Each step is critical, adhering to stringent international standards such as ISO 9001 for quality management and ASTM A740 for metallic-coated steel wire.

Step-by-Step Manufacturing Process:

1. Raw Material Selection: High-tensile steel wire, typically low-carbon steel (e.g., Q195 or Q235), is sourced, ensuring uniform diameter and metallurgical composition. Wire diameters can range from 0.5mm to 6.0mm depending on the application.
2. Wire Straightening and Cutting: The raw wire coils are straightened and cut to precise lengths required for the welding process, minimizing material waste and ensuring dimensional accuracy.
3. Welding (Resistance Welding): Individual wires are arranged perpendicularly and welded at each intersection point using advanced resistance welding machines. This creates a strong, monolithic mesh structure with uniform apertures. Common mesh sizes include 1 2 inch pvc coated wire mesh, 1 inch, 2x2 inch, etc. The integrity of these welds is paramount, undergoing rigorous pull-out strength tests.
4. Surface Preparation (Pre-treatment): Before PVC coating, the welded mesh undergoes extensive cleaning. This typically involves degreasing, pickling (acid treatment to remove rust and scale), rinsing, and phosphating. This crucial step ensures optimal adhesion of the PVC coating to the steel substrate, preventing delamination and enhancing corrosion resistance.
5. Primer Application (Optional but Recommended): For superior adhesion and enhanced corrosion protection, a specialized primer layer (often epoxy-based) can be applied. This serves as an intermediate bonding agent between the steel and the PVC, particularly important for demanding environments.
6. PVC Coating (Fluidized Bed or Electrostatic Spray):
   • Fluidized Bed Dip Coating: The pre-heated mesh is immersed in a bed of finely powdered PVC. The heat causes the PVC powder to melt and fuse onto the mesh, forming a thick, uniform, and durable coating. This method is excellent for achieving consistent coating thickness.
   • Electrostatic Spray Coating: PVC powder is electrostatically charged and sprayed onto the grounded mesh. The electrostatic attraction ensures even coverage, after which the mesh is heated (cured) to melt and cross-link the PVC, creating a robust finish. This method allows for fine control over coating thickness.
   The coating thickness typically ranges from 0.4mm to 1.0mm, directly influencing durability and corrosion resistance. Popular colors include green and black vinyl coated welded wire fence options.
7. Curing: The coated mesh is then passed through a curing oven where the PVC layer is polymerized and solidified, ensuring maximum adhesion and hardness.
8. Cooling and Inspection: After curing, the mesh is gradually cooled. A thorough inspection follows, checking for coating uniformity, adhesion, color consistency, and the absence of defects. Quality control teams ensure compliance with specifications like ASTM F668 (PVC Coated Chain-Link Fence Fabric) for relevant products, and test for impact resistance and salt spray performance.
9. Packaging: The finished pvc coated welded wire mesh is then rolled or cut into panels and securely packaged for shipment, protecting the coating during transit. Common forms include green pvc coated steel welded wire rolled fencing.

This rigorous manufacturing process ensures that the final product offers an extended service life, often exceeding 15-20 years in typical environments, and provides superior energy saving through reduced maintenance needs and exceptional corrosion resistance, making it ideal for target industries like petrochemical, metallurgy, and water supply & drainage.
