100mm wide cable tray dimensions

A standard 100mm cable tray typically has a width of 100mm, a depth of 25mm, and a length of 3 meters, with variations depending on duty class and material.Standard DimensionsWidth: 100mm (nominal width for medium and light-duty trays) Depth/Height: Commonly 25mm for medium-duty trays, though heavy-duty trays may have greater sidewall heights for increased load capacity Length: Standard lengths are 3 meters per section, allowing modular installation Material Thickness: Varies by duty class; light-duty trays are thinner, medium-duty trays are pre-galvanised steel, and heavy-duty trays are zinc-coated galvanised steel for structural strength Duty Class VariationsLight Duty: Suitable for small cables or low-load applications; easy to cut and shape Medium Duty: Pre-galvanised steel, 25mm return flange, punched holes at 25mm centers; ideal for industrial and commercial installations Heavy Duty: Designed for larger cable loads, wider trays up to 900mm, solid or perforated options, zinc-coated for corrosion resistance Additional ConsiderationsTray Type: Ladder, perforated, or channel trays affect usable cable area and heat dissipation Cable Fill: The nominal width does not always equal usable area; sidewall height and perforation patterns reduce effective space Customization: Special sizes, bespoke designs, and powder-coated finishes are available for specific project requirements When selecting a 100mm cable tray, consider cable type, load, installation environment, and future expansion to ensure compliance with standards and safe operation.
