At Anping Xinye Metal Wire Mesh Products Co., Ltd, we manufacture industrial wire mesh solutions engineered for demanding environments. Our 316L marine grade expanded metal mesh combines the structural efficiency of diamond-shaped mesh with the exceptional corrosion resistance of 316L stainless steel. Every sheet is produced with a protective anti-corrosion coating and includes a mill test report, providing full material traceability and long-term reliability. This product is built to withstand saltwater, harsh chemicals, and high-moisture conditions where ordinary carbon steel mesh would quickly fail.
Expanded metal mesh starts from solid 316L stainless steel sheet, which is simultaneously slit and stretched through a high-precision expansion process. The result is a continuous, joint-free mesh with diamond-shaped openings. Because there are no welded intersections and no separate wires, the structure gains additional strength and rigidity. This unique manufacturing method also creates a naturally slip-resistant surface, which is a distinct advantage for flooring, walkways, and safety applications in marine and industrial settings.
Key Features
- Uses premium 316L stainless steel with low carbon content to minimize carbide precipitation during welding while maintaining excellent mechanical properties.
- Diamond-shaped openings are expanded directly from a single sheet, creating a joint-free structure with no loose wires or welds.
- Anti-corrosion coating provides an additional protective layer that helps defend against seawater, humidity, and chemical exposure.
- Mill test report is supplied with each order, documenting material composition and mechanical properties for full traceability.
- Designed for marine-grade service: excellent performance in salt spray, brackish water, and high-chloride environments.
- Optimal strength-to-weight ratio reduces structural weight while providing sturdy protection and screening capabilities.
- Available in a variety of sheet dimensions and opening sizes to suit flexible project requirements.

Detailed Advantages
The 316L grade stainless steel used in this mesh has a lower carbon content than standard 316, which improves its resistance to sensitization and intergranular corrosion after welding. It also contains higher molybdenum and nickel levels, giving the material enhanced pitting and crevice corrosion resistance in chloride-laden environments such as seawater and coastal atmospheres. For projects that demand long-term integrity, this grade is the appropriate choice, offering an excellent balance of mechanical strength and corrosion performance.
The anti-corrosion coating is an added defense layer that helps protect the mesh against surface contamination, oxidation, and aggressive media during storage, transport, and installation. It supports the inherent corrosion resistance of 316L stainless steel, ensuring the mesh maintains its appearance and structural performance for years. The coating also reduces the need for frequent cleaning and maintenance, lowering the total cost of ownership for end users.
We offer a high level of flexibility for your projects. The expanded metal mesh is available in multiple sheet widths, lengths, and diamond opening sizes. You can order it in flat form or as expanded and flattened mesh depending on your requirement. Custom cutting, packaging, and edge preparation are also available upon request. Our team will work with you to determine the most efficient configuration and ensure that every shipment meets your exact specifications.
Another key advantage is material traceability and quality assurance. Each shipment includes a mill test report that lists the material grade, heat number, chemical composition, and mechanical properties of the stainless steel used. This documentation gives engineers, contractors, and procurement teams confidence when specifying our product for critical installations. Combined with a one-year warranty against manufacturing defects, you receive both technical evidence and commercial protection.
Key Benefits for Customers
- Long service life in saltwater and humid environments leads to lower maintenance costs and less frequent replacement.
- Joint-free diamond construction eliminates weld corrosion and stress concentration points.
- Slip-resistant surface increases safety for walkways, decks, and outdoor platforms.

Frequently Asked Questions
Q1: What is the difference between 316 and 316L stainless steel in this expanded metal mesh?
316L has a lower carbon content than standard 316, which reduces the risk of sensitization and intergranular corrosion when the material is welded or exposed to high temperatures. This makes 316L a preferred choice for marine and chemical environments, especially when fabrication involves welding.
Q2: Can the mill test report be sent before shipment?
Yes, the mill test report is included with the order and can be provided for your review prior to shipment upon request. Simply coordinate with your sales representative, and we will arrange the documentation for your inspection.
Q3: Is the anti-corrosion coating suitable for underwater applications?
The coating enhances resistance against atmospheric and splash-zone corrosion. For fully submerged service, please specify the expected water conditions, temperature, and duration so that we can recommend the best coating type and thickness for the application.
Q4: Can we order custom sizes or irregular opening patterns?
We can customize sheet width, length, opening size, strand width, and thickness. Diamond-shaped openings are standard for this product, but other configurations are available upon request from our factory.
Q5: How should the mesh be cut and installed?
The mesh can be cut with standard shears, plasma cutters, or grinding tools. Because it has a joint-free construction, it will not unravel or lose structural integrity around the cut edges, simplifying on-site handling and installation.
Q6: What packaging is provided for export orders?
Expanded metal mesh is usually packed in wooden crates, plywood pallets, or steel-framed bundles with protective wrapping to avoid damage during transit. We can customize packaging according to your shipping method and handling requirements.
Q7: Are samples available before placing a bulk order?
Sample orders are available. We can produce small sample pieces with the same 316L material and anti-corrosion coating to verify quality, dimensions, and surface finish prior to mass production.
