Fixed Steel Frames

Steel frames are made of 1.5 mm thick low-carbon steel sheet, protected with a varnish, organic protective coating. The casing consists of two stands: hook and hinge (in the frame for double-leaf doors, both hinge stands) and lintels, permanently connected with each other by welding. Hinge stands are equipped with hinge sockets, while the hook stands have cutouts for the tongue and lock bolts of the dedicated door leaf (the set includes a cover gasket). The frame profile, its dimensions, equipment and colors depend on the selected variant – the type of door to which the frame is to be used.

The door frames are powder coated in two gloss levels: matt / fine structure or semi-gloss / smooth.
