Frequently Asked Questions
Q1: What is the difference between cold drawn and hot rolled stainless steel rods?
A: Cold drawn rods have tighter dimensional tolerances, a smoother surface finish, and higher strength due to work hardening. They are ideal for precision applications, while hot rolled rods are more economical for larger sizes where surface finish is less critical.
Q2: Can you provide rods with a diameter larger than 50mm?
A: Yes, we can produce custom diameters up to 200mm upon request. Please contact our sales team with your specific requirements for lead time and pricing.
Q3: Are these rods suitable for food contact applications?
A: Yes, 304 stainless steel is generally food-grade and widely used in food processing equipment. However, we recommend confirming compliance with local regulations for your specific application.
Q4: What is the typical lead time for orders?
A: For standard diameters (6-50mm), lead time is typically 7-15 days depending on quantity. Custom sizes or special finishes may require additional time. We can provide a precise schedule upon inquiry.
Q5: Do you offer samples before bulk ordering?
A: Yes, we provide free samples for evaluation, with the buyer covering shipping costs. Sample lead time is about 3-5 days after confirmation.
Q6: What packaging options are available?
A: Standard packaging includes bundles with steel straps, wooden crates for fragile finishes, or waterproof wrapping for overseas containers. Custom packaging is available upon request.
Q7: How do you ensure the quality of the rods?
A: Our ISO9001 quality management system includes incoming material inspection, in-process dimensional checks, and final surface finish testing. Each batch is traceable and accompanied by a mill test certificate.
Q8: Can you supply rods with a bright or mirror finish?
A: Yes, we offer various polishing grades including bright (Ra 0.4μm) and mirror (Ra 0.1μm) finishes. Please specify your requirement when ordering.
