Tools for making fiberglass cable trays

Fiberglass cable trays require specialized cutting, drilling, and assembly tools to ensure clean edges, structural integrity, and safe installation.Cutting ToolsFiberglass trays can be cut using circular power saws with abrasive cut-off wheels or hack saws with 24–32 teeth per inch for smaller jobs . For large-scale production, carbide-tipped saw blades are recommended to maintain sharpness and prevent excessive heat that can soften the resin and create ragged edges . Always support the fiberglass firmly during cutting to avoid chipping or cracking.Drilling ToolsDrilling fiberglass is similar to drilling hardwood. Standard twist drills are sufficient for most applications, but carbide-tipped drill bits are preferred for high-volume work . After cutting or drilling, any exposed edges should be sealed with a compatible resin to maintain corrosion resistance and structural integrity .Assembly and Fastening ToolsTorque wrenches: A snug torque of 3–4 ft.-lbs. is typically sufficient for thread rod nuts .Clamps: B-Line BFPU751 series clamps or equivalent provide secure engagement for hanging trays from beams .Threaded rods: Fully engage all-thread rods in clamps to meet load ratings .Safety and HandlingFiberglass is lightweight but can produce dust and sharp edges. Use gloves, eye protection, and dust masks during cutting and drilling . Pultruded fiberglass trays are non-conductive, corrosion-resistant, and self-extinguishing, making them safer for electrical installations .Additional ConsiderationsPultrusion vs. pressed trays: Pultruded trays offer higher strength-to-weight ratios and are easier to handle .Surface treatment: A resin-rich surface veil improves corrosion resistance and UV protection .Installation environment: Fiberglass trays are suitable for offshore, chemical, and humid environments due to their resistance to chemicals, seawater, and fire . By using the correct tools and following proper handling procedures, fiberglass cable trays can be cut, drilled, and installed efficiently, ensuring long-term durability and safety in industrial or commercial applications .
