Frequently Asked Questions (FAQ)

Q: Can this sheet be used outdoors?
A: Yes, but we recommend applying a protective coating (e.g., paint, powder coating, or galvanizing) to prevent rust. The mild steel base is durable but requires surface treatment for extended outdoor exposure.
Q: What is the standard sheet size?
A: Our standard size is 1000mm x 2000mm. Custom dimensions up to 1500mm x 3000mm are available per request. Please specify your requirements when ordering.
Q: How is the hole pattern arranged?
A: The holes are arranged in a staggered (45-degree) pattern to maximize strength and open area. The standard pitch (center-to-center) is 10.5mm for 6mm holes, achieving 30% open area. Other patterns can be customized.
Q: Is this product suitable for food-grade filtration?
A: This heavy-duty mild steel sheet is not specifically designed for food contact. However, it can be used in filtration systems for non-food particles. For food-grade applications, we recommend stainless steel perforated sheets.
Q: What is the minimum order quantity (MOQ)?
A: Our MOQ is typically 50 sheets for standard sizes. For custom sizes or special finishes, MOQ may vary. Small trial orders are accepted upon negotiation.
Q: Can you provide samples before bulk order?
A: Yes, samples (e.g., 300mm x 300mm) are available. Please contact us to arrange sample shipment. The cost of the sample is free, but shipping is at your expense.
Q: How long does production take?
A: For standard sizes and plain finish, production takes 7-15 working days after deposit confirmation. Custom orders may require 15-25 working days depending on complexity.
Q: What packing method do you use to prevent damage?
A: Sheets are packed in wooden crates or steel pallets with protective layers (plastic film, foam, or cardboard) to avoid scratches and bending during transit. Each bundle is strapped securely.
