welded steel spikes which engage the leaf’s top when the door is closed.
The leaf is made of two electro-zinc coated steel panels (0.8 mm thickness) and contains thermal insulating materials according to the TRIA constructive system.
The use of intumescent joints ensures the necessary tightness against flames and hot gases.
The pivoting behavior is ensured by two hinges in symmetrical positions with axial bearings. If necessary, it is possible to incorporate an intumescent grid in the leaf.
