FROM WITHIN
Every SOLIDO cover is a precision-engineered composite system. Five bonded layers working as one — absorbing load, resisting corrosion, enduring decades of urban stress.

What Is GRP?

GRP Cross-Section
Glass Fibre + Resin Matrix
Glass Reinforced Polymer
PRV · Fibre de verre + Résine polyester
GRP — also known as fibreglass or PRV (plastique renforcé de verre) — is a composite material formed by embedding glass fibres within a polymer resin matrix. The result is a material that combines the tensile strength of glass with the chemical resistance and mouldability of polymer.
Unlike steel or cast iron, GRP does not corrode, rust or degrade when exposed to moisture, acids, salts or urban chemicals. It is electrically non-conductive, RF-transparent, and has no scrap metal value — making it inherently theft-resistant.
