Then there is this extraordinary technical development. The B-Fix Bi-metal screw. A self drilling screw for metallic structures. Thanks to the Bi-metal, the B-Fix One can finally be used straight on galvanized steel, stainless steel or aluminum girders with a thickness of maximum 6 mm. So it's not necessary any more to put a wooden joist between the decking and the steel structure. This technical development has also been imagined in both colors: silver and black.
