❓ Frequently Asked Questions
Q1: What is the main difference between 304 and 316 stainless steel?
316 stainless steel contains molybdenum, which significantly enhances its resistance to corrosion, especially in chloride-rich or marine environments, whereas 304 is the standard general-purpose grade.
Q2: Can you provide custom sizes or slitting for stainless steel sheets?
Yes, we provide high-precision slitting and cut-to-length services to meet specific width and length requirements, with widths as narrow as 22mm.
Q3: What types of surface finishes do you offer?
We offer a wide range of finishes including 2B (matte), BA (mirror-like), No.4 (brushed), HL (hairline), as well as decorative options like PVD color coating and etching.
Q4: Is a Mill Test Certificate (MTC) provided with the materials?
Yes, all shipments include a Mill Test Certificate (MTC) according to EN 10204 3.1, ensuring full traceability and material compliance.
Q5: How is the material protected during international shipping?
We use export-standard seaworthy packaging including PE protective film, waterproof paper, and fumigation-free pallets with steel strapping to ensure the material arrives in perfect condition.
Q6: What is the lead time for standard orders?
Lead times depend on the specific grade and finish required. Standard stocked items can often be processed and dispatched quickly, while custom decorative finishes may require additional time.
