As a trusted manufacturer since 1998, Anping County Boli Hardware Wiremesh Products Factory is proud to offer the 316L Stainless Steel Weld Mesh Screen, featuring a precise 1.5mm wire diameter and 20x20mm aperture. Designed specifically for demanding marine environments, this mesh provides exceptional corrosion resistance and structural integrity. Our mesh is engineered to withstand saltwater, humidity, and UV exposure, ensuring long-lasting performance in applications such as boat building, offshore platforms, docks, and aquaculture. With an annual export value of US$5–10 million and shipping from major ports like Tianjin, Qingdao, and Shanghai, we deliver quality mesh worldwide.
Our mesh is manufactured using high-quality 316L stainless steel, which contains lower carbon content than standard 316, enhancing its weldability and resistance to intergranular corrosion. The welded construction offers uniform openings and high tensile strength, making it suitable for both functional and decorative uses in marine settings. Below are the key technical specifications:
| Parameter | Value |
| Material | 316L Stainless Steel (UNS S31603) |
| Wire Diameter | 1.5mm ± 0.05mm |
| Aperture (Mesh Opening) | 20mm x 20mm (Square) |
| Open Area | Approximately 69% |
| Standard Sheet Size | 1m x 2m (custom sizes available) |
| Surface Finish | Mill finish; optional pickling, passivation, or PVC coating |
| Tensile Strength | ≥ 500 MPa (typical) |
Key Features & Benefits:
- Superior Corrosion Resistance: 316L stainless steel contains molybdenum, which provides excellent resistance to chlorides (e.g., seawater) and acidic environments, making it ideal for marine applications.
- High Strength & Durability: The welded construction with 1.5mm wire ensures robust mechanical strength, capable of withstanding heavy loads, impacts, and constant vibration on boats or offshore structures.
- Precise Aperture: The 20x20mm opening allows for efficient water flow, filtration, or ventilation while preventing larger debris or marine organisms from passing through. It is also suitable for safety barriers and grilles.
- Customizable Dimensions: We offer mesh in custom widths, lengths, and shapes (cut-to-size, rolls, or panels) to fit your specific project requirements. Edge treatments such as hemming or welding are available.
- Easy Installation: The mesh can be cut, bent, welded, or fastened with standard tools, reducing installation time and labor costs.
- Low Maintenance: The non-porous surface resists fouling, rust, and staining, requiring only occasional rinsing with fresh water to maintain appearance.
Application Examples:
- Boat hull screening, engine room ventilation grilles, and deck drainage covers
- Offshore platform walkways, guardrails, and debris screens
- Aquaculture cages, fish farm pens, and water intake filters
- Marine exhaust system components and heat exchanger protection
- Security fencing for coastal facilities and piers

Frequently Asked Questions (FAQ)
Q1: What is the difference between 316 and 316L stainless steel weld mesh?
A: 316L has a lower carbon content (max 0.03%) compared to 316 (max 0.08%). This reduces the risk of carbide precipitation during welding, making 316L more suitable for welded mesh and marine environments where corrosion resistance is critical.
Q2: Can this mesh be used for saltwater aquariums or fish farms?
A: Yes. The 316L grade is highly resistant to chloride-induced pitting and crevice corrosion, making it an excellent choice for aquaculture cages, water intake screens, and aquarium partitions.
Q3: What standard sheet sizes do you offer, and can I get custom dimensions?
A: Our standard sheet size is 1m x 2m, but we can produce custom widths, lengths, and even rolls. Please provide your required dimensions, and we will confirm feasibility and pricing.
Q4: Is the mesh supplied with a flat or rolled edge? Can I get hemmed edges?
A: The mesh is typically supplied with cut edges. Hemming, welding, or plastic edge finishing are available upon request for added safety and ease of installation.
Q5: How do you pack the mesh for export to prevent damage?
A: We pack the mesh in wooden crates or pallets with protective wrapping. For small orders, we use cardboard boxes. All packaging is suitable for sea freight or air freight.
Q6: What is the typical lead time for an order of 100 sheets?
A: For standard sizes, the lead time is 10–15 working days after confirmation. For custom sizes, it may be 15–25 working days. We will provide a specific schedule upon order.
Q7: Do you provide free samples?
A: Yes, we offer free samples (up to A4 size) for quality evaluation. The buyer only needs to cover the shipping cost. Contact us for sample availability.
Q8: Can this mesh be welded to stainless steel frames?
A: Absolutely. The 316L composition is weldable using standard TIG or MIG techniques. We recommend using 316L filler rods to maintain corrosion resistance at the weld joints.
