Frequently Asked Questions

What are the standard thickness and width ranges for hot rolled coils?

Standard hot rolled coils typically have a thickness ranging from 1.5mm to 25mm and a width ranging from 600mm to 2000mm. Custom dimensions may vary based on application needs.

How do carbon steel, alloy steel, and stainless steel hot coils differ?

Carbon steel coils are highly cost-effective and strong; alloy steel coils contain added manganese and silicon for enhanced strength and wear resistance; stainless steel coils contain chromium and nickel for superior corrosion resistance in challenging environments.

What are the primary applications of hot rolled steel coils?

They are extensively utilized in key industries including construction (for steel structures and bridges), automotive (for chassis and car bodies), machinery manufacturing, and the chemical/food sectors (for corrosion-resistant containers).

What advantages do pickled hot rolled coils offer?

Pickled coils are treated with acid to remove the surface oxide scale. This results in a cleaner, smoother finish that improves the overall surface quality for subsequent fabrication or processing steps.

What industry standards govern the quality of these hot rolled coils?

All products comply strictly with leading global and regional standards, including ASTM, GB/T, and JIS, ensuring precise control over carbon content, elongation properties, and surface defect thresholds.
