Thickness of light industrial cable trays

For light industrial applications, cable trays typically have a thickness of 1.2 mm to 1.6 mm.Recommended ThicknessLight-duty cable trays, used for LAN, control wiring, or small power systems, generally require a material thickness between 1.2 mm and 1.6 mm. This thickness is sufficient to support the weight of small cables while maintaining structural integrity and preventing sagging over short spans . For longer spans (2.5 to 3 meters), slightly thicker trays may be necessary to avoid deflection, even in light-duty applications. In such cases, a thickness of 2.0 mm or more can provide additional rigidity .Material and Environmental ConsiderationsSteel trays are common for indoor light industrial use, often with a powder-coated or galvanized finish for corrosion resistance .Stainless steel trays of 2.0 mm or higher are recommended in corrosive or outdoor environments, even for light-duty applications, to ensure durability and safety .Aluminum trays may also be used for lightweight installations, offering good corrosion resistance and ease of handling .Standards and ComplianceCable tray thickness should comply with NEMA, NEC, or IEC standards, which categorize trays by duty class (light, medium, heavy). Light-duty trays are designed for smaller cable loads and shorter spans, and adherence to these standards ensures safety, structural reliability, and code compliance .Practical TipsFill trays to 40–50% of their width to allow proper ventilation and future expansion .Consider span length and support spacing when selecting thickness; closer supports allow thinner trays, while longer unsupported spans require thicker trays .For light industrial setups, channel or wire mesh trays are often preferred due to ease of installation and flexibility for small cable bundles . By selecting the appropriate thickness based on load, span, and environment, light industrial cable trays can provide reliable, safe, and long-lasting cable management.
