When carbon steel rusts and stainless still corrodes, fiberglass holds up — corrosion-proof grating, walkways, and structures for acid plants, chemical processing, and oil & gas.
Aggressive chemicals defeat steel — and even stainless
- Chemical attack. Acids, alkalis, solvents, chlorides, and fumes corrode carbon steel quickly and degrade even stainless and coatings over time.
- Constant replacement. Corroded grating, walkways, and supports in process areas mean repeated shutdowns and spend.
- Safety in harsh areas. Failing steel structures over containment and process equipment are a hazard.
- High maintenance. Coatings need constant inspection and repair.
FRP built for corrosive process environments
- Broad chemical resistance — vinyl-ester FRP resists a wide range of acids, alkalis, and solvents where stainless is costly and still vulnerable.
- The harsher the environment, the bigger the advantage — FRP doesn’t pit, rust, or scale.
- Lightweight & non-conductive; fire-retardant resin options for code-driven areas.
- Static-control options — conductive / static-dissipative grating available where ESD or static is a concern.
- Low maintenance, long life — lower total cost of ownership.
What we supply

Why FRP costs less over its life
In acid and chemical service, coated and stainless steel still corrode. FRP resists — and lasts.
| Over 25 years (illustrative) | Steel / Stainless | Crimar FRP |
|---|---|---|
| Resistance to acids/alkalis/solvents | Limited / degrades | Excellent |
| Coating inspection & repair | Recurring | None |
| Replacement | Multiple times | Installs once |
| Process downtime to replace | Repeated | One-time install |
| Fire / static options | Limited | FR & static-dissipative grades |
| 25-yr total cost of ownership | Higher | Lower |
The decisive line: one avoided failure, shutdown, or incident dwarfs the material premium. You aren’t buying grating — you’re buying the elimination of a failure mode.
Why Crimar
Crimar Composites is the pultrusion arm of the Crimar group, serving industrial clients since 1988 — US-based engineering and customer support, FRP manufacturing in Los Angeles, USA, backed by global production capacity, and a group capability spanning pultruded products and ASME RTP-1 hand lay-up FRP. For chemical service, the group also fabricates ASME RTP-1 tanks, ductwork, and scrubbers — so one supplier covers everything from grating to full FRP vessels.
