  • Metallic coated - Structural steel

    Tata Steel’s metallic coated structural steel behaves reliably in roll-forming and bending processes and is suitable for welding.

    For exceptionally demanding applications, we have grades that exceed the minimum strength levels specified in EN 10346:2015.

    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.

    1. If the yield point is pronounced, the values apply to the upper yield point (ReH).
    2. For all grades except S550GD+Z a range of 140 N/mm² can be expected for tensile strength.
    3. For a thickness t ≤ 0.7mm the minimum elongation after fracture is decreased by 2% and for a
       thickness t ≤ 0.5mm the minimum elongation after fracture is decreased by 4%.

    1. If the yield point is pronounced, the values apply to the upper yield point (ReH).
    2. For all grades except S550GD+Z a range of 140 N/mm² can be expected for tensile strength.
    3. For a thickness t ≤ 0.7mm the minimum elongation after fracture is decreased by 2% and for a
       thickness t ≤ 0.5mm the minimum elongation after fracture is decreased by 4%.
