Salt water is relentless on steel. Marine and offshore structures need flooring and access that shrugs off corrosion, grips when wet and adds as little weight as possible. GRP grating ticks all three boxes, which is why it is used on jetties, pontoons, vessels and offshore platforms across the UK.
Why GRP grating suits marine and offshore
- Corrosion resistance – GRP does not rust or rot in salt water and spray, unlike steel, which slashes maintenance.
- Lightweight – lower weight helps with vessel stability and reduces load on pontoons and elevated structures.
- Anti-slip when wet – the gritted surface keeps grip on decks, gangways and walkways exposed to spray.
- Non-conductive and low maintenance – safer around equipment and far less upkeep over its service life.
Typical applications

Frequently asked questions
Does GRP grating corrode in salt water?
No. GRP does not rust or rot, which makes it well suited to marine and offshore use where steel would corrode quickly.
Is GRP grating slip resistant when wet?
Yes. The gritted top surface is designed to maintain grip in wet conditions, which is important on decks and gangways exposed to spray.
For structural or safety-critical marine applications, confirm the specification with a suitably qualified engineer.
