  • Metallic coated - High-strength steel (US Standard units)

    Our range of metallic coated high-strength steels includes micro-alloyed, phosphorus-alloyed and bake-hardening grades. Available with various corrosion-resistant coatings, they are ideal for applications requiring strength without a weight penalty. MagiZinc® coatings optimize weight savings.

    • Metallic coated steel - Magizinc®

      MagiZinc® improves corrosion resistance with half the thickness of conventional zinc coatings, increasing yield, reducing cost and facilitating stronger, lighter products.

      It offers improved automotive corrosion protection and higher process efficiency.

    • Metallic coated - advanced high-strength steel

      Our ultra-high strength steel grades for automotive applications, such as HyperForm®, are lightweight and offer design freedom for complex parts. Their high yield and ductility ensure shape accuracy and tolerancing, which enable maintained in-service performance for difficult-to-form parts.
