This H-beam combines excellent structural performance with cost-effectiveness, making it a top choice for heavy-duty construction and engineering projects. With an annual export value exceeding US$50 million, our commitment to quality and reliability is backed by ISO9001 certification and a professional team of 51-100 employees.
Product Overview
The H-beam 300x300x10x15mm is a hot-rolled steel section manufactured to ASTM A36 standard. Its dimensions (300mm height, 300mm flange width, 10mm web thickness, 15mm flange thickness) provide outstanding load-bearing capacity and stability. Ideal for beams, columns, and frames in buildings, bridges, and industrial structures, this product meets the rigorous demands of modern construction while offering excellent weldability and machinability.
Key Features & Technical Specifications
- High Strength & Durability: ASTM A36 steel ensures a minimum yield strength of 250 MPa, suitable for structural applications requiring reliable performance.
- Precise Dimensions: Rolled to tight tolerances (±0.5mm on height/flange, ±0.3mm on thickness) for easy assembly and consistent quality.
- Excellent Weldability: Low carbon content (max 0.26%) allows for straightforward welding without preheat or post-weld heat treatment.
- Versatile Applications: Used in building frames, bridge girders, industrial racks, shipbuilding, and transmission towers.
- Customizable Length: Standard lengths 6m, 9m, 12m; other lengths available upon request.
- Surface Treatment Options: Black (mill finish), painted (custom RAL colors), or hot-dip galvanized for corrosion resistance.
- Traceability: Each bundle is marked with mill test certificates (MTC) and heat numbers for full traceability.
