Excellent weldability enables secure connection to concrete piers and steel reinforcements, and the mild carbon steel composition ensures cost-efficiency for large-scale infrastructure projects. Compliant with civil engineering standards, it is a durable and economical structural choice for municipal bridge and highway construction.
High Quality ASTM A36 S235jr S355 SS400 HEA/HEB H Beam Hot Rolled Galvanized for Prefab Steel Structure
This multi-grade galvanized H beam combines ASTM A36, S235jr, S355, SS400 steel, focusing on HEA/HEB wide flange sections with sizes 150×150mm to 800×300mm and lengths 6–10m, ideal for prefab steel structure buildings. Yield strength ranges 235–355MPa, with tensile strength 360–650MPa-S235jr/SS400 for light prefab frames, S355/ASTM A36 for heavy-load prefab cores (warehouses, industrial workshops). Hot-dip galvanizing ensures corrosion resistance for off-site prefabrication and on-site outdoor assembly, while hot rolling guarantees dimensional consistency for seamless modular splicing (reducing construction time by 40%). The wide flange HEA/HEB profile maximizes strength-to-weight ratio, minimizing transportation and foundation costs. Compliant with ASTM/EN/JIS standards, it is a high-quality, versatile structural material for global prefab steel structure projects.
High Quality ASTM A572 Grade 50 Hot Rolled Galvanized Carbon Steel H Beam for Heavy Industrial Steel Structure
This heavy-duty H beam is made of ASTM A572 Grade 50 high-strength carbon steel, with large sizes 250×125mm to 1000×300mm, web thickness 10–30mm, flange thickness 15–50mm, and lengths 6–14m, finished with hot-rolled galvanizing. Delivering 345MPa yield strength and 450–650MPa tensile strength, it is engineered for heavy industrial steel structures: factory frames, crane runways, and heavy equipment bases, withstanding dynamic equipment vibrations and ultra-heavy cargo loads (up to 60 tons per square meter). Galvanizing provides corrosion protection for industrial workshop environments (with dust, moisture, and mild chemicals), while hot rolling enhances material toughness and fatigue resistance. The wide flange design optimizes load distribution, and excellent weldability enables secure anchoring to concrete floors. Compliant with ASTM industrial standards, it is a premium structural material for heavy manufacturing and logistics industrial construction.
H Shape Beam Q235 Q345 ASTM A283 Mild Carbon Steel for Commercial Building Steel Structure
Designed for modern commercial building steel structures, this H shape beam features Q235/Q345 mild carbon steel and ASTM A283 compliance, with versatile sizes 120×60mm to 800×300mm, web thickness 5–20mm, flange thickness 8–35mm, and lengths 6–12m. Delivering tensile strength 375–630MPa, it adapts to all commercial building components: shopping mall frames, office building mezzanines, and hotel core columns. Q235 offers cost-efficiency for light-load secondary structures, while Q345 provides high strength for main load-bearing parts, balancing project budget and structural performance. The H cross-section ensures uniform load distribution, supporting long spans to maximize interior commercial space, and excellent weldability accelerates modular prefabrication and on-site assembly. The mild carbon steel composition is easy to process and customize, making it a practical core material for diverse commercial building steel structure projects.
