What are the main production processes?
Hot-rolled (HR): High-temperature rolling, thicker gauges, lower cost
Cold-rolled (CR): Room-temperature rolling, thinner gauges, better surface & precision
7. What is the difference between HR and CR Q195 coils?
HR: Thickness 1.5–6.0 mm, rough surface, good ductility, low cost
CR: Thickness 0.5–3.0 mm, smooth surface, high dimensional accuracy, better formability
8. What surface treatments are available?
Black (uncoated): Mill finish
Galvanized (GI): Zinc coating for corrosion resistance
PPGI/PPGL: Prepainted for appearance & durability
9. What are the common thickness ranges?
HR: 1.5–6.0 mm
CR: 0.5–3.0 mm
10. What are the standard widths?
Common widths: 1000 mm, 1250 mm, 1500 mm; customizable per request.
