Since 1998, Anping County Boli Hardware Wiremesh Products Factory has been a trusted manufacturer of precision wire mesh products. Our Durable Circular Filter Mesh made from 304 stainless steel is engineered for demanding filtration applications. With opening sizes ranging from 0.5mm to 3mm and diameters from 100mm to 500mm, each piece is supplied with a Mill Test Report ensuring material traceability and quality. This product combines strength, corrosion resistance, and dimensional accuracy to meet rigorous industrial standards.
The mesh is woven from high-quality 304 stainless steel wire, offering excellent resistance to oxidation, chemicals, and high temperatures. Its circular shape is precisely cut to your specified diameter, making it ideal for inline filtration, liquid-solid separation, and air/gas screening. The uniform opening size guarantees consistent filtration performance, while the durable construction withstands repeated cleaning and heavy use.

Frequently Asked Questions
Q1: What is the difference between plain weave and twill weave for this filter mesh?
Plain weave provides a simple over-under pattern with uniform openings, suitable for general filtration. Twill weave offers a tighter structure with higher strength and is often used for finer openings or when additional durability is needed. Both are available upon request.
Q2: Can I get a custom diameter outside the 100mm-500mm range?
Yes, we can produce custom diameters as per your drawings or specifications. Please contact our sales team with your required dimensions, and we will provide a quotation.
Q3: What does the Mill Test Report include?
The Mill Test Report (MTR) includes the chemical composition of the 304 stainless steel (e.g., Cr, Ni, C, Mn content) and mechanical properties such as tensile strength and yield strength. It is a standard document that certifies material quality.
Q4: How should I clean and maintain the filter mesh?
The mesh can be cleaned by backwashing, brushing with a soft brush, or using ultrasonic cleaning. Avoid harsh chemicals that may damage the stainless steel. Regular cleaning extends the lifespan.
Q5: Is the mesh suitable for food contact applications?
304 stainless steel is generally considered food-grade and safe for contact with food. However, for specific regulatory compliance (e.g., FDA, EU), please confirm your requirements with our team, and we can provide relevant documentation.
Q6: What is the minimum order quantity (MOQ)?
Our MOQ is typically 10 pieces for standard sizes, but we accept smaller trial orders for new customers. Contact us for details.
Q7: Can you provide samples before mass production?
Yes, we can provide samples. The sample cost and shipping are usually covered by the customer, but we may deduct the sample cost from the final order. Lead time for samples is 3-5 working days.
Q8: How do you ensure the opening size accuracy?
We use precision weaving machines and perform 100% visual inspection. The opening size is measured with calibrated tools according to ISO standards. Our quality control team ensures tolerances within ±5% of the nominal opening.
