Installation Method of German Galvanized Cable Trays

German galvanized cable trays are installed using standardized support systems, proper mounting brackets, and adherence to DIN EN 61537 and DIN 4102 standards to ensure mechanical stability and corrosion protection.Material Preparation and InspectionBefore installation, all cable trays, ladders, and fittings should be inspected for damage and compliance with approved material submittals. Unsuitable or damaged materials must be removed from the site. Cable trays are typically stored horizontally on flat surfaces with timber supports at 1-meter intervals and protected from moisture and direct sunlight to prevent corrosion or deformation .Support and Mounting SystemsGerman galvanized cable trays often use standard support constructions such as the RS 60 system, which includes ceiling-mounted, cantilever, or pendant brackets. The spacing of supports depends on tray width, edge height, and permissible cable load. For example, RS cable trays with a 60 mm edge height are used in widths from 100 to 300 mm, with couplers and brackets designed to maintain structural integrity . Ceiling suspension can be achieved using M10 threaded rods, TKS pendant brackets, or cantilever brackets with appropriate adapters .Installation ProcedureReview Shop Drawings: Confirm tray layout, lengths, and locations according to approved drawings .Prepare Tools and Equipment: Ensure all tools comply with contract requirements and are suitable for galvanized steel installation .Assemble Supports: Install ceiling, wall, or floor supports according to the standard support construction, ensuring proper alignment and spacing .Install Cable Trays: Place trays on supports, connect sections using couplers, and secure with bolts or clamps. Ensure trays are level and properly aligned .Check Load and Clearance: Verify that the trays can support the intended cable weight and maintain required clearances for ventilation and safety .Grounding and Bonding: Ensure all metallic trays are properly grounded to prevent electrical hazards .Corrosion ProtectionGalvanized cable trays are protected by a zinc coating, which forms a sacrificial layer that corrodes preferentially, protecting the steel underneath. The thickness of the zinc layer depends on the galvanization method (electro-galvanized or hot-dip) and directly affects corrosion resistance. In wet or industrial environments, the zinc layer gradually converts to zinc carbonate, forming a durable protective patina .Compliance and StandardsInstallation must comply with DIN EN 61537 for cable support systems and DIN 4102 Part 12 for fire safety and mechanical load requirements. CE marking indicates conformity with European directives, and all components should meet the permissible cable dead weight and fastening spacing specified in the standards .Final ChecksAfter installation, perform a visual inspection to ensure proper alignment, secure connections, and absence of damage. Verify that all trays are level, adequately supported, and ready for cable routing . By following these steps, German galvanized cable trays can be installed safely, efficiently, and in compliance with industrial and European standards.
