Hot Rolled Carbon Steel Coil Products Description
Our hot rolled carbon steel coils deliver EN 10025-2 certified S275JR/S355JR grades with guaranteed yield strength (275-355 MPa). Why does chemistry matter? With controlled carbon content (0.18% max) and manganese (1.50% max), you get consistent bendability and welding performance.
Third-party tests show zero cracking in ASTM A370 bend tests even at -20°C. Our coils maintain uniform thickness tolerances (±0.15mm under EN 10051), meaning less waste when stamping automotive parts or fabricating warehouse racks. One Polish distributor reported 13% less cutting scrap versus imported coils. That's real savings on every tonne.
Factory Processing
We don't just roll steel – we precision-tune it. Our inline scale breaking and controlled cooling systems ensure decarburization stays below 0.02mm depth (tested per ASTM E1077). Every carbon steel coil gets oxide-free pickling in H₂SO₄ (concentration: 18-22%) followed by phosphating for paint adhesion. Check our surface quality: Over 95% of coils meet Class A surface (EN 10163) straight off the line. Need specific widths? Our slitters handle 900-1600mm with ±0.5mm tolerance – no more edge burrs fouling your CNC rollers.
Production Strength
1.Running 24/7 with capacity that matches your volume.
2.Two continuous casting lines feeding a 1.2 million tonne/year hot strip mill.
3.Real-time thickness control via gamma-ray gauges (±0.05mm accuracy).
Spectrometer checks every 30 minutes (ISO 17025 certified lab)
We stock 25,000 MT of ready-to-ship steel coils in EU-preferred sizes (1.5-12mm thick, ID 610/760mm). Container loading? Optimized for 25-28 MT per 40HC with moisture-barrier wrapping.
