Expanded Galvanized Steel Mesh
This product consists of low‑carbon steel sheets that have been slit and stretched to form a uniform diamond‑pattern opening, then coated with a protective zinc layer through hot‑dip galvanizing. The resulting mesh offers a combination of open area for flow or visibility and structural rigidity suitable for load‑bearing applications.
Product Overview
Expanded galvanized steel mesh is supplied as flat sheets or rolls, with dimensions tailored to the specific requirements of civil, industrial, or agricultural projects. The manufacturing process preserves the steel’s tensile strength while the zinc coating provides long‑term resistance to atmospheric corrosion.
Key Specifications
| Parameter | Typical Value | Notes |
|---|---|---|
| Base Steel Grade | Q235 or equivalent | Cold‑rolled, low carbon |
| Galvanizing Method | Hot‑dip zinc coating | Average coating weight 275 g/m² (both sides) |
| Mesh Opening (Short Way) | 12 mm – 100 mm (customizable) | Depends on required open area |
| Strand Diameter | 1.5 mm – 4.0 mm (customizable) | Affects tensile strength |
| Sheet Width | Up to 1250 mm | Length up to 3000 mm (rolls or flat sheets) |
| Tensile Strength (base steel) | ≥ 370 MPa | Measured per ISO 6892‑1 |
Manufacturing Process
The base coil is first slit to the desired width, then passed through an expanding press where simultaneous stretching and slitting creates the diamond pattern. After expansion, the mesh is cleaned, fluxed, and immersed in a molten zinc bath at approximately 450 °C. The coating thickness is controlled by withdrawal speed and bath composition, followed by air cooling and optional passivation.
Typical Applications
- Concrete reinforcement in precast panels – provides crack control and load distribution.
- Fencing and security barriers – offers corrosion resistance and high visibility.
- Ventilation grilles and HVAC diffusers – allows airflow while protecting equipment.
- Shelving and racking decks – supplies a stiff, non‑slip surface for pallet storage.
- Animal enclosures – combines strength with smooth edges to reduce injury risk.
Customization Options
Customers can specify opening size, strand diameter, sheet dimensions, and coating weight to match structural or functional needs. Additional options include pre‑cut lengths, edge treatment (flattened or rounded), and secondary processes such as powder coating or PVC over‑coating for specialized environments.
Quality Assurance
Each production lot undergoes dimensional verification using laser scanning or calibrated gauges, tensile testing of base steel specimens, and coating thickness measurement via magnetic‑induction probes. Visual inspection ensures uniform zinc coverage and absence of defects such as bare spots or excessive dross.
FAQ
Can dimensions be customized?
Yes. Opening size, strand diameter, sheet width and length are adjusted according to project drawings.
What information is required for a quotation?
Required data includes mesh opening, strand diameter, sheet dimensions, coating weight, quantity, and any special tolerances.
How is the galvanized coating inspected?
Coating thickness is measured with a magnetic‑induction gauge per ISO 1461; visual inspection checks for uniformity and adhesion.
