Frequently Asked Questions (FAQ)
-
Q: What is the exact material grade of this perforated sheet?
A: The sheet is made from 304 stainless steel (UNS S30400), which contains 18-20% chromium and 8-10.5% nickel, offering excellent corrosion resistance and formability. -
Q: Can you provide sheets with different hole patterns, such as square or slotted holes?
A: Yes, we can produce custom hole shapes (round, square, slotted, hexagonal) and patterns (staggered, straight) according to your drawings or samples. Please contact us with your requirements. -
Q: What is the maximum sheet size you can produce?
A: Our standard maximum sheet size is 1500×3000 mm, but we can also offer larger sizes up to 2000×4000 mm depending on the thickness and hole pattern. Custom sizes are available. -
Q: How do you ensure the sheet is free from burrs?
A: After punching, we perform deburring and edge finishing processes. Standard sheets are supplied with minimal burrs. For applications requiring very smooth edges, we offer additional deburring or brushing services. -
Q: Is this perforated sheet suitable for outdoor use in coastal areas?
A: 304 stainless steel has good resistance to saltwater corrosion, but for severe marine environments we recommend 316 stainless steel. We can supply 316 material upon request. -
Q: What is the typical lead time for a standard order?

Q: Can you cut the sheets to my exact dimensions?
A: Yes, we offer precision cutting (shearing, laser cutting) to your specified dimensions, with tolerances as tight as ±0.5 mm. Please provide a cutting list or drawing. -
Q: Do you offer samples before bulk ordering?
A: Absolutely. We can provide small samples (e.g., 200×200 mm) for evaluation. Sample cost is charged and will be deducted from the first bulk order. Shipping cost is on the buyer.
