GRP sandwich panels are ultimate in strength and are made by bonding 4mm anti-slip flooring sheets to the top and the bottom of a sheet of standard mesh grating. This gives it an added rigidity which makes it an ideal solution for vehicular access and can be used to bridge trenches and gullies with confidence. They weigh far less than a steel or concrete equivalent, meaning it costs less to transport and install and it lasts longer.
GRP sandwich panels have all the benefits of GRP including low maintenance, corrosion resistance and chemical resistance whilst providing weather-proof protection for what lies below. If you require a truly water-resistant cover, choose our Interlocking Panels which can be sealed.
We also have a Solid Top with Mesh Bottom option too.
See our Solid Top in use in our case study Safe at Sea.
