Mesh cable trays are made by cutting, welding, and forming steel or stainless steel wires into a durable, ventilated grid structure suitable for cable management.

Material Selection

Mesh cable trays are typically made from high-quality steel or stainless steel, chosen based on environmental conditions such as indoor or outdoor use. Common finishes include galvanized steel, hot-dip galvanizing, powder coating, or stainless steel polishing to enhance corrosion resistance and durability .

Cutting and Preparation

The production begins with cutting wires to precise lengths using laser cutting machines or shearing tools. This ensures accuracy and minimizes material waste. Both longitudinal and cross wires are prepared according to the tray's design specifications, including width, height, and grid size .

Welding and Mesh Formation

The wires are assembled into a mesh using automated welding machines. Horizontal and vertical wires are fed into the welding system, where precision welding creates strong, durable joints. This process can weld multiple mesh panels simultaneously. The welded mesh forms the basic cable tray panel .

Bending and Shaping

After welding, the mesh panels are placed in bending machines to form the tray's final shape, including straight sections, bends, tees, crosses, and reducers. The open mesh design allows for easy cable routing and ventilation, while the bending process ensures the tray fits installation requirements .

Surface Treatment

Finally, trays undergo surface treatments to improve longevity and resistance to environmental factors. Options include galvanization, powder coating, or stainless steel finishing, depending on whether the tray will be used indoors, outdoors, or in corrosive environments .

Customization and Standards

Mesh cable trays can be customized in widths, depths, and lengths to meet project specifications. They are designed to comply with industry standards for load-bearing capacity, safety, and temperature tolerance, typically ranging from -40°C to +150°C .

Summary

The manufacturing of mesh cable trays involves material selection, precise cutting, automated welding, bending, and surface finishing. This process produces a lightweight, ventilated, and durable tray that simplifies cable management, supports complex installations, and ensures long-term reliability in various industrial, commercial, and residential applications .
