SM490A Steel Hot Rolled CS I-Beam Universal Construction Iron

Product Description

SM490A Steel Hot Rolled CS  I-Beam

Our SM490 I-Beams are hot-rolled from high-quality low-alloy steel, featuring a well-proportioned “I” cross-section that provides outstanding resistance to bending, shear, and torsion. The controlled chemical composition and rolling process ensure fine grain structure, enhancing both strength and toughness. Each beam undergoes strict quality control, including precise dimensional inspection, straightness verification, and surface finish assessment. With excellent weldability (suitable for heavy welding applications) and good formability, SM490 beams are ideal for complex fabricated structures. Mill test certificates (EN 10204 3.1 or JIS-compliant) accompany every shipment for full traceability.

Minimum yield strength: 325 MPa (for thickness ≤ 40 mm, depending on grade variant)

Excellent weldability – designed specifically for welded structures

High toughness and impact resistance (27 J at 0°C for SM490A; lower temperature grades available)

Fully compliant with JIS G3106 (SM490A / SM490B / SM490C variants)

Superior strength-to-weight ratio compared to SS400
