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.
Lateral and superior fixed panels can be attached if its composition is similar to the leaf. 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. Door models with
CE marking according to EN 14351-2 (possible after the its publication).
