FRP questions, answered

FRP stands for fibre-reinforced plastic, also written fiber reinforced plastic and often called GRP or fibreglass. It's made of glass fibres set in a resin, usually polyester. The glass gives strength, the resin binds it and holds the shape, and a gelcoat on the face gives colour and protection.

Most of our products are made by hand lay-up. A mould is waxed, gelcoat is laid into it, then layers of glass-fibre mat are laid in and wetted with resin until the part is thick enough. Once cured, the part comes out of the mould and is trimmed and finished.

For its weight, yes. FRP is strong and tough, and it doesn't rust or rot. Decorative elements such as columns, arches and cornices are shells, though, and aren't meant to carry building loads.

FRP doesn't rust, rot or absorb water, so it lasts a long time outdoors. What weathers is the surface: over the years a gelcoat or paint can lose gloss, and it can be polished or recoated.

Both use glass fibre. GRC (glass fibre reinforced concrete) is cement-based: heavier, stone-like and non-combustible. FRP is plastic-based: much lighter, smoother, and any colour. Our sister division, GRC Bangalore, makes GRC, so we can tell you which suits your project.

No. FRP is combustible. Fire-retardant resins improve how it behaves in a fire. Where fire rules apply, such as facades on tall buildings, we ask for your requirements before choosing materials.

In strong sun, colours can fade and gloss can dull over time. UV-resistant gelcoats and paints slow this down, and the surface can be restored by polishing or repainting.

Yes. Our team installs column covers, cornices, arches, facade panels, gutters and waterproofing. We can also supply only, with fixing details for your contractor.

Wash it with water, a mild detergent and a soft cloth or brush. Avoid abrasive cleaners and solvents, which dull the gelcoat.

Yes. Chips and cracks are filled with resin and gelcoat and polished back. Larger damage is cut out and patched with new laminate.

Yes, with a suitable primer. Most of our products come in a coloured gelcoat, so painting is only needed to match an existing finish.
