Aluminium door colour range
Choose the colour that suits you, over 200 RAL colours. We offer smooth matt and metallic paints that have a texture or have the so-called special effects (mainly wood-like).

Door structures
Modern architecture often requires from us to design door structures with different dimensions, shapes, specifications, etc. They determine not only the look of the door but also its functional properties, stability, and durability. The spacers used in Drutex doors help significantly increase door rigidity and at the same time ensure a unique, custom design.
Glass types
We provide a diverse selection of glass for windows and doors that meet high standards for energy efficiency, sound insulation, and security. Our range includes laminated, sun-protected, sound-insulated, tempered, ornamental, and sandblasted glass.




















Door handles and pulls
Our handles for windows, doors and terrace systems made of PVC, aluminium and wood are distinguished by their high aesthetics, functionality and durability. Thanks to various colour options, they can be perfectly matched colour of the windows, doors, or the colour scheme of the building.
