Frequently Asked Questions (FAQ)
Q1: What is the exact open area of this 12.5mm x 30mm diamond expanded metal?
The open area depends on the strand width and pitch. For this 2.5mm wire thickness configuration, the approximate open area is around 55-60%. If you need a precise open area for filtration calculations, we can send the exact technical drawing and test data upon request.
Q2: Can this expanded metal filter panel be customized to different sizes?
Yes, we can cut the expanded metal sheet into any length and width according to your drawings. Custom shapes such as circular holes, rectangular frames, or bent edges are also available. Please provide your final dimensions and tolerances.
Q3: Does the 304 stainless steel panel withstand outdoor environments?
304 grade stainless steel offers good resistance to atmospheric corrosion and is suitable for many outdoor applications. For highly corrosive environments such as coastal areas with salt spray, we recommend using 316L or applying an additional protective coating – please consult our team for selection guidance.
Q4: What is the difference between expanded metal and wire mesh?
Expanded metal is produced by slitting and stretching a solid metal sheet, forming a diamond pattern with no joints or welds. Wire mesh is woven from wires, which allows for smaller openings but may have joints. Expanded metal offers higher rigidity and is often preferred for filtering panels and safety guards.
Q5: Can I use this product for food processing equipment?
Yes, 304 stainless steel is commonly used in food processing. The 2.5mm thickness and 12.5mm x 30mm opening provide effective screening while maintaining easy cleaning. You can select a polished or electropolished finish to meet sanitary requirements.
Q6: Do you provide samples before bulk ordering?
Yes, we can supply a small sample of approximately 200mm x 300mm or whatever size you prefer. Sample cost is usually low and we can deduct the sample fee from your first bulk order if the sample leads to a transaction.
Q7: What packing methods do you use for export?
We pack panels in wooden crates or pallets with protective plastic film and foam corners to prevent scratches and deformation during ocean freight. For small orders, strong carton boxes are used. The exact packing method is confirmed according to the panel dimensions and weight.
Q8: Is there any coating or surface finishing option available?
Yes, besides the original mill finish, we can provide PVC dipped coating, powder coating, zinc-rich painting, or stainless steel polishing. These finishes increase corrosion protection and improve appearance. Tell us your application and we will recommend the best option.
