As a professional manufacturer based in Anping, Hebei — the renowned wire mesh capital of China — Anping Xinye Metal Wire Mesh Products Co., Ltd proudly offers this 304 Stainless Steel Expanded Metal Mesh with a precise 1.5mm thickness and 10mm x 20mm diamond openings. Engineered for outstanding corrosion resistance and structural integrity, this expanded metal mesh is the ideal solution for demanding industrial, architectural, and filtration applications. Our factory, spanning 5,000-10,000 square meters, combines advanced manufacturing techniques with rigorous quality control to ensure every sheet meets your exact performance expectations.
Why Choose 304 Stainless Steel Expanded Metal Mesh?
- Superior corrosion resistance — 304 grade stainless steel withstands moisture, chemicals, and harsh environments, making it suitable for outdoor and marine applications.
- Structural strength without excess weight — the expansion process creates a rigid, load-bearing sheet while saving material and cost.
- Continuous diamond openings allow excellent airflow, visibility, and drainage, ideal for safety barriers, machine guards, and ventilation panels.
- Low maintenance and long service life — resistant to rust and oxidation, reducing replacement frequency and lifecycle costs.
- Versatile fabrication — can be cut, bent, welded, or formed to meet custom specifications, offering design flexibility.

Detailed Features and Benefits
This 304 stainless steel expanded metal mesh is produced by simultaneously slitting and stretching a solid metal sheet, creating a seamless diamond-patterned mesh. Unlike woven wire mesh, expanded metal mesh has no openings at intersections, which greatly increases its mechanical strength and prevents unraveling. The 10mm x 20mm diamond opening offers an optimal balance of openness and security — sufficiently large for ventilation and visibility, yet tight enough to block debris and provide effective guarding.
Key technical advantages include:
- The 1.5mm thickness provides enhanced rigidity and impact resistance, suitable for heavy-duty industrial environments.
- 304 stainless steel contains 18% chromium and 8% nickel, giving it excellent resistance to intergranular corrosion and oxidation.
- The non-slip surface texture (when specified as flattened) improves safety for walkways and platforms.
- Uniform openings ensure consistent performance in filtration, screening, and separation processes.
- Lightweight compared to solid sheet metal, reducing structural load and simplifying installation.
Common Application Areas
- Security and protection: window guards, partition walls, machine guarding, and safety enclosures.
- Architectural design: decorative facades, sun shading panels, railing infills, and ceiling cladding.
- Industrial use: filter supports, fan covers, ventilation grilles, and conveyor guards.
- Agricultural and marine: animal enclosures, greenhouse shelving, dock fenders, and anti-corrosion platforms.
- Furniture and display: shelving, display racks, and storage baskets.

Frequently Asked Questions
| Q1 | Can you provide samples for testing? | Yes, we offer small samples free of charge, with only shipping cost covered by the customer. Samples are usually available within 3-5 working days. |
| Q2 | Is this mesh suitable for outdoor marine environments? | Yes, 304 stainless steel has good corrosion resistance against saltwater and humidity. For extremely aggressive marine or chemical environments, we can also supply 316L grade upon request. |
| Q3 | What is the minimum order quantity for this product? | Our standard MOQ is 100 square meters, but we are flexible for pilot orders and can discuss based on your project requirements. |
| Q4 | Can you cut the mesh into custom shapes and sizes? | Absolutely. We can cut sheets to your exact dimensions, supply strips, or process into panels with bent edges or flattened surfaces. |
| Q5 | How is the product packed to prevent damage during shipping? | Sheets are packed in wooden pallets or export crates with corner protection and waterproof wrapping. Small pieces are secured in bundles with steel strapping. |
| Q6 | Do you have this product in stock? | Standard sizes are often in stock. For custom dimensions, production usually takes 7-15 days depending on order quantity. |
| Q7 | What is the difference between standard and flattened expanded metal? | Standard expanded metal has a rough, anti-slip surface with raised edges. Flattened mesh is rolled smooth for a flat profile, often used for architectural and decorative purposes. |
| Q8 | How can I get a quick quote? | Simply provide your required dimensions, thickness, opening size, and quantity. Our sales team will respond within 24 hours with a detailed quotation. |
