GRP Gratings: Totally Resistant to Corrosion
Certain applications are not suitable for metal gratings because of corrosive environments and they will soon begin to rust. Gripclad GRP Grating provides a modern high specification alternative to traditional galvanised steel for walkways, platforms and gantries. GRP Grating is the lowest life cycle cost and it weighs considerably less than conventional metal gratings because it is easier to and less expensive to transports, install and remove if required.
There are no costs associated with heavy lifting, cutting or welding and GRP Grating allows opportunities for increased safety since it offers an integrated anti-slip surface unlike metal grating.
It offers lightweight, exceptional strength, non corrosive, non magnetic, non-conductive, chemical resistant, and UV Stable for the 21st century marine industry.

Where were the GRP Gratings used
We cut all the Anti-Slip Gritted Grating in accordance with the clients specification. Our GRP 38mm thick Open Mesh Gritted Grating with a square mesh 38mm x 38mm was delivered ready for their own maintenance team to install on various areas of the dredgers which required replacing the old rusted and warped metal grating.
The Grating was used on Port Side Draghead Catwalks, Stbd Aft Wing Athwartship, Stbd Aft Bridge, Pump Room Voids, Ecab Platforms and Feeder Hoppers.
Instant Improvement Proven Results
We cut all the Gripclad GRP Grating for you, ready for instant installation on all your platforms, catwalks, gantries for a safe working environment. No Welding, No Hot Works, No Fuss...just simple fixing with well designed clip and clamp assembly.
Unlike metal grating which will eventually deform and warp, the impact resistance of GRP Grating allows repeated deflection without permanent deformation. Metal expands and contracts at a much higher rate than GRP causing unseen stress fractures and eventually, through time, bending and breaking.
When we receive an enquiry regarding the use of GRP Grating all aspects of its intended use are always considered. What is the Load bearing, Environment, Potential Impact, Possible Spillage Contamination, Maintenance regime, Non-conductivity, Fire integrity and even Colour.
Tarmac Marine realised that GRP Grating is the long term solution in Salt Sea and Air Environments.
The best way is the GRP way.

The perfect solution in salt air & water environments
The Result?
"The Grating is excellent and as a result we shall soon be ordering more. We have recently carried out repairs on a large pump; the impeller being over a metre across and experienced no issues working on the grating with 3 men. We are more than pleased with this product"
