Frequently Asked Questions

Q: What are the primary differences between DC01 and DC04 grades?

DC01 is a general-purpose cold-rolled steel, while DC04 is specifically designed for deep drawing applications, offering higher ductility and formability.

Q: Can you provide custom processing for steel coils?

Yes, we offer a one-stop service including fiber laser cutting, bending, punching, welding, and fully automatic painting based on your specifications.

Q: How is the steel protected during international shipping?

We use standard seaworthy export packing, featuring wooden pallets and plastic protection to prevent moisture and physical damage.

Q: Which international standards do your steel products comply with?

Our products are manufactured according to BS, EN, GB, AiSi, ASTM, DIN, and JIS standards to ensure global compatibility.

Q: Do you offer free samples for quality verification?

Absolutely. We provide free samples and express shipping worldwide to help you verify the material quality before placing a bulk order.
