Cable tray crossarms are typically metallic for galvanized steel types, while composite crossarms can be supplied in custom colors with UV-resistant coatings.Galvanized Steel Crossarms

Most cable tray crossarms made from galvanized steel are finished with a hot-dip galvanization, giving them a metallic silver appearance. This coating primarily provides corrosion resistance rather than aesthetic color, so standard galvanized crossarms are generally not available in other colors .

Composite Crossarms

For composite crossarms, such as those used in transmission and distribution applications, manufacturers like Shakespeare offer custom colors upon request. These crossarms are coated with urethane layers that provide triple UV protection, ensuring long-lasting color retention and durability even under harsh environmental conditions . This allows utilities to select colors for visual identification, safety, or aesthetic purposes.

Summary
  • Galvanized steel crossarms: Metallic silver (standard), primarily for corrosion protection.
  • Composite crossarms: Custom colors available with UV-resistant urethane coatings, suitable for long-term outdoor exposure and visual differentiation . For specific color options, it is recommended to contact the manufacturer directly, as custom colors may vary depending on the material and coating process.
