Hot Products
High-Quality Hot-Rolled Steel Coils from China's Leading Suppliers and Factory for Superior Strength and Durability
The rapid cooling phase locks in these mechanical characteristics, while the natural oxidation forms a protective mill scale layer. Post-rolling, our coils undergo rigorous inline inspection using laser gauges to ensure compliance with ISO 4996:2014 EN standards, guaranteeing thickness uniformity (±0.1 mm) and flatness (≤3 I-units).
Applications
Structural frameworks (I-beams, channels), truck chassis, agricultural equipment, and pressure vessel manufacturing. Its weldability and machinability make it suitable for CNC cutting and stamping operations.
Key Advantages
Cost Efficiency
Reduced energy consumption during production lowers per-ton costs by 15–20% versus cold-rolled alternatives.
Scalability
Customizable widths (600–2,000 mm) and thicknesses (1.2–25 mm) accommodate bridge construction to precision machinery.
Durability
Yield strength ranges from 235 MPa (mild grades) to 550 MPa (high-strength low-alloy variants), outperforming ASTM A36 benchmarks.
