🔹 FAQ
Q1: What is micro expanded mesh used for?
It’s widely used in industrial filters, sound-absorbing panels, electronic shielding, and micro-ventilation systems, where precision and uniformity are critical.
Q2: How small can the mesh openings be?
The smallest LWD (Long Way of Diamond) can reach 0.2 mm, depending on material and thickness.
Q3: Which materials are best for micro expanded mesh?
Stainless steel and aluminum are most common for durability and corrosion resistance, while copper and nickel are used for conductivity and shielding.
Q4: Can you make custom patterns or apertures?
Yes, we provide OEM & ODM customization for mesh size, pattern, coating, and sheet thickness.
Q5: Is micro expanded mesh stronger than woven wire mesh?
Yes — since it’s made from a single solid sheet without welds, it maintains higher structural integrity and resistance to tearing.
Q6: What is the maximum sheet size?
Standard up to 1200 mm width × 2400 mm length, and rolls can be supplied upon request.
Q7: What’s your minimum order quantity (MOQ)?
Usually 100 sheets or 50 sqm, depending on material and thickness.
Q8: What surface treatments are available?
We offer degreasing, anodizing, powder coating, and chemical passivation for corrosion and wear protection.
