Product Overview

S235JR hot rolled I-Beam is the widely adopted European standard carbon structural I-beam, equivalent grades Q235B(GB), A36(ASTM) and SS400(JIS). It is manufactured according to EN10025, GB/T706, ASTM A6 and JIS G3192 specifications.

The I-shaped cross-section provides strong bending resistance for structural load-bearing. S235JR I-beam features good plasticity, great weldability and simple processing performance. It can be cut, drilled and welded without complicated heat treatment.

This grade I beam is the preferred option for European standard civil construction, general building frames, support brackets and light-medium load structures. We supply full size range hot rolled S235JR I-Beam, surface options include black, shot blasted or pickled. Custom cut length service is available.
