Every reputable cable tray manufacturer starts with high-grade steel materials that meet specific industry standards for strength, durability, and corrosion resistance. The initial processing involves cutting raw steel sheets to precise dimensions using advanced laser. The galvanization process is the primary anti-corrosion treatment for cable trays. The quality of the zinc coating directly determines the tray's service life and application scenarios. This white paper compares the High Resistance (HR) and Hot-Dip Galvanising (HDG) solutions and highlights the new High Resistance range, ZnAl. The foundation of quality cable tray production begins with meticulous steel processing and preparation procedures. The anti-corrosion layers on cable trays include hot-dip galvanizing, galvanized nickel, cold galvanizing, powder electrostatic spraying, and more. 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.
