Single or double hinged leaf.

Hinged metal door with electro-zinc coated steel frame (1,5 mm thickness), cold-formed and construction by welding. A rubber peripheral sealing gasket is embedded in the frame.
The leaf, with a door stop edge in all three sides of the frame, is made of two electro-zinc coated steel panels, ranging from 1 to 1,5 mm thick, and contains thermal insulating and acoustic materials according to Schröders constructive system.
The pivoting behavior of the door is ensured by two welded hinges of the system (per leaf), with a 16 mm diameter solid steel pin and movement on thrust ball bearings, allowing an opening up to 180º.
