Nooyen aims for a long, durable life of its Tri-Bar slatted floor by using high resistant steel instead of standard reinforcing steel (FeB 500). High resistant steel is a high quality alloy with a high nickel, chromium and copper content and a highly specific amount of silicon. Compared with standard reinforcing steel, high resistant steel has a highly accurately determined and therefore consistent composition.
The steel is cold formed and thermally galvanized. The zinc coating has an average thickness of 100 to 130 micron. As high resistant steel can be coated with more zinc than standard reinforcing steel, it has a longer life. Thanks to the use of high resistant steel, the quality of the slatted floors marketed by Nooyen far exceeds NEN-EN-ISO 1461 standards.
