Prepared for preliminary research by the RIVO OPTICAL knowledge desk. Confirm cable count, splice capacity, sealing class, tray layout, protection sleeves and installation requirements against current standards and product documentation.

Yes, galvanized cable tray supports are typically galvanized to match the corrosion resistance of the trays themselves.

Galvanized cable tray systems are designed for durability and corrosion resistance, and this protection extends to the supporting components such as brackets, hangers, and other structural supports. These supports are usually made from pre-galvanized or hot-dip galvanized steel, ensuring that the entire system, not just the tray, is protected against rust and oxidation in both indoor and outdoor environments . Types of Galvanization for Supports:

  • Pre-galvanized (PG) steel: Coated with a thin layer of zinc, suitable for dry indoor environments like offices or factories. The coating thickness typically ranges from 12 to 20 microns .
  • Hot-dip galvanized (HDG) steel: Fully immersed in molten zinc, creating a thick, durable coating (65–85 microns) that protects against moisture, rain, and salt air, making it ideal for outdoor or high-humidity installations . Using galvanized supports ensures that the entire cable tray system maintains structural integrity and corrosion resistance, preventing premature rusting that could compromise safety or require frequent maintenance. When selecting a system, it is important to verify that both the trays and their supports are appropriately galvanized for the intended environment . In summary, for a fully durable and corrosion-resistant installation, both the cable trays and their supporting structures should be galvanized, with the choice of pre-galvanized or hot-dip galvanized steel depending on environmental exposure and load requirements.
