Technical FAQ

Q: How do you ensure the width tolerance of narrow strips?

A: We utilize high-precision CNC slitting lines that maintain a tolerance of ±0.02mm. This is critical for clients using automated roll-forming or stamping machines.

Q: Do you offer different inner diameter (ID) options for the coils?

A: Yes, common ID options include 508mm and 610mm. We can also provide customized small-coil packaging for specialized industrial needs.
