Surface finishing for corrosion protection

Coated sheet steel from thyssenkrupp Steel

Cold-rolled flat products that are prepared for a wide range of demanding applications by hot-dip coating and electrolytic finishing.

More than 80% of our cold-rolled steels are finished with various high-quality surfaces. This results in products with very good flatness, low coating thicknesses, high corrosion protection and good formability combined with maximum strength, for example with metallic coatings of pure zinc, zinc-iron or zinc-magnesium.

The combination of a zinc-aluminum alloy to achieve particularly high corrosion resistance is also possible, as with the galfan® coating variant. We also offer electrolytically galvanized sheet as well as special products made of hot-dip aluminized (AS-coated) manganese-boron steel and special textures such as primetex®, which is the basis for an outstanding paint appearance.

Spectrum of surface finishing

Thanks to our more than ten finishing facilities, we are in an excellent position to cover the entire spectrum of metallic and organic coatings.
