Offshore and marine platforms specify FRP grating for saltwater corrosion resistance, low weight and fire retardancy — pultruded FRP with FR and UV-stabilized resin is the marine standard.
- Best for: offshore decks, helidecks, ships and coastal walkways
- Specify when: salt spray, fire and weight matter — pultruded FR + UV resin
- Key spec: FR (flame-retardant), UV-stabilized, ASTM load class
FRP Grating for Offshore & Marine
Offshore platforms and marine environments are the most corrosive settings on Earth. FRP grating is the material of choice for these demanding applications.
Why FRP for Marine/Offshore?
- Immune to saltwater corrosion (unlike steel which rusts in months)
- UV resistant formulations for sun exposure
- Non-conductive - electrical safety on platforms
- Lightweight - reduces topside weight
- Low maintenance - no painting in hard-to-reach areas
- Fire retardant options available
Recommended Specifications
Resin: Vinyl ester with UV stabilizers (standard for marine)
Grating Type: Pultruded for long spans, molded for general areas
Surface: Grit surface for wet/heaving deck areas

Frequently Asked Questions
FRP (Fiberglass Reinforced Plastic) grating is a molded or pultruded fiberglass composite grid used for corrosion-resistant walkways, platforms and floorings. It combines glass fiber reinforcement with thermoset resin (polyester, vinyl ester, epoxy) for superior strength-to-weight ratio, zero rust and 20+ year service life.
