H-beam steel offers superior strength, structural stability and material efficiency with its optimised I-shaped cross-section. Widely used in skyscrapers, bridges, industrial frameworks and heavy machinery bases, it provides robust support under extreme loads and seismic forces. Available in carbon steel (e.g. ASTM A36/JIS SS400) for cost-effective general construction or high-strength low-alloy grades (e.g. Q355B/ASTM A572) for demanding environments such as offshore platforms and mining equipment. Compliant with international standards (EN 10025/GB/T 11263), it offers excellent weldability, ease of assembly and corrosion resistant options (galvanised/weathering steel).
