Applications & Selection Guide

Hot-rolled from continuously cast billet on a fully continuous mill, in structural grades S235JR, S275JR, S355JR and S355J2, ASTM A36, A572 and A615, carbon grades SAE 1010 to 1060, and the older ST 37-2 to ST 60 designations.

Widths from 10 mm to 160 mm and thicknesses from 3 mm to 60 mm; each size page gives the weight per metre. Used for base plates, brackets, fishplates, stiffeners, gates and general fabrication.

Standard length is 6 m; other lengths on request. The minimum order is 5 t per size. Grade, tolerances and lead time are confirmed in our quotation. The mill works to ISO 9001, its products carry CE conformity, and each delivery comes with a mill test certificate.
