As a leading manufacturer since 1998, Anping County Boli Hardware Wiremesh Products Factory specializes in producing high-quality Duplex Stainless Steel Wire Mesh designed for the most demanding chemical processing environments. Our wire mesh combines exceptional strength with superior acid resistance, ensuring long-lasting performance in corrosive applications. With annual export values exceeding US$5 million and a global distribution network covering North America, Europe, Asia, and beyond, we deliver reliable solutions trusted by industries worldwide.
This product is engineered to withstand aggressive chemicals, high temperatures, and mechanical stress, making it the ideal choice for filtration, separation, and support structures in chemical plants, refineries, and pharmaceutical facilities. Every roll is manufactured with precision using advanced weaving technology and strict quality control, ensuring consistent mesh geometry and uniform mechanical properties.
Below we highlight the key features, technical specifications, and benefits that set our duplex stainless steel wire mesh apart from standard alternatives.
Key Features
- High Strength & Durability: Duplex stainless steel offers twice the yield strength of conventional 304 or 316 grades, allowing for thinner wires and lighter meshes without compromising performance.
- Exceptional Acid Resistance: Excellent resistance to sulfuric acid, hydrochloric acid, nitric acid, and many organic acids, even at elevated temperatures.
- Corrosion & Stress Cracking Resistance: The dual-phase microstructure (austenite + ferrite) provides superior resistance to chloride stress corrosion cracking and pitting.
- Customizable Specifications: Available in a wide range of mesh sizes from 1 to 400 mesh, wire diameters from 0.025 mm to 6.0 mm, and roll widths up to 2.0 meters.
- Versatile Weave Patterns: Offered in plain weave, twill weave, and Dutch weave to suit different filtration ratings and strength requirements.
- Thermal Stability: Maintains mechanical properties in temperatures from -50°C to 300°C, suitable for thermal cycling processes.
- Easy Fabrication: Can be cut, welded, and formed into custom shapes such as discs, cylinders, or filter cartridges.

Benefits for Your Chemical Processing Operations
- Reduced Downtime: The superior corrosion resistance means fewer replacements and maintenance intervals, keeping your production lines running.
- Improved Filtration Efficiency: Precise mesh openings ensure consistent particle separation, critical for product quality in pharmaceutical and fine chemical applications.
- Cost Savings: Although duplex stainless steel has a higher initial cost than 304, its longer service life and lower maintenance make it more economical over the equipment lifecycle.
- Safety: High strength reduces the risk of mesh rupture under pressure or mechanical stress, preventing contamination and equipment damage.
- Global Compatibility: Our mesh meets international standards and can be supplied with certificates of material and analysis upon request.
Our duplex stainless steel wire mesh is extensively used in chemical reactors, distillation columns, catalyst recovery systems, acid mist filters, and liquid-solid separation units. The combination of high strength and acid resistance allows it to perform reliably in environments where standard mesh would fail within weeks.
Over the past two decades, Anping County Boli Hardware Wiremesh Products Factory has exported to over 20 countries across North America, South America, Europe, Africa, Oceania, and Asia. Our annual export value of US$5 million to US$10 million reflects the trust our customers place in our products. We ship from major ports including Tianjin, Qingdao, Shanghai, and Foshan, ensuring timely delivery worldwide.
We are committed to providing customizable solutions – whether you need a specific mesh size, special edge treatment, or cut-to-size panels, our experienced team can accommodate your requirements.

Frequently Asked Questions (FAQ)
Q1: What is the difference between duplex stainless steel wire mesh and 316L mesh?
A: Duplex stainless steel (e.g., 2205) has a two-phase microstructure, providing roughly twice the yield strength of 316L and superior resistance to chloride stress corrosion cracking. It is particularly suitable for aggressive acidic environments, while 316L may be adequate for milder conditions.
Q2: Can this mesh be used for high-temperature filtration?
A: Yes, it operates effectively from -50°C to 300°C. For temperatures above 300°C, special heat treatment may be required; please consult our engineers for specific applications.
Q3: What are the available weave types?
A: We offer plain weave (standard square mesh), twill weave (for finer mesh and higher strength), and Dutch weave (for precise filtration with high flow rates). Custom weaves are available on request.
Q4: Do you provide cut-to-size pieces or only rolls?
A: We supply both rolls and cut-to-size sheets, discs, or custom shapes. Please specify your dimensions when ordering.
Q5: Is the mesh certified for chemical resistance?
A: While we do not hold specific chemical resistance certifications, we provide material test certificates (MTC) and can share corrosion resistance data from third-party tests. Our grades are widely accepted in the chemical industry.
Q6: What is the minimum order quantity (MOQ)?
A: Our MOQ is typically 100 square meters for standard sizes, but smaller quantities are available for sample orders or custom projects. Please contact us for details.
Q7: How long does delivery take?
A: For standard products, production takes 10–15 working days after order confirmation. Shipping time depends on the destination port (typically 15–30 days by sea).
Q8: Can you provide samples before bulk order?
A: Yes, we offer free samples (up to 0.1 square meter) for evaluation. The buyer pays the shipping cost, which is refundable for first orders over US$500.
