Material

This hot-dip galvanized welded mesh adopts high-quality low carbon steel wire as the core substrate, which possesses uniform texture, good ductility and stable welding performance, ensuring solid integral mesh structure and not easy to deform or break under external force. After integral welding forming, the mesh undergoes professional high-temperature hot-dip pure zinc treatment. Unlike thin electro-galvanized layers, the hot-dip pure zinc coating tightly combines with the steel wire matrix, featuring strong adhesion and uniform coverage without missing coating or exposed steel points. The pure zinc material avoids impurity corrosion, providing lasting and stable anti-corrosion protection for the steel wire, and greatly improving the overall outdoor weather resistance of the mesh.
Product Application
With outstanding outdoor durability and anti-rust performance, hot dipped welded wire mesh is widely used in permanent outdoor protection and engineering scenarios. It is mainly applied for farm breeding fence to achieve long-term stable breeding area isolation, river slope protection mesh to prevent water and soil erosion and bank collapse, construction concrete reinforcement mesh to enhance structural firmness of concrete layers, outdoor garden permanent fence for landscape boundary protection, as well as aquaculture cage net for underwater breeding isolation, adapting to various humid, open-air and long-service-cycle engineering needs.

Production Process

The product adopts standardized high-quality hot-dip galvanizing production procedures to ensure superior anti-corrosion performance: firstly, complete steel wire straightening, fixed-length cutting and automatic welding to form neat and firm integral mesh blanks; secondly, conduct integral mesh pickling treatment to thoroughly remove welding oxide, surface rust and impurities for better zinc layer adhesion; thirdly, perform flux activation pretreatment before high-temperature zinc bath dipping to ensure uniform and compact zinc layer deposition; fourthly, adopt natural air cooling for shaping and manually wipe off excess surface zinc to obtain smooth and tidy mesh surface; finally, conduct strict quality inspection, and process qualified products into wound mesh rolls or stacked flat panels for standardized packaging and delivery.
Precaution for Use
During installation and construction, avoid violent scratching, cutting and friction on the mesh surface to prevent local damage to the hot-dip zinc layer and subsequent rusting. Do not bend the mesh excessively to avoid cracking of the protective zinc layer at bending positions. For long-term underwater and outdoor buried use, regularly check the mesh surface integrity to maintain continuous anti-corrosion performance. Avoid contact with strong acid and alkali corrosive substances to prevent accelerated zinc layer loss and extend service life.

Compare with Other Products
Compared with electro-galvanized welded mesh, hot-dip galvanized mesh has thicker zinc coating, far stronger salt spray resistance and outdoor weather resistance, suitable for long-term open-air and humid environments instead of only indoor use. Different from temporary black annealed mesh, it has excellent anti-rust capability and reusable performance. Though slightly higher in cost, its ultra-long service life and low maintenance frequency make it more cost-effective for permanent outdoor engineering and breeding projects.
