1. Exceptional Cost-Efficiency
Our hot-rolled black carbon steel coils feature a naturally formed dense blue-black oxide layer ("mill scale") – a byproduct of high-temperature rolling and air cooling. This intrinsic coating:
✅ Provides short-term rust protection in dry storage
✅ Reduces production costs by eliminating pickling/oiling processes
✅ Delivers unmatched value for applications where surface finish is non-critical
Vs. Pickled/Cold-Rolled Coils:
→ Eliminates post-processing → 15-20% lower cost
→ Faster lead times (ideal for urgent projects)
2. Superior Mechanical & Processing Properties
Certified Performance:
Produced to ASTM A36/A569/A1011, JIS G3101 SS400, DIN St37-2 (custom standards available)
• Optimal strength-toughness balance: Reliable yield/tensile strength + elongation
• Enhanced impact resistance: Suitable for structural applications
Manufacturing Advantages:
✓ Excellent cold-forming: Bending, stamping, deep drawing
✓ Superior weldability: Compatible with ARC/MIG/TIG welding
✓ Proven material: Widely used in construction frames and heavy machinery
3. Flexible Dimensions & Precision Tolerances
| Parameter | Specification Range |
|---|---|
| Thickness | 1.5mm – 25.4mm (1")+ (custom options) |
| Width | 600mm – 2200mm (non-standard widths available) |
| Coil Weight | 3-30 MT (max. >35 MT) |
| Inner Diameter | 508mm (20") / 610mm (24") |
Tolerance Control:
Strict compliance with ASTM/JIS/DIN standards for thickness, width, and flatness – ensuring machining consistency.
4. Strategic Value of Mill Scale
The natural oxide layer delivers triple operational benefits:
🔹 Temporary corrosion resistance: Protects coils for weeks/months in dry warehouses
🔹 Processing shield: Minimizes base metal scratches during cutting/welding
🔹 Cost driver: Reduces pricing by 18-25% vs. descaled alternatives
Core Applications
