  • How to determine the corrosion resistance level of cable trays

    How to determine the corrosion resistance level of cable trays

    The corrosion resistance of the cable trays is based on the UNE-EN IEC 61537 standard and is verified by the continuous salt spray test (ISO 9227). Both procedures are certified and audited by AENOR, which guarantees full compliance with national and international standards. Choosing the right anti-corrosive cable trays is essential for preventing damage and maintaining. In the cable tray industry, corrosion protection is critical because cable trays, supports, and related components are often exposed to harsh environmental conditions. These trays not only organize and protect cables but also ensure long-term reliability. Grade C8 represents one of the highest levels of environmental aggressiveness and requires specific protective treatments to ensure the integrity and safety of the system. When used in wet areas such as food factories, the wrong tray is picked and the rusting will be rapid. This is a comparison of Hot-Dip Galvanized, Stainless Steel, and Aluminum.
