The products are normalised after cutting. This prevents tempered zones in the cut surface, and results in a highly malleable material. Our TTSTE 355 Z3 steel is the product of a long-standing and successful partnership with the largest suppliers to the Norwegian offshore industry.

We constantly maintain an inventory of steel plates of 1,000 to 1,500 tonnes, with thicknesses of 80 to 720 mm. We also have or can procure forged shafts up to 1,200 mm in diameter.
