BRIGHT STEEL

If you need everything to go smoothly.

Bright steel is characterized by a smooth, bright and scale-free surface as well as high dimensional accuracy. Good testing possibilities for imperfections as well as the suitability for surface refinement enable lower processing costs, higher work productivity and lower material losses compared to hot-formed steel. Bright steel is therefore used not only because of its defined material properties, dimensions and tolerances, but above all for reasons of economy.

The main areas of application for bright steel are in the automotive industry, mechanical engineering, the electrical and hydraulic industries or in the manufacture of connecting elements.

As a focal point of our product range, we stock a standard bright steel range with a large number of steel qualities in a wide variety of shapes and configurations using cutting-edge storage technology. A distinction is made between the types of drawn, peeled and ground bright steel.

Drawn bright steels are steel products of various cross-sectional shapes manufactured from hot-rolled bar steel or wire rod after descaling by drawing on a drawing machine (non-cutting cold forming). The resulting work-hardened material gets, among other things, greater yield strength and tensile strength and is always straightened regardless of the dimension. Peeled bright steel is round steel produced by peeling and then straightened and/or pressure-polished. The cutting process offers the advantage that the surface is almost free of preliminary material defects and edge decarburization. Ground bright steel is drawn or peeled round steel, which is given an even better surface finish and even higher dimensional accuracy by grinding and polishing if necessary.
