Product Overview
Galvanized welded wire mesh consists of low‑carbon steel wires that are electrically resistance‑welded at each intersection and then coated with zinc to inhibit corrosion. The welding creates a uniform grid where the wire diameter and opening size determine mechanical strength and openness. Typical zinc coatings range from 20 µm to 50 µm thickness, providing adequate protection for indoor and moderate outdoor exposure.
Technical Specifications
| Parameter | Typical Value | Customizable Range |
|---|---|---|
| Wire Diameter (mm) | 1.2 – 3.0 | 0.8 – 5.0 |
| Mesh Opening (mm × mm) | 25 × 25 | 10 × 10 to 100 × 100 |
| Roll Width (m) | 1.0 – 2.5 | 0.5 – 3.0 |
| Roll Length (m) | 10 – 50 | 5 – 100 |
| Zinc Coating (g/m²) | 150 – 350 | 80 – 600 (hot‑dip) or 30 – 120 (electro) |
| Tensile Strength (MPa) | 350 – 450 | 300 – 600 (depends on wire grade) |
Typical Applications
In concrete reinforcement the mesh provides distributed tensile capacity, reducing cracking when embedded in slabs or walls; the weld points prevent slippage under load. For agricultural fencing the open area allows visibility and airflow while the zinc coating withstands exposure to soil moisture and fertilizers. Industrial uses such as machine guarding or shelving benefit from the mesh’s rigidity and ease of cutting to size without compromising overall structural integrity.
Manufacturing Process
Wire rods are first drawn to the target diameter, achieving the required tensile strength and surface finish. Adjacent wires are then positioned in a grid and joined by electric resistance welding, which creates a metallurgical bond without additional filler material. The welded sheet passes through a hot‑dip galvanizing bath where molten zinc adheres to all surfaces, followed by cooling and tension‑levelled coiling to produce uniform rolls.
Quality Control Procedures
Each roll undergoes visual inspection for missing welds or coating defects. Dimensional checks verify wire diameter, opening size, and roll width using calibrated gauges. Coating thickness is measured by magnetic induction on multiple points per square meter to confirm compliance with the specified zinc mass. Mechanical tests include tensile strength of a welded joint and bend resistance of a sample strip, performed at a frequency of one test per 500 kg of product.

Frequently Asked Questions
Can dimensions be customized?
Yes, wire diameter, opening size, roll width and length can be tailored to project requirements; technical drawings or specifications are needed to generate an accurate quote.
What information is required before quotation?
We need the desired wire diameter, mesh opening, roll dimensions, coating type, quantity, and any special packaging or testing requirements.
What materials are available?
Base material is low‑carbon steel (grades Q195/Q235); higher tensile grades can be supplied upon request.
How is quality inspected?
Inspection includes visual checks, dimensional verification, coating thickness measurement, and mechanical tests as described in the quality control section.
What packaging methods are available?
Standard packaging uses waterproof paper and PVC film wrapped on wooden pallets; custom packaging such as cartons or steel‑banded bundles can be arranged.
How are export shipments protected?
Pallets are strapped, corner‑protected, and placed in containers with desiccants to mitigate moisture during transit.
What is the typical production lead time?
Lead time ranges from 10 to 25 working days depending on order size and customization complexity.
How are samples arranged?
Free sample sections (up to 1 m²) can be shipped upon receipt of a detailed request; freight is collect or prepaid as agreed.
