1. High strength and structural stability
SS400: Basic carbon structural steel, tensile strength ≥400MPa, suitable for general building frames and mechanical parts, cost-effective.
SS490: Medium-strength steel (tensile strength ≥490MPa), balancing strength and cost in bridges and plant structures.
SS540: High-strength steel (tensile strength ≥540MPa), suitable for heavy-duty structures (such as high-rise buildings, port machinery), reducing weight while improving safety.
H-section design: large section inertia, excellent bending and compression resistance, more material saving than I-beams.
2. Excellent welding and processing performance
Low carbon equivalent: All three grades are easy to weld, reducing the need for preheating and post-weld treatment, and reducing construction complexity.
Cold bending formability: SS400/SS490 is suitable for secondary processing such as cutting and drilling, and SS540 maintains high strength and toughness through component optimization.
3. Wide range of application scenarios
Construction: high-rise steel structures, industrial plants (mainly SS490), temporary support structures (SS400).
Infrastructure: bridge trusses, transmission towers (SS540 has outstanding fatigue resistance).
Machinery manufacturing: crane arms, transport equipment frames (SS540 has obvious high strength advantages).
4. Economic and environmental protection
Material efficiency: H-shaped steel has a reasonable cross-sectional distribution, uses less steel, and reduces the total cost of the project.
Recyclability: The entire series of steel can be 100% recycled, meeting green building standards.
5. Standardization and supply guarantee
Comply with JIS G3101 standard: stable quality and high international recognition.
Complete specifications: Covering a variety of sizes such as 100mm×100mm~900mm×300mm to meet diverse needs.
Summary: SS400/SS490/SS540 H-shaped steel covers different load requirements through strength gradients, combines processing convenience and economy, and is a universal solution in the construction and machinery fields.
