China Custom Galvanized Wire Mesh Company
Galvanized wire mesh is produced by weaving low-carbon steel wire and applying a zinc coating via hot-dip or electro-galvanizing to protect against corrosion. The mesh opening and wire diameter are selected based on load requirements and environmental exposure.
Material and Specifications
The base wire is typically low-carbon steel (C ≤ 0.12%) with a tensile strength ranging from 350 to 550 MPa depending on cold work. Zinc coating is applied by hot-dip galvanizing, delivering coating weights from 10 g/m² for light indoor use to 270 g/m² for severe outdoor environments. Mesh opening sizes vary from 6 mm to 100 mm, and wire diameters range from 0.8 mm to 4.0 mm.
| Parameter | Typical Range | Notes |
|---|---|---|
| Wire Diameter | 0.8 mm – 4.0 mm | Customizable according to project requirements |
| Opening Size | 6 mm – 100 mm | Customizable according to project requirements |
| Tensile Strength | 350 – 550 MPa | Depends on wire cold work |
| Zinc Coating Weight | 10 – 270 g/m² | Hot-dip galvanizing |
| Roll Width | 0.5 m – 2.5 m | Customizable |
| Roll Length | 10 m – 50 m | Customizable |
Manufacturing Process
Wire is drawn to the target diameter through a series of dies, reducing cross‑section while increasing tensile strength. The drawn wire is woven on automated looms to produce the specified opening pattern, with tension monitored to maintain uniform mesh geometry. After weaving, the mesh passes through a cleaning line to remove oils, then is immersed in a molten zinc bath at approximately 450 °C for hot‑dip galvanizing, followed by air cooling and passivation.
Customization Options
Customization begins with selecting the wire diameter that matches the load and deflection requirements of the application.
- Wire diameter from 0.8 mm to 4.0 mm, selected based on load and deflection limits.
- Opening shapes: square, rectangular, or hexagonal, with aperture sizes from 6 mm to 100 mm.
- Roll width up to 2.5 m and length up to 50 m, or cut‑to‑length panels.
- Edge treatments: selvage, folded, or welded edges for safety and ease of handling.
- Zinc coating weight adjustable from 10 g/m² to 270 g/m², or optional PVC over‑coat for additional chemical resistance.
Applications
Used as reinforcement in concrete slabs and walls, the mesh distributes tensile stresses and controls cracking while the zinc coating protects against chloride ingress in humid environments.
Employed as livestock fencing and crop protection, the opening size prevents animal passage while allowing ventilation and light, and the corrosion resistance extends service life in outdoor conditions.
Utilized as screening media in quarries and recycling plants, the rigid mesh withstands impact from aggregate flow, and the opening size is calibrated to sort particles by size.
Quality Control
Before shipment, each roll undergoes dimensional verification using laser gauges to confirm wire diameter and opening tolerance within ±0.05 mm. Coating thickness is measured with magnetic induction probes to ensure compliance with the specified zinc weight. Tensile samples are pulled to verify strength meets the declared range.
