Belgian cable tray specifications and models

Belgian cable trays are available in ladder, perforated, and mesh designs, made from galvanized or stainless steel, compliant with IEC 61537 standards, and offered in various widths, heights, and load capacities.

Types of Cable Trays

1. Ladder Trays: Designed for heavy-duty applications, ladder trays provide strong support for large cable bundles and allow excellent ventilation to prevent overheating. They are suitable for industrial and marine environments and are often made from hot-dip galvanized or stainless steel .

2. Perforated Trays: These trays feature a perforated bottom to allow air circulation and drainage, reducing the risk of overheating. They are ideal for medium-duty installations and indoor or outdoor use .

3. Mesh Trays: Mesh or wire trays offer flexibility and easy cable routing, especially for complex installations. They are lightweight, allow visual inspection of cables, and are suitable for office, data center, or industrial applications .

Materials and Construction

Belgian cable trays are typically constructed from hot-dip galvanized steel or stainless steel, ensuring durability and corrosion resistance for both indoor and outdoor applications . The trays are designed with rounded edges and perforations to protect cables and facilitate earthing .

Dimensions and Load Capacities
