Panels (MDF) coated with PVC film of various colours are used for the finishing/decoration of the door. The elements of the panel are first of all cut out during the manufacturing process, then each element is laminated separately, and only after that the panel is assembled into an integral pattern. Patterns of exclusive design and forms are created in this manner.
The hinges are with supporting bearings. Stationary tempered pins protect the door from being taken out after cutting the hinges thus ensuring greater security.
The jamb (door frame) is made from folded steel profiles. The metal construction of the sash and the jamb (door frame) are painted with powder paint.
