I-beam steel offers exceptional strength and structural efficiency with its iconic I-shaped profile, optimising strength-to-weight ratios. Manufactured from carbon steel (e.g. ASTM A36, SS400) or high-strength low-alloy steel (e.g. ASTM A572, Q355B), it's ideal for skyscrapers, bridges, industrial frameworks and heavy machinery bases, ensuring stability under dynamic loads and seismic forces. Compliant with ASTM/EN/JIS standards, it offers easy welding/bolting, corrosion-resistant coatings (galvanised/painted) and cost-effective fabrication for rapid assembly.
