FRP (GRP / fiberglass) cable tray is non-conductive, non-corrosive and roughly a third the weight of steel. It is specified for chemical plants, offshore platforms, water treatment and coastal installations where metallic trays would need constant maintenance.
FRP tray is manufactured by pultrusion using continuous fibreglass rovings with vinyl ester or isophthalic polyester resin. The result has high strength-to-weight ratio, excellent dielectric properties and outstanding resistance to salt mist, acids and alkalis.
YITORCH supplies FRP ladder tray and its complete fitting range — elbows, tees, crosses, 135° risers, width reducers, dividers and cover clamps — so entire corrosive-area runs can be supplied in composite rather than mixing materials.
Standard stock range; custom sizes, slot patterns and hole layouts produced on request.

FRP does not rust, pit or need repainting, which typically removes the maintenance cycle required by coated steel tray in chemical areas.
The composite structure has no electrical continuity path, reducing touch voltage risk and making it suitable where induction heating is a concern.
At roughly one third of steel weight, FRP is handled without cranes and cut on site with standard tools.
ASTM E84 Class 1 flame spread ratings and self-extinguishing ASTM D635 grades are supplied where project specifications require them.

Not sure which type or thickness suits your load? Read the Cable Tray Buying Guide — covers type selection, finish comparison, sizing rules and international standards.
FRP has higher strength-to-weight ratio but lower absolute stiffness, which means support spans are shorter. As a rule of thumb the span is around 1.5–2.0 m for FRP versus 2.0–3.0 m for steel; we size this for your load.
Isophthalic polyester covers most industrial and marine applications. Vinyl ester is recommended where concentrated acids, solvents or high temperature are present — send us your chemical exposure list and we confirm.
Yes, fire-retardant grades meeting ASTM E84 Class 1 (flame spread index ≤ 25) and ASTM D635 self-extinguishing requirements are available.
Yes. FRP covers with GK / MK clamps and divider strips are stocked so power and control cables can be separated in the same route.
Standard profiles are dispatched in 10–15 days; resin-specific or non-standard sizes typically take 20–30 days due to curing schedules.
