Anping County Boli Hardware Wiremesh Products Factory, established in 1998 with an annual export value of US$5-10 million, proudly presents our premium Perforated Metal Mesh made from 316 Stainless Steel. This product is specifically engineered for food processing equipment, combining high corrosion resistance, precise slot holes, and an optimal 40% open area to ensure efficient filtration and material flow. As a trusted manufacturer serving markets across North America, South America, Europe, Asia, and Africa, we deliver consistent quality that meets the rigorous demands of the food industry.
Our 1.5mm thick perforated mesh with 3mm slot holes offers a robust balance between strength and permeability. The 316 stainless steel construction provides superior resistance to acidic foods, cleaning chemicals, and high-temperature washdowns, making it ideal for sieves, strainers, conveyor belts, and ventilation panels in food processing lines. The 40% open area maximizes throughput while maintaining structural integrity, reducing downtime and improving production efficiency.
Key Features & Technical Specifications
- Material: 316 Stainless Steel (1.4401) – excellent pitting and crevice corrosion resistance, suitable for food contact.
- Thickness: 1.5mm ±0.05mm – durable enough for heavy-duty industrial use yet malleable for custom fabrication.
- Hole Shape: Slot (rectangular) – provides directional flow and reduces clogging compared to round holes.
- Hole Size: 3mm (slot width) – allows precise particle separation while maintaining high flow capacity.
- Open Area: 40% – optimized for applications requiring fast drainage or aeration without sacrificing strength.
- Perforation Pattern: Staggered or straight row (customizable) – enhances structural stability and uniform distribution.
- Surface Finish: Mill finish, bright annealed, or pickled & passivated – optional to meet hygiene standards.
- Sheet Size: Standard 1m x 2m, or custom sizes up to 1.5m x 3m (available upon request).

Frequently Asked Questions (FAQ)
-
Q: Is this perforated mesh food-grade safe?
A: Yes. 316 stainless steel is a common food-grade material, resistant to corrosion from acidic foods and cleaning agents. Our mesh is produced in a controlled environment to avoid contamination. -
Q: Can you customize the slot length or pattern?
A: Absolutely. We offer customizable slot lengths (e.g., 10mm, 20mm, 50mm) and hole patterns (staggered, straight, or hexagonal). Please provide your drawing or specifications for a quote. -
Q: What is the maximum sheet size you can produce?
A: Our standard sheet size is 1m × 2m, but we can produce up to 1.5m × 3m for this thickness. Larger sizes may require special handling; contact us for feasibility. -
Q: How do you ensure the open area is exactly 40%?
A: We use precision CNC punching machines that maintain tight tolerances. The 40% open area is calculated based on the hole size and pitch. We can adjust the pattern to achieve different open areas if needed. -
Q: What surface finish do you recommend for food processing?
A: For direct food contact, we recommend a bright annealed or pickled & passivated finish to reduce surface roughness and enhance corrosion resistance. Mill finish is suitable for non-contact applications. -
Q: How long is the lead time for a typical order?
A: For standard sizes and finishes, lead time is 7–15 working days. Custom orders may take 15–25 days depending on complexity. We ship from ports like Tianjin, Qingdao, Shanghai, and Foshan. -
Q: Can you provide samples before bulk order?
A: Yes, we offer free samples (A4 size) for quality evaluation. Shipping cost is the buyer's responsibility. Contact our sales team to arrange. -
Q: Do you have any certifications for food industry standards?
A: While we do not have specific food-grade certifications mentioned here, our production process follows strict quality control procedures. We can provide material test certificates (MTC) upon request. Many clients use our mesh in FDA-compliant equipment after their own validation.
