Frequently Asked Questions

Q1: What is the difference between cold rolled and hot rolled stainless steel?
Cold rolled 304 stainless steel has a smoother surface, tighter dimensional tolerances, and higher strength compared to hot rolled. It is ideal for applications requiring precise hole patterns and a clean appearance.
Q2: Can the hole diameter or pitch be customized?
Yes, we offer customization for hole sizes, pitch, tube diameter, and wall thickness. Please provide your drawing or specifications for a tailored solution.
Q3: What does surface passivation do?
Passivation removes free iron and surface contaminants from the stainless steel, enhancing the natural chromium oxide layer. This improves corrosion resistance and prevents rust formation.
Q4: Is this tube suitable for outdoor use?
Yes, 304 stainless steel with passivation offers good resistance to atmospheric corrosion. For extreme coastal or chemical environments, we recommend evaluating the specific conditions.
Q5: What is the maximum length you can produce?
Standard lengths go up to 6 meters. Longer lengths can be produced upon request, subject to shipping and handling constraints.
Q6: How do you package the tubes for export?
Tubes are bundled with protective wrapping, secured with steel straps, and packed in wooden crates or pallets to prevent damage during transit.
Q7: Do you provide samples before bulk order?
Yes, we can provide samples (cost may apply) for evaluation. Contact our sales team to arrange.
Q8: What is the typical lead time?
For standard sizes, lead time is 15–20 working days after order confirmation. Custom orders may require additional time depending on complexity.
