Describe Product

Mục lục

I-beam is a structural steel with an I-shaped cross-section, consisting of a vertical web connecting two horizontal flanges. Thanks to its optimized material distribution, I-beam delivers exceptional bending and compression resistance, achieving a high strength-to-weight ratio that reduces construction costs. Typically manufactured from carbon steel (SS400, A36) or low-alloy steel (A572 Gr.50, S355JR), it is widely used for factory support beams, bridge girders, high-rise building columns, and industrial machinery frames.

I. FEATURES

Exceptional load-bearing capacity: With optimized force distribution (flanges resist bending, web resists shear), I-beams support extreme loads up to 500 tons over 30m spans, ideal for cranes and heavy factories.
Economic efficiency in construction: Saves costs versus concrete through lightweight properties, reduced foundation materials, and rapid bolted modular assembly.
Easy fabrication and installation: Optimal factory prefabrication (hole cutting, end-plate welding), and tool-free site assembly reduces labor cost and waste versus cast-in-place concrete.
Versatile applications: Widely used in civil/industrial construction, bridges, plants, shipbuilding, and heavy-load structures due to unmatched versatility.
Superior stability and bending resistance: The I-shape concentrates material at the flanges (maximum bending stress zones), creating higher moment of inertia, and limiting deflection.
Wide range of sizes and steel grades: Manufactured to international standards (JIS, ASTM, EN, etc), I-beams are available in a wide range of sizes and steel grades to meet diverse project requirements.
