Double hinged leaf

Hinged metal door with the frame made of bended electro-zinc coated steel profiles (1.5 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 and acoustic materials according to the TRIA constructive system.
The high level sound attenuation is ensured by acoustic joints and can be increased adding a threshold. The leaf’s bottom contains an automatic seal.
The pivoting fuction of the door is ensured by three exclusive hinges of this series. If desired, the hinges can be hidden by extending the panel of the leaf, on all three sides in order to maintain the symmetry of the door.
