Frequently Asked Questions (FAQ)
Q1: What is the minimum order quantity (MOQ) for this mesh?
A: MOQ is typically 100 sheets per size, but we can accommodate smaller orders for sample testing. Please contact us for details.
Q2: Can I get a custom hole pattern or size?
A: Yes, we offer full customization. You can specify hole diameter, pitch, shape (round, square, slotted), and overall sheet dimensions. Our engineering team will review your design and provide a quotation.
Q3: What is the tolerance for hole diameter and thickness?
A: Standard tolerance is ±0.02mm for both thickness and hole diameter. Tighter tolerances are available upon request, subject to feasibility.
Q4: How does this mesh compare to woven wire mesh for speaker grills?
