SM490 Structural H Shape Iron Beams

Product Description

SM490 Carbon Steel H-Beam

Our SM490 Carbon Steel H-Beams are engineered for critical structural applications that demand higher strength and superior welding performance. The “SM” designation stands for “Steel for Welded Structure,” indicating its optimized chemical composition and controlled carbon equivalent to ensure excellent weldability without preheating in most applications. With a minimum yield strength of 325–365 N/mm² (depending on thickness) and tensile strength of 490–610 N/mm², SM490 delivers the performance required for challenging structural environments.

Material Grade: SM490 (JIS G3106) | Equivalent to S355JR, ASTM A572 Gr.50, Q355B

Type: Hot-rolled H-Beam / Wide Flange Beam

Welding Performance: Optimized carbon equivalent (Ceq) for excellent weldability; suitable for arc welding, gas welding, and spot welding

Processing: Cutting, drilling, welding, and bending available upon request

Surface Treatment: Bare, oiled, anti-rust primed, or hot-dip galvanized

Quality Assurance: Mill test certificates (MTC) provided; third-party inspections (SGS, BV) accepted
