The series of the aluminium doors “DK” and “D1M” worked out by our represented plant are the compatible systems of technical decisions which allow to make different types of doors: single or two-leaved doors, with partial covering or fully glazed, with the intensifying steel framework or without it and also double swinging doors.

The three-chambered “warm” extrusion, consisting of two outward extrusions, connected by a bridge of polyamide reinforced by the fiberglass of the “Technoform” company (Germany), is used in the “DK” series. It is fitted to be glazed by glass pack with thickness 23 mm and 28 mm.

In the series “D1M” – our represented plant uses one-chambered “cold extrusions”, which are appropriate for the single glazing with glass packs of  23 mm thickness. Building thickness of extrusion is 44 mm.

Door constructions provide durability, reliability, economy of exploitation and also minimum labour-intensity at making and editing.

Aluminium profiles' surfaces are coated (for colouring and surface protection) using two different technologies:

• Anodize. Possible colours: natural aluminium, gold, aged-bronze, black;
• Coating with polymer paints. Possible colours: all RAL colours.
