Frequently Asked Questions

Q: What materials are available for the grille?
A: We offer stainless steel, cold-rolled steel, and other metals. The choice depends on your required strength, corrosion resistance, and budget. Stainless steel provides excellent corrosion resistance, while cold-rolled steel is more cost-effective with proper coating.
Q: Can the hole pattern be customized to specific acoustic requirements?
A: Yes, we can adjust the hole diameter, spacing, and shape (round, square, hexagonal, etc.) to achieve the desired open area ratio and acoustic transparency. Our engineers can help you optimize the design.
Q: How long does the black oxide coating last?
A: The black oxide coating is a durable conversion coating that provides excellent corrosion resistance for indoor and most outdoor environments. Under normal conditions, it maintains its appearance for years. For extreme environments, additional protective layers can be applied.
Q: What is the minimum order quantity (MOQ)?
A: Our MOQ varies by size and complexity. For standard sizes, MOQ is typically 500 pieces. For custom designs, please contact us for a specific quote. We also offer samples for testing.
Q: Do you provide samples before bulk order?
A: Yes, we can provide samples at a reasonable cost. The sample fee will be deducted from your first bulk order. We encourage customers to test the grille for fit, acoustic performance, and durability.
Q: How does the grille affect sound quality?
A: The grille is designed to minimize acoustic interference. By carefully selecting the open area ratio (typically 40-60%), we ensure that sound waves pass through with minimal attenuation. The black oxide coating does not negatively impact sound.
Q: Can you provide custom packaging?
A: Yes, we offer custom packaging options such as individual bubble bags, cardboard separators, or branded boxes to protect the grilles during shipping and enhance your brand presentation.
Q: What are the shipping options?
A: We ship from major Chinese ports (Tianjin, Qingdao, Shanghai, Foshan) via sea or air. We can also arrange door-to-door delivery via express couriers for small orders. Lead times are typically 15-25 days after order confirmation, depending on quantity.
