Hot Rolled Steel Profile H Beam SS490
What is SS490 H-beam?
SS490 is a Japanese Industrial Standard (JIS G3106) carbon steel grade designed for structural applications that require higher strength than SS400. The H-shaped cross section optimizes load distribution and is suitable for large frames, bridges and industrial projects under dynamic or heavy loads.
Key Benefits of SS490 Hot Rolled H-beam
Superior Strength: Higher yield strength and tensile strength compared to SS400 h beam profile.
Enhanced Durability: Resists deformation under extreme stress.
Weldability and Machinability: Compatible with standard fabrication techniques.
Mechanical properties of SS490 h profile steel
Yield strength≥325 MPa
Tensile strength490-610 MPa
Elongation≥17% (minimum)
Carbon content≤0.30% (to ensure weldability)
H-profile steel design minimizes weight while maximizing bending and shear resistance.
SS490 steel h profile is widely used in
High-rise buildings: core columns and floor beams to support vertical and lateral loads.
Heavy machinery foundations: foundations for cranes, presses and industrial equipment.
Bridge construction: girders and trusses requiring fatigue resistance.
Warehouses and factories: long-span roof structures and load-bearing frames.
Seismic zones: earthquake-resistant design due to its ductility.
Main differences between SS490 h beam section and ASTM A572 h steel profile
While ASTM A572 (US standard) offers similar strength grades (e.g. Gr 50), SS490 has stricter elongation requirements and better ductility under dynamic loads.
