Frequently Asked Questions (FAQ)
Q1: Can this mesh be used for outdoor speaker grilles?
Yes, the 304 stainless steel is highly resistant to rust and corrosion, making it suitable for outdoor automotive applications like truck speaker pods or marine audio systems. However, we recommend a protective coating for extreme saltwater environments.
Q2: What is the tolerance on hole diameter and thickness?
Our standard tolerance is ±0.05mm for hole diameter and ±0.03mm for thickness. We can achieve tighter tolerances if required for your project.
Q3: How do you package the mesh to prevent damage during shipping?
Sheets are interleaved with kraft paper or foam, then packed in sturdy wooden crates. Coils are wrapped with protective film and secured on pallets. For fragile finishes, we use additional cushioning.
Q4: Can you provide custom hole patterns (e.g., slot or diamond)?
Absolutely. We have a wide range of die sets and can produce custom patterns upon request. Please contact us with your specific pattern drawing or specification.
Q5: Is this mesh available in coil form for automated production?
Yes, we offer the mesh in coils (up to 500kg) with inner diameter options of 300mm, 400mm, or 500mm. Coils are ideal for high-volume stamping or roll forming.
Q6: What surface treatments do you offer?
Standard options include mill finish, brushed (hairline), powder coating (any RAL color), and anodizing. We can also apply anti-fingerprint coating for a cleaner appearance.
Q7: Can you cut the mesh to exact dimensions for my speaker grille?
Yes, we offer precision laser cutting or shearing to your specified dimensions. We also provide deburring and edge rounding to ensure safe handling.
Q8: How do you ensure the open area is exactly 45%?
Our perforation process uses CNC-controlled presses with calibrated dies. Every production batch is sampled and measured using a digital area meter to verify the open area percentage. We maintain a strict quality assurance protocol.
