Welcome to Anping County Boli Hardware Wiremesh Products Factory – your trusted manufacturer of premium wire mesh since 1998. Our Duplex 2507 Stainless Steel Wire Mesh (0.25mm wire, 50 mesh) is engineered for high‑corrosion environments where strength and durability matter. With over two decades of experience and annual exports exceeding US$5 million, we deliver technical support and a solid warranty to ensure your project success.
This wire mesh is crafted from Duplex 2507 (UNS S32750), a super duplex stainless steel offering twice the yield strength of standard 316L and excellent resistance to pitting, crevice corrosion, and stress corrosion cracking. The 0.25mm wire diameter combined with 50 mesh provides a balanced open area (~30%) for efficient filtration while maintaining mechanical integrity. Ideal for demanding applications in oil & gas, chemical processing, marine engineering, and water treatment.
Key Features & Technical Specifications
- Superior Corrosion Resistance: Duplex 2507 withstands chlorides, acids, and alkaline solutions – perfect for offshore platforms, desalination plants, and chemical reactors.
- High Strength: Yield strength > 550 MPa, allowing thinner wires without sacrificing load capacity, saving weight and cost.
- Precise Mesh Opening: 50 mesh with 0.25mm wire gives a consistent aperture of ~0.5 mm, ensuring reliable particle retention.
- Excellent Weldability: Can be cut, welded, and formed into custom shapes (filter discs, cylinders, baskets) with minimal loss of corrosion resistance.
- Low Maintenance: Resists biofouling and scaling, reducing cleaning frequency in continuous processes.
- Technical Support: Our engineers help you select the right mesh, weave, and edge treatment for your specific application.
- Warranty Coverage: Standard 12‑month warranty against material defects and workmanship.

Frequently Asked Questions
-
What is the difference between Duplex 2507 and standard 316L stainless steel mesh?
Duplex 2507 has roughly twice the yield strength and superior resistance to chloride stress corrosion cracking. It is more suitable for harsh environments like offshore, chemical, and desalination plants. -
Can this mesh be used for liquid filtration?
Yes, the 50 mesh (0.5 mm opening) is ideal for coarse to medium filtration. For finer filtration, we offer higher mesh counts in the same material. -
Do you provide custom sizes?
Absolutely. We can cut to specific widths and lengths, or fabricate into finished products like filter discs, baskets, or cylinders. -
Is the mesh easy to weld or form?
Duplex 2507 can be welded with appropriate filler metals. We recommend using a qualified welder. Our technical support can provide guidelines. -
What kind of warranty do you offer?
We provide a standard 12‑month warranty covering material defects and workmanship. Extended warranty options are available for large orders. -
How is the mesh packaged for export?
It is rolled on cardboard cores, wrapped in waterproof paper, and then packed in plywood crates or steel pallets to prevent damage during shipping. -
Can I get a sample before placing a bulk order?
Yes, sample rolls (e.g., 1 m²) are available for a nominal fee, which is refundable upon bulk order. Contact our sales team for details. -
What is the typical lead time?
For standard sizes, 7–15 working days. Custom sizes or large quantities may require 20–30 days, depending on the order volume.
