Tailored for infrastructure projects, this hot rolled structural steel features H/I beam profiles and high-strength grades Q355B (355MPa yield) and ASTM A572 Grade 50 (345MPa yield), with thickened sizes 200×100mm to 1000×300mm, web thickness 8–30mm, flange thickness 12–50mm and lengths 6–14m. Tensile strength reaches 470–650MPa, designed for highway bridges, railway supports and municipal viaducts, withstanding cyclic traffic loads, seismic forces and extreme weather. Hot rolling enhances material toughness and low-temperature impact resistance, while the H/I dual-profile design offers flexibility-H beams for main load-bearing girders, I beams for auxiliary guardrails and trusses. Excellent weldability enables secure connection to concrete piers, and compliance with national infrastructure standards makes it a durable structural material for large-scale civil engineering projects.
High Quality S235jr S355 SS400 HEA/HEB/IPE H Beam Hot Rolled Galvanized for Prefab Steel Structure
This prefab-focused galvanized H beam combines European S235jr, S355 and Japanese SS400 grades, covering HEA/HEB/IPE sections with compact sizes 100×50mm to 800×300mm, lengths 6–10m and a hot-dip galvanized finish. Yield strength 235–355MPa and tensile strength 360–630MPa, with S235jr/SS400 for light prefab frames and S355 for heavy-load prefab cores (warehouses, commercial pods). Galvanizing prevents corrosion during off-site prefabrication and on-site outdoor assembly, while hot rolling ensures dimensional consistency for seamless modular splicing-cutting construction time by 40%. The optimized HEA/HEB/IPE profiles minimize weight and transportation costs, and excellent weldability supports factory prefabrication of beam-column assemblies. Compliant with EN/JIS standards, it is a high-quality choice for modern global prefab steel structure projects.
ASTM A36 S355jr S355j2 Wide Flange Structural Welded H Beam Hot Rolled Universal Carbon Steel
This wide flange welded H beam integrates ASTM A36, S355jr and low-temperature resistant S355j2 carbon steel, with sizes 150×75mm to 900×300mm, web thickness 6–25mm, flange thickness 10–45mm and lengths 6–14m, engineered for structural projects in diverse climates. Delivering yield strength 250–355MPa and tensile strength 400–630MPa, S355j2 offers -20°C impact resistance for cold-region construction, while the welded structural design enhances joint integrity for heavy-load applications (high-rise columns, bridge decks). Hot rolling ensures uniform carbon steel properties, and the wide flange profile distributes stress evenly to prevent bending and buckling. Excellent weldability and compatibility with other steel components make it a universal choice, with ASTM/EN compliance guaranteeing consistent performance for seismic zones, cold regions and coastal areas.
Hot Rolled Steel Structural Material Q235 Q355B HEA/IPE H/I Beam Carbon Steel for Commercial & Industrial Framing
This commercial and industrial framing-focused structural steel features HEA/IPE H/I beam profiles and cost-effective Q235/Q355B carbon steel, with sizes 100×50mm to 800×300mm, web thickness 4–22mm, flange thickness 6–40mm and lengths 6–12m. Delivering tensile strength 375–630MPa, Q235 suits light commercial framing (retail stores, office mezzanines) while Q355B excels in industrial plant frames and logistics warehouse supports. The HEA/IPE dual-section design optimizes strength-to-weight ratio-HEA for wide-flange load-bearing, IPE for narrow-flange auxiliary framing-minimizing material costs and maximizing interior space. Hot rolling ensures precise dimensional accuracy and excellent workability for on-site cutting and welding, with GB/T compliance making it a cost-efficient, versatile structural material for mixed commercial and industrial construction projects.
Hot Rolled Steel Structural Material Q235 Q355B ASTM A36 H/I Beam Carbon Steel for General Construction
This hot rolled structural steel features dual H/ I beam profiles and multi-grade carbon steel-Q235 (235MPa yield), Q355B (355MPa yield) and ASTM A36 (250MPa yield)-with sizes ranging 100×50mm to 1000×300mm (height×flange width), web thickness 4–28mm, flange thickness 6–50mm and customizable lengths 6–14m. Delivering tensile strength 375–630MPa, it adapts to general construction needs: residential frames, commercial mezzanines and light industrial supports. Hot rolling ensures uniform grain structure, precise dimensional accuracy and excellent weldability for on-site fabrication, with Q235/ASTM A36 for cost-efficient light loads and Q355B for heavy-duty structural components. Compliant with GB/T and ASTM standards, it is a versatile, all-in-one structural material for contractors seeking mixed-profile steel for diverse construction scenarios.
