Fiberglass conduit and duct for cable and electrical protection in corrosive and energized environments — won’t rust, won’t conduct, lightweight, long lengths. Made in the USA.

The problem with steel, galvanized, and PVC conduit
- Steel and galvanized conduit corrodes in chemical, coastal, and buried service.
- Metal conduit conducts — a hazard around energized systems and a grounding/EMI concern.
- PVC degrades under UV and temperature and can sag in long runs.
- Heavy metal conduit is slow to install and adds weight.
The Crimar FRP solution
- Non-conductive & RF-transparent — no stray current paths or EMI interference.
- Corrosion-proof — chemical plants, coastal, and direct-buried service.
- UV-stable and wide temperature range — outdoor and harsh duty.
- Lightweight, long lengths — fewer joints, faster installs.
- High strength — supports long spans on cable runs and tray.
What we supply
- FRP conduit and duct in a range of diameters
- Elbows, couplings, and fittings; custom lengths
- For power, telecom, instrumentation, and signaling
- Above-ground, cable-tray, and direct-buried applications
Lower total cost of ownership
| Over 25 years (illustrative) | Steel / metal | Crimar FRP |
|---|---|---|
| Corrosion / replacement | Recurring | None |
| UV / temperature failure | Possible (PVC) | Resistant |
| Conductivity / EMI | Conductive (metal) | Non-conductive |
| Lifetime cost | Higher | Lower |
One avoided corrosion failure, shock incident, or unplanned outage can outweigh the entire material premium. You are not just buying a product — you are eliminating a failure mode.

Frequently Asked Questions
How is FRP conduit better than steel or PVC?
It will not corrode like metal, will not conduct or create EMI, and resists the UV and temperature degradation that affects PVC — in a lighter, long-length product with fewer joints.
What diameters are available?
FRP conduit and duct are produced in a range of diameters with matching fittings and custom lengths. Tell us your run and we will recommend a size.
Can it be direct-buried?
Yes — FRP conduit is suited to above-ground, cable-tray, and direct-buried installations in corrosive ground and chemical environments.
Is it non-conductive?
Yes — fiberglass conduit is electrically non-conductive and RF-transparent, eliminating stray current paths and interference.
