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.
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.
Cold-drawn special-shaped steel typically achieves dimensional tolerances of ±0.02mm. For ultra-precision requirements, grinding can bring tolerances to ±0.005mm.
Yes. Share your technical drawings or samples, and our engineering team will review feasibility, recommend material grades, and provide a quotation within 24 hours.
Standard finish is cold-drawn (bright). Optional treatments include grinding, polishing, phosphating, and anti-rust oil coating depending on your application needs.
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.
