Corrosion-resistant cable tray manufacturing process
The typical process for FRP cable trays is pultrusion, in which continuous strands of fiberglass are pulled through a resin bath, and then pulled through a heated die that shapes the pultrusion and cures the resin to a final product. Material Selection The first step in cable tray manufacturing is choosing the right material. This white paper compares the High Resistance (HR) and Hot-Dip Galvanising (HDG) solutions and highlights the new High Resistance range, ZnAl. — 01 A surface veil is applied during the pultrusion process to ensure a resin rich surface for superior corrosion resistance as well as an ultraviolet exposure barrier. The initial processing involves cutting raw steel sheets to precise dimensions using advanced laser cutting or punching equipment.
