Our I-beams are forged from high-strength carbon steel (Q235B, Q355B, A36, etc.) and alloy steel, featuring the iconic "I" cross-section that balances exceptional load-bearing capacity, bending resistance, and structural stability. Available in hot-rolled (HR) and welded types—HR for heavy-duty infrastructure (building frames, bridges, crane beams) and welded for customized dimensions in industrial plants. Compliant with ASTM A36, BS 4 part 1, and GB/T 706 standards, each batch comes with MTC, supporting custom lengths and surface treatments (black oxide, galvanized).

Billets are heated to 1100-1200℃ in walking beam furnaces, then rolled through multi-pass universal rolling mills to shape the "I" profile, with eddy current flaw detectors checking internal quality. For welded I-beams, steel plates are cut to size via CNC plasma cutters, then welded into the I-shape using submerged arc welding (SAW) for strong joints. Post-production, beams undergo straightening, length cutting, and surface inspection—with laser dimension gauges ensuring cross-sectional accuracy. Full process tracing guarantees structural reliability.

Each I-beam undergoes strict testing: ultrasonic flaw detection, mechanical property tests (yield strength ≥235MPa), and chemical composition analysis (S/P content ≤0.05%). Certified with ISO 9001, CE, and Mill Test Reports (MTR). Random sampling and third-party inspections (SGS/BV) accepted.

Secure packaging with steel strapping and waterproof wrapping to prevent corrosion. Bulk loading or containerized shipping (20GP/40HQ) with optimized space utilization. On-time delivery guaranteed, supported by our logistics partners for FOB/CIF/DAP terms. Loading videos and packing lists provided.
