The production of bullet resistance steel door is based on unique technology, which involves procedure of joining steel sheets in door leaves by bending and mechanical joints. This solution guarantees high resistance to corrosion and perfectly smooth surface of the door leaf.


The doors are made of steel sheets. Door leaves are filled with ballistic fiber glass armour panels with vertical stiffener of high density depending on the type of the door.
