This type of door is characterized by various notching and shaping processes on the sheet metal, creating an attractive visual effect. The glass panel defining the opening can be supplied in different colors and can be replaced without needing to change the door leaf.

Its basic construction features a door leaf made of 1 mm thick sheet metal with internal reinforcements, box-shaped, hollow-core, and press-bent edges forming the sealing flange against the frame. The frame is made of 1.5 mm thick sheet metal with pre-drilled holes for cable passage, slots for fixing anchor brackets, and stamped anchors for masonry installation. The door has a total thickness of 52 mm and is equipped with two stamped three-wing sheet metal hinges rotating on stamped ball bearings. An adjustable mechanical device and damper ensure smooth closing, keeping the door leaf securely shut.

The door leaf includes a door stop strip and sealing rubber gaskets.
