Frequently Asked Questions (FAQ)
-
Q: What is the typical sound absorption coefficient (NRC) of this mesh?
A: The NRC depends on the hole pattern, backing material, and mounting method. For a 40% open area mesh with acoustic backing, the NRC can range from 0.7 to 0.9. We recommend testing with your specific configuration. -
Q: Can the mesh be used outdoors?
A: Yes, 304 stainless steel has good weather resistance. However, for coastal areas or high-corrosion environments, we can supply 316L grade upon request. -
Q: What is the minimum order quantity (MOQ)?
A: MOQ for standard sizes is 50 sheets. For custom patterns, MOQ may be higher. Contact our sales team for details. -
Q: How long does it take to produce a custom order?
A: Typically 15–20 working days after sample approval, depending on complexity and quantity. -
Q: Do you provide free samples?
A: Yes, we can provide small samples (e.g., 200x200mm) for evaluation. Shipping cost is negotiable. -
Q: Can the mesh be easily cut to size on-site?
A: Yes, 0.5mm stainless steel can be cut with standard tin snips or shears. For large quantities, we can pre-cut to exact dimensions. -
Q: Is the mesh suitable for food contact applications?
A: 304 stainless steel is food-grade, but the etched surface may have microscopic crevices. For direct food contact, we recommend polished or electropolished finish. -
Q: What payment terms do you accept?
A: We accept T/T, L/C, and for long-term partners, open account terms are negotiable.
