Precision Manufacturing Process

1. Raw Material Selection

The tray starts with high‑strength steel wire, typically Q235 carbon steel or stainless steel grades 304, 316, and 316L. Wire diameters range from 3 mm to 6 mm, ensuring a balance between rigidity and light weight. For maximum corrosion resistance in marine or chemically aggressive environments, stainless steel is the preferred choice.

2. Mesh Forming and Welding

The wires are automatically straightened, cut, and then welded at every intersection using precision resistance welding. This process creates a uniform grid pattern (e.g., 50 × 100 mm openings) without sharp protrusions. Each weld is carefully controlled to avoid surface irregularities that could later damage cable insulation. The result is a flat, stable mesh panel that can be easily cut or bent on site.

3. Surface Treatment – The Key to Outdoor Durability
For carbon steel versions, the mesh undergoes hot‑dip galvanizing (＞60 µm coating thickness), which provides a metallurgically bonded zinc layer that resists rust even after years of outdoor exposure. Alternatively, a heavy‑duty powder coating (＞60 µm) can be applied for indoor‑outdoor use where colour matching or extra chemical resistance is desired. Stainless steel trays are pickled and passivated – a chemical process that removes surface scale and restores the passive oxide layer, delivering outstanding protection against pitting and crevice corrosion.

4. Edge and Cut‑surface Protection
Every cut end or drilled hole is deburred and, for galvanized trays, touched up with zinc‑rich paint. This attention to detail prevents "red rust" from starting at cut edges – a common failure point of lesser products.

5. Accessory Integration
The outdoor mesh tray is designed to work seamlessly with a full set of galvanised or stainless fittings:

Horizontal and vertical bends for changing direction.
Tees and crosses for creating branch runs.
End caps to close open ends and protect cable ends.
Connecting bolts (stainless steel for outdoor use) and support brackets (adjustable wall‑mounted or strut‑type).

All accessories are produced with the same material and surface finish as the main tray, eliminating galvanic corrosion risks. The open grid design allows quick attachment using standard tools, and the modular nature means you can build straight runs, corners, risers, and complex junctions on site without special machinery.

Performance Benefits

Weather resistance

Hot‑dip galvanising or stainless steel construction endures UV radiation, rain, snow, and salt spray.

Ventilation

The open mesh prevents moisture trapping and allows cables to stay cool, reducing thermal degradation.

Cable protection

Smooth wire surfaces and rounded edges prevent abrasion during pulling and vibration.

Adaptability

On‑site cutability and bendability means the tray fits exactly where it is needed, even around obstacles.

Full compatibility

From simple point‑to‑point links to intricate multi‑branch layouts, the matching accessory range makes any configuration possible.

Typical Outdoor Applications

Outdoor telecommunication cabinets and base stations

Industrial plants with overhead or trench cable runs

Parking garages and open‑air stadiums

Coastal infrastructure (ports, desalination plants)

Solar farms and wind turbine interconnection paths

Conclusion

The Outdoor Wire Mesh Cable Tray is more than a passive support – it is an engineered system.

From the selection of corrosion‑resistant materials and precision welding to hot‑dip galvanising or pickling, every step of the manufacturing process is optimised for long‑term outdoor reliability.

When paired with complete accessories – bends, tees, crosses, end caps, bolts, and brackets – it handles any routing challenge while protecting your valuable cables.

Choose the outdoor mesh cable tray for a solution that is as tough as the environment it serves.
