Cable trays in West Africa are available in ladder, perforated, solid-bottom, and wire mesh types, fabricated from steel, aluminum, or stainless steel, with finishes including hot-dip galvanised, pre-galvanised, powder-coated, and stainless steel options.

Types and Configurations

• Ladder Cable Trays: Feature two longitudinal side rails connected by rungs, ideal for power cables requiring ventilation and heat dissipation .
• Perforated Cable Trays: Solid-bottom trays with perforations for moderate ventilation, suitable for control, communication, and non-heat-producing cables .
• Solid-Bottom Cable Trays: Provide maximum protection from external damage, used for sensitive instrumentation and data cables .
• Wire Mesh/Basket Trays: Lightweight, flexible trays for routing data and low-voltage cables, often used in commercial and IT installations .

Materials and Finishes

• Steel: Most common, available in hot-dip galvanised, pre-galvanised, or powder-coated finishes .
• Aluminum: Lightweight and corrosion-resistant, suitable for humid or coastal environments .
• Stainless Steel (SS 202/304/316): Used in highly corrosive or industrial environments .

Standard Dimensions
