This facility produces welded and woven wire mesh panels made from austenitic stainless steel grades for industrial perimeter protection, process area segregation, and environmental barriers. The product line emphasizes dimensional consistency, corrosion resistance, and load‑bearing capacity suited to continuous operation in harsh environments.
Material Composition and Grades
Panels are fabricated from either AISI 304 (18% Cr, 8% Ni) or AISI 316 (16% Cr, 10% Ni, 2% Mo) stainless steel wire. The molybdenum addition in 316 improves resistance to chloride‑induced pitting, making it suitable for marine splash zones and chemical processing areas where sodium hypochlorite or sulfuric acid vapors are present. Wire diameters range from 1.2 mm to 4.0 mm, with tensile strengths between 550 MPa and 750 MPa depending on grade and cold‑work level.
Manufacturing Process
Wire is first drawn to the specified diameter, then straightened and cut to length. For woven mesh, wires are interlaced on a loom at precise pitch and subsequently spot‑welded at each crossover to prevent slippage. For welded mesh, longitudinal and transverse wires are positioned in a grid and resistance‑welded at every intersection. Post‑weld, panels undergo a passivation bath (nitric acid 20‑25 % at 60 °C) to restore the chromium oxide layer, followed by a visual inspection for weld uniformity.
Standard Product Configurations
| Mesh Type | Wire Diameter (mm) | Opening Size (mm) | Panel Height (m) | Standard Length (m) | Typical Use |
|---|---|---|---|---|---|
| Woven | 1.6 | 25×25 | 2.0 | 6.0 | Food‑grade processing lines |
| Welded | 2.5 | 50×50 | 2.5 | 6.0 | Chemical plant perimeter |
| Welded | 3.2 | 75×75 | 3.0 | 6.0 | Marine dock fencing |
| Woven | 1.2 | 12×12 | 1.5 | 4.0 | Laboratory containment |
Customization Options
- Wire grade selection: 304L, 316L, 321 for high‑temperature service.
- Diameter range: 0.8 mm to 5.0 mm in 0.1 mm increments.
- Opening patterns: square, rectangular, hexagonal, or custom slot profiles.
- Panel dimensions: height up to 4 m, length up to 12 m with seamless splicing options.
- Edge finishes: flush cut, rolled edge, or PVC‑coated safety lip.
- Surface treatments: electropolishing for sterile environments, or powder‑coated RAL colors for UV protection.
Industrial Applications
In petrochemical refineries, the mesh serves as a spark‑arresting barrier around flare stacks, where the 316L grade resists sulfidation at temperatures up to 600 °C. For pharmaceutical cleanrooms, 304L woven panels with 12 mm openings provide particulate containment while allowing airflow rates above 0.5 m/s, meeting ISO 14644‑1 Class 7 requirements. Marine offshore platforms utilize welded mesh with 75 mm openings as walkway grating; the high molybdenum content reduces pitting corrosion in saline splash zones, extending service life beyond five years without coating replacement.
Quality Control and Testing
Each batch undergoes dimensional verification using laser scanning (±0.2 mm tolerance on wire diameter and opening size). Tensile strength is measured on samples per ASTM A370, with acceptance criteria matching the specified grade’s minimum yield. Corrosion resistance is assessed via salt‑spray testing (ASTM B117) for 500 hours; visual inspection confirms no red rust formation. Weld integrity is checked by ultrasonic scanning to detect lack‑of‑fusion or porosity exceeding 2 mm². All test reports are traceable to the raw material lot number and retained for a minimum of three years.
Packaging and Logistics
Panels are bundled in groups of five, separated by polyethylene sheets to prevent surface abrasion. Bundles are placed on steel‑frame pallets (1000 mm×1200 mm) and secured with polyester strapping. For export, pallets are fitted with corner protectors and wrapped in stretch film, then loaded into 20‑foot or 40‑foot containers with a maximum gross weight of 24 tons per container. Each shipment includes a packing list, material certification, and test certificate copy attached to the exterior of the container door.
