Unitrunk Cable Tray

The latest Zinc Magnesium (ZM) coated steel cable tray from Unitrunk enhances corrosion resistance beyond standard galvanised steel through a dense, zinc-based protective layer. This innovative coating uniformly encapsulates the tray, ensuring edge-to-edge protection, even over perforations and scratches. It offers streamlined lead times and cost efficiencies, coupled with a reduced environmental impact, aligning with the technical and operational demands of electrical projects.




About Unitrunk ZM



The innovative Zinc Magnesium (ZM) coated steel cable tray system from Unitrunk stands out for its exceptional corrosion resistance. Unlike traditional post-galvanised steel, the ZM coating forms a dense, protective film that safeguards the entire tray, including edges, perforations, and scratches, enhancing protection while offering environmental benefits and reduced lead times.

What is the difference between heavy duty and medium duty cable tray?

Heavy duty cable trays are built for demanding applications, capable of supporting heavier cable loads and enduring tough environmental conditions. Medium duty cable trays are intended for lighter loads and more moderate environments, providing a balance between durability and cost-effectiveness.

What is the British standard for cable trays?

The British Standard for cable trays is BS EN 61537:2007, which specifies requirements and tests for cable tray systems and cable ladder systems used to support and accommodate cables in electrical and communication installations. This standard ensures quality and safety in cable management systems. All Unitrunk trays conform to this standard.

What is BS EN 10346?

BS EN 10346:2015 sets out the criteria for pre-galvanised mild steel used in cable trays, ensuring adherence to quality standards in the manufacturing of cable management systems. This standard guarantees that the material meets specific requirements, enhancing the reliability and durability of cable tray systems.
