JIS standard H-beam SS400 steel
JIS SS400 steel h beam is a structural steel grade specified by the Japanese Industrial Standard (JIS G 3101). "SS" stands for "Steel Structure" and "400" indicates a minimum tensile strength of 400 MPa. H beams (or I-beams) made from SS400 have excellent strength-to-weight ratio and weldability and are widely used in construction and engineering.
Manufacturing Standards
JIS G 3101: Specifies requirements for hot-rolled carbon steel used in structural applications.
H beam dimensions: Follow JIS G 3192 (Hot-rolled H beam dimensions, weights and tolerances).
Applications of SS400 h beam structure
Building Frames: Columns, beams and braces in commercial/residential structures.
Bridges: Secondary load-bearing members.
Machinery: Base frames, cranes and heavy equipment.
Industrial Equipment: Platforms, racks and storage systems.
Processing and Fabrication of SS400 h section beam
Welding: Good weldability, preheat (100-150°C) for thick sections to avoid cracking. Common methods include SMAW, GMAW and FCAW.
Processing: Easily processed with standard tools.
Surface Treatment: Typically galvanized, painted or primed for improved corrosion resistance.
Comparison with Similar Grades
JIS SS400 vs. ASTM A36: SS400 has a slightly higher carbon content than A36, but comparable mechanical properties.
JIS SS400 vs. EN S235JR: SS400 has similar yield strength but different chemical composition
Advantages of SS400 structural steel h beam: Cost-effective for general structural use; good balance of strength and ductility; widely used in standard H-beam sizes.
