A Uniform Cross-section H-beam (also known as I-beam) is a standardized, high-strength structural steel member with consistent cross-sectional dimensions (flange width × web height) throughout its length, engineered for universal load-bearing applications in steel frames. Manufactured with Q235B/Q355B/Q460 high-strength steel, this product features an H-shaped cross-section—composed of two parallel flanges and a central web—optimized for bending resistance, shear strength, and axial load-bearing capacity. The uniform cross-section design (standard sizes: 100×68mm-1000×300mm, customized up to 1200×400mm) ensures yield strength ≥235MPa (Q235B) to ≥460MPa (Q460), with tensile strength ≥375MPa to ≥570MPa, complying with GB/T 11263, EN 10025, and AISC 360 standards. Key features include high strength-to-weight ratio (efficiently transferring vertical and horizontal loads), standardized production for easy procurement and fabrication, and compatibility with bolted, welded, or hybrid connections. The surface is treated with hot-dip galvanizing (zinc layer thickness ≥85μm), epoxy paint, or black oxide coating, providing salt spray resistance ≥800-1200 hours (depending on treatment) and adapting to indoor, outdoor, and industrial environments. It supports universal applications in steel frames, with precise dimensional tolerance (≤±1mm for flange width/web height) ensuring seamless integration with other structural components (columns, connection plates, bracing). Professional services include material grade selection guidance, load-bearing capacity calculation, and fabrication support (cutting, drilling, welding) to meet project-specific requirements.
Uniform Cross-section H-beams are versatile structural members widely used in construction, industrial, and infrastructure projects, trusted for their reliability, standardization, and cost-effectiveness. Certified by GB/T 11263, EN 10025, and ISO 9001, they meet international steel product standards. Typical applications include primary and secondary beams in steel frame buildings (office towers, residential buildings, commercial complexes), columns and purlins in industrial workshops and warehouses, bridge structures (beam girders, cross beams), mechanical equipment bases and supports (heavy machinery, conveyor systems), and temporary structures (scaffolding, construction formwork). They are particularly suitable for projects requiring standardized, repeatable structural components—such as low-rise to high-rise buildings, light to medium industrial facilities, and general construction where uniform load distribution is required. The H-beam’s design also makes it ideal for bending-dominant scenarios (e.g., floor beams, roof rafters) and axial load applications (e.g., columns in low-rise buildings). The minimum order quantity is 10 tons for standard specifications, with flexible ordering for customized sizes. Competitive pricing based on material grade and quantity, combined with short delivery times (7-15 workdays for standard sizes), supports construction schedules. Customization options include corrosion-resistant upgrades (304/316L stainless steel H-beams) for coastal or chemical environments, fire-resistant coating (fire resistance ≥1-2 hours) for public buildings, and precision cutting/drilling for direct on-site assembly. With a monthly supply capacity of 5000 tons, the manufacturer ensures stable supply for large-scale projects, from small renovations to super-high-rise construction.
