Steel Hot Rolled Cold Rolled Mild H/I Section Beam For Construction
Low alloy steel H beam is a section of optimized area, high strength to weight ratio of economic section profile is more reasonable, so named because of its cross section and English letter "H" is the same. Due to various parts of low alloy H steel beam are arranged at right angles, so the low alloy H steel beam in each direction has bending ability, simple construction, has the advantages of saving cost and light weight structure, has been widely used.
Structural steel H/I beams are load-bearing components manufactured through either hot rolling (heated above recrystallization temperature) or cold rolling (processed at room temperature). The mild steel composition (typically 0.05%-0.25% carbon content) ensures optimal weldability and formability while maintaining structural integrity.
Hot Rolled Beams
Exhibit superior yield strength (235-355MPa) with slight dimensional variations, ideal for heavy construction where precision is secondary to load capacity.
Cold Rolled Beams
Provide enhanced surface finish (Ra≤3.2μm) and tighter tolerances (±0.5mm), suitable for architectural applications requiring precise fitment.
Standardized per ASTM A36 (US) or GB/T 706 (China), these I-shaped and H-shaped cross-sections efficiently distribute vertical/horizontal loads in building frames, bridges, and industrial structures.

1.Q: What's the difference between hot rolled and cold rolled H/I beams?
A:
☆Hot Rolled Beams: Produced at high temperatures (≈1200°C), offering higher load capacity but rougher surface finish. Tolerances: ±2mm on web thickness.
☆Cold Rolled Beams: Processed at room temperature for precise dimensions (±0.5mm) and smoother surfaces (Ra≤3.2μm), but with 10-15% lower ductility.
2.Q: Which standard specifications do your beams comply with?
A: Our beams meet:
ASTM A36 (General construction)
EN 10025 S235JR (European standard)
JIS G3101 SS400 (Japanese standard)
GB/T 706 (Chinese standard)
3.Q: What are the typical applications for each type?
A:
☆ Hot Rolled: Bridge girders, warehouse frames, heavy industrial structures (Max span: 30m for standard sections).
☆Cold Rolled: Prefab buildings, architectural elements, modular construction where precision matters.
4.Q: Can I get custom lengths or special coatings?
A: Yes! We provide:
Custom cutting (6m to 18m lengths)
Anti-corrosion treatments (Galvanizing, epoxy coating)
Fire-resistant coatings (Up to R120 rating)
5.Q: How does pricing compare between the two types?
A: Cold rolled beams typically cost 15-20% more due to additional processing, but save on post-fabrication machining costs.
