FAQs of Special-Shaped Steel

What steel grades do you offer for special-shaped profiles?

We work with a wide range of grades including carbon steel (45#, Q235, Q275), alloy steel (40Cr, 20Cr, 42CrMo), and stainless steel (304, 316). Custom grades are available on request.

What is your minimum order quantity?

Our MOQ is 2 tons per order. For standard profiles, we can accommodate smaller trial orders. Custom profiles may require larger initial quantities depending on die setup.

What tolerances can you achieve?

Cold-drawn special-shaped steel typically achieves dimensional tolerances of ±0.02mm. For ultra-precision requirements, grinding can bring tolerances to ±0.005mm.

Can you produce based on our drawings?

Yes. Share your technical drawings or samples, and our engineering team will review feasibility, recommend material grades, and provide a quotation within 24 hours.


What surface treatments are available?

Standard finish is cold-drawn (bright). Optional treatments include grinding, polishing, phosphating, and anti-rust oil coating depending on your application needs.

What are your typical lead times?

Stock grades ship within 7 days. Custom profiles typically take 15–25 days depending on order volume and die availability. Rush orders are available upon request.

Do you provide samples?

Yes. We can supply small samples for quality inspection before bulk orders. Sample costs and shipping are charged separately.
