Stair Strip Steel

After some successful experiments, Cobra, together with its customers, has developed a hardened strip steel line with alternating thicknesses.

Despite extremely high requirements concerning the minimal cross curve of the highly carbonic strip steel (0.02% max. of the material’s width), the firmness acquired is more than 60 HRC. Due to the cascaded profile of the material, this strip steel material was lovingly nick-named “Stair Strip Steel”.
