Ordinary Surface
Galvanized Surface (thickness of the hot-dip galvanizing ≥ 85μm, life span of 15-20 years),
Steel Structure Buildings: Use in columns, beams and frames which build up in the commercial and residential building.
Industrial Plants & Warehouses: Fabric buildings for factories, manufacturing equipment and more.
Bridges & Infrastructure: For use in highway, pedestrian bridges or infrastructure projects.
High-Rise & Large-Span Structures: Recommended for sports stadiums, airports, exhibition halls and other large-span buildings.
Machinery Support: Because of its stability, it is ideal for industrial machinery and work platforms.
Prefabricated Structures:They are usually employed in the system of modular steel building.
1) Have branch offices in the United States and Guatemala, and can provide Spanish-language support.
2) 5000 TONS H Beam in stock in the warehouse.
3) Comprehensive quality inspection is conducted on the goods before they leave the factory.
Padding: To avoid surface scratches or the "strangulation marks" of the straps, a small portion of rubber or heavy duty foam is inserted at the interface of the beams and the point of strapping.
Anti-Sliding: The alignment of the beams in a bundle should not be compromised. For shorter lengths, two-line bundling is adequate, for longer pieces, extra support points prevent bending and/or sliding.
Indoor Storage/Transport: If the steel is pre-painted or otherwise finished, it must be wrapped in a moisture barrier, such as a plastic film or kraft paper.
Outdoor Transport: For rail, oversea, bulk transport, double-layer waterproof tarpaulins are available as a standard to keep away from wet, salty environment of sea.
Q1: What standards does Q355B comply with?
A: Q355B complies with the Chinese standard GB/T 1591 and meets international structural steel requirements.
Q2: Can you provide Mill Test Certificates (MTC)?
A: Yes, Mill Test Certificates are provided for each batch. Third-party inspection such as SGS or BV is also available upon request.
Q3: What are your packaging and delivery methods?
A: H Beams are bundled with steel straps, supported by wooden spacers, and optionally wrapped for protection. Shipment is available via container or bulk vessel with FOB, CFR, CIF, or EXW terms.
Q4: What is the delivery time?
A: Stock: 5–10 days
Production: 15–30 days depending on order quantity and specifications
Q5: Do you support customization?
A: Yes, we support customized dimensions, lengths, and project-based fabrication according to drawings and requirements.
