Product Overview
The mesh is produced by welding intersecting steel wires at each junction, forming a rigid grid. After welding, the entire panel undergoes a black powder coating process where electrostatically applied pigment is cured to create a durable, uniform film.
Material and Construction
Base wire is typically low‑carbon steel (ASTM A1008) with diameters ranging from 1.0 mm to 4.0 mm. Welding is performed using resistance spot welding, ensuring consistent joint strength without weakening the wire.
The powder coating is applied in a thickness of 60‑100 µm, providing barrier protection against moisture and UV exposure while maintaining a matte black finish.
Typical Specifications
| Parameter | Typical Range | Notes |
|---|---|---|
| Wire Diameter | 1.0 mm – 4.0 mm | Selected per load requirement |
| Mesh Opening (Clear) | 10 mm – 100 mm | Square or rectangular patterns |
| Roll Width | 0.5 m – 2.0 m | Custom widths available |
| Coating Thickness | 60 µm – 100 µm | Measured per ASTM D4138 |
| Tensile Strength of Wire | ≥ 350 MPa | Typical for low‑carbon steel |
Applications
The coating adds corrosion resistance, making the mesh suitable for environments where untreated steel would degrade quickly.
- Security fencing for industrial sites – the rigid weld prevents cutting and the black finish reduces visual impact.
- Machine guarding – openings sized to stop debris while allowing visibility and airflow.
- Concrete reinforcement in precast panels – the weld grid distributes loads and the coating protects against alkali attack.
- Architectural cladding and infill – provides a uniform appearance with long‑term color stability.
- Animal enclosures – smooth coating reduces abrasion and is easy to clean.
Quality Control
Each batch undergoes visual inspection for coating uniformity, followed by adhesion testing (cross‑hatch per ASTM D3359) and weld shear strength verification.
Dimensional checks are performed on wire diameter, opening size, and roll width using calibrated calipers and laser scanners to ensure tolerances stay within ±0.1 mm for wire and ±2 mm for opening.
Customization Options
Customers can specify wire diameter, opening pattern, roll length, and coating color (black is standard; other RAL colors available upon request).
Additional treatments such as anti‑static additives or UV stabilizers can be incorporated into the powder coat for specialized environments.
Packaging and Shipping
Mesh is rolled onto cardboard cores, wrapped in polyethylene film, and placed on pallets with corner protectors. Rolls are secured with polyester straps to prevent shifting.
For export, pallets are fumigated and loaded into containers with moisture‑absorbing desiccants. Tracking numbers and packing lists are provided with each shipment.
Frequently Asked Questions
