The special design of the windows (dimensions 600*300 mm) provides communication between the interior and the exterior, thereby increasing the interior lighting. The household is made of high-strength acrylic board.
The torsion spring can be equipped with Dacromet coating process. A layer of anti-corrosion film is formed on the surface, which is isolated from the air to protect the torsion spring.
It is recommended that the door be equipped with a baking varnish material (standard configuration is galvanized material) when operating in high humidity conditions to ensure reliable anti-corrosion protection and stable operation of the door.
The door-in-door is equipped with an interlocking device between the small door and the large door. When the small door is not completely closed, the large door cannot be opened to ensure safe use.
