Before assembly, review construction drawings and conduct an on-site inspection to determine the tray route, installation height, support spacing, and any bends or junctions required . Ensure the load-bearing capacity of the fiberglass tray matches the cable quantity to prevent deformation or loosening . Check all materials, including tray sections, supports, connectors, and fasteners, for cracks, broken edges, or fiber delamination . Protect trays during transport from impacts, drops, or prolonged sun exposure .
If field cutting is necessary, use a circular power saw with an abrasive cut-off wheel or a hack saw with 24–32 teeth per inch . Drill fiberglass like hardwood using standard twist drills, and seal any cut or drilled surfaces with compatible resin . Firmly support the material during cutting to prevent chipping . Carbide-tipped saw blades and drill bits are recommended for large quantities .
Install supports according to design specifications, ensuring spacing does not exceed the distance between splice plates . When hanging from beams, use appropriate clamps and fully engage all-thread rods to meet load ratings . Torque nuts to a snug 3–4 ft.-lbs . Supports should be level and stable before tray installation.
Install fiberglass trays section by section, connecting each segment with splice plates, bolts, and washers . Ensure trays are level, joints are aligned, and gaps are minimal . For turns, rises, or branches, use standard GRP fittings such as horizontal bends, vertical bends, tees, and crosses . Avoid on-site makeshift splicing to maintain structural integrity .
Once trays are assembled, add covers to protect against dust, falling objects, and mechanical damage . Ensure all fasteners are tight, and conduct a full inspection to verify joint security and support stability before laying cables . Maintain safe distances from electrical equipment to prevent interference or hazards . For wall or floor penetrations, use protective sleeves and fire-stopping materials .
Label, sort, and bundle cables before installation, using flame-retardant ties . Allow slack for thermal expansion and contraction . Design a grounding system as required to ensure safety and compliance with electrical standards . By following these steps, fiberglass cable trays can be safely and effectively assembled, ensuring long-term structural integrity and reliable cable management.
