Riveting Methods for Fiberglass Cable Trays

Riveting fiberglass cable trays requires pre-drilling, using corrosion-resistant rivets, and following proper torque and alignment practices to ensure a secure and durable installation.

Tools and Materials Needed

Fiberglass cable tray rivets (corrosion-resistant, compatible with your tray system) Drill with standard twist drill bits suitable for hardwood or carbide-tipped for large quantities Rivet gun or hand riveterProtective resin to seal any drilled or cut edges Clamps or supports to hold the tray steady during installation Step-by-Step InstallationMark and Pre-Drill HolesIdentify the locations for rivets along the tray and fittings. Drill holes using a standard twist drill bit, treating fiberglass like hardwood. Ensure the tray is firmly supported to prevent chipping or cracking.

Seal Cut or Drilled Edges

Any surface that has been drilled, cut, or sanded should be sealed with a compatible resin to maintain structural integrity and prevent moisture ingress.

Insert Rivets

Place the fiberglass rivet through the pre-drilled hole. Ensure the rivet is fully seated and aligned with the mating surface.

Secure Rivets

Use a rivet gun to expand the rivet and lock it in place. Apply consistent pressure to avoid over-tightening, which can crack the fiberglass.

Check Alignment and Torque

Ensure all tray sections and fittings are properly aligned. For threaded connections or clamps used in conjunction with rivets, follow recommended torque values (e.g., 3–4 ft-lbs for thread rod nuts) to maintain load safety.

Support and Spacing

Maintain proper support spacing according to the tray manufacturer's guidelines (typically, the distance between supports should not exceed the distance between splice plates).

Best Practices

Use original manufacturer accessories to maintain warranty and system integrity. Avoid using fiberglass trays as walkways or for personnel support; they are designed solely for cable support. For long covers or wide trays, consider additional rivets or clamps at the center to prevent sagging.

By following these steps and using the correct rivets and tools, you can ensure a durable, corrosion-resistant, and safe installation of fiberglass cable trays.
