Weldox has been upgraded to Strenx® performance steel
In 2015, SSAB’s high-strength structural steel brands Weldox and Optim, together with the best products from the Domex® and Docol® brands were combined into one. Their legacy lives on in Strenx® performance steel.
The power of Weldox, Optim, Domex and Docol. In one brand.
Strenx® offers the world’s largest selection of high-strength structural steels, in terms of both strength and dimensions. Yield strengths range from 600 MPa to 1,300 MPa – the strongest steel available on the market. Strenx® is available as sheet, strip and tubular products in thicknesses from 0.7 mm to 160 mm.
