Welcome to Anping County Boli Hardware Wiremesh Products Factory – your trusted manufacturer of high-performance wire mesh since 1998. Our Duplex Stainless Steel Wire Mesh is specifically engineered for the demanding environment of seawater desalination filtration, offering exceptional corrosion resistance and long service life. With an annual export value of US$5–10 million, we serve global markets including North America, Europe, Southeast Asia, and the Middle East, ensuring reliable supply and consistent quality.
This premium wire mesh is woven from duplex stainless steel (2205/2507), which combines the best properties of austenitic and ferritic stainless steels. It provides superior resistance to chloride stress corrosion cracking, making it ideal for reverse osmosis (RO) pre-filtration, seawater intake screens, and brine treatment systems. The mesh is available in a wide range of mesh sizes, wire diameters, and roll dimensions to meet your exact filtration requirements.
Key Features & Benefits
- Exceptional Corrosion Resistance: Duplex stainless steel withstands aggressive seawater environments, reducing the risk of pitting, crevice corrosion, and stress cracking.
- High Mechanical Strength: Twice the yield strength of 304/316 stainless steel, allowing for thinner wires and higher open area without sacrificing durability.
- Precise Filtration Performance: Available from 10 mesh (coarse) to 400 mesh (fine), enabling effective removal of suspended solids, sand, silt, and marine organisms.
- Long Service Life: Resists biofouling and chemical attack, minimizing replacement frequency and maintenance costs.
- Customizable Dimensions: Widths from 1m to 2m, lengths up to 30m per roll, and custom mesh sizes upon request.
- Easy to Clean & Maintain: Smooth surface prevents debris accumulation; suitable for backwashing and chemical cleaning.

Frequently Asked Questions (FAQ)
-
Q: What is the main advantage of duplex stainless steel over 316L for seawater filtration?
A: Duplex stainless steel offers nearly double the yield strength and superior resistance to chloride stress corrosion cracking, making it much more durable in high-chloride environments like seawater. -
Q: Can this wire mesh be used in reverse osmosis (RO) pre-filtration?
A: Yes, it is commonly used as a pre-filter screen to remove large particles, sand, and marine organisms before RO membranes, protecting them from fouling. -
Q: Are custom mesh sizes and roll dimensions available?
A: Absolutely. We can produce mesh with aperture sizes from 0.5mm to 5mm, widths up to 2m, and lengths as required. Please provide your specifications. -
Q: How does this mesh perform in high-temperature brine?
A: Duplex 2205 and 2507 maintain excellent mechanical properties and corrosion resistance up to 300°C, suitable for thermal desalination processes. -
Q: What is the typical lead time for orders?
A: For standard rolls, lead time is 10–15 working days. Custom orders may take 20–25 days depending on complexity. We can expedite for urgent projects. -
Q: Do you provide samples for testing?
A: Yes, we offer free samples (customer pays shipping) for evaluation. Please contact us with your requirements. -
Q: Is the mesh suitable for offshore platform intake screens?
A: Yes, its high strength and corrosion resistance make it ideal for deep-sea intake screens, wave screens, and fish exclusion systems. -
Q: What packaging is used for export?
A: Each roll is wrapped in waterproof paper, bubble film, and secured with steel straps. Then packed in wooden crates or pallets for safe ocean freight.
