If you are planning a facade, a statue, a ceiling medallion or a wedding entrance, you will hear two terms again and again: GRC and FRP. Both are used to reproduce the look of carved stone, plaster and marble at lower weight and cost, but they are different materials with different strengths. This guide explains the difference in plain language so you can choose the right one for your project.
What Is GRC?
GRC stands for glass fibre reinforced concrete. It is a cement-based mix reinforced with glass fibres and cast in moulds. Because it is cement-based, it behaves much like concrete: it is rigid, takes paint and render well, and does not burn.
What Is FRP?
FRP stands for fibre reinforced plastic (also called fibreglass or GRP). It is made by layering glass fibre with resin in a mould. The result is a hollow, very light shell that can carry fine carved detail and can be painted in almost any finish, including stone, marble and gold looks.
GRC vs FRP at a Glance
| Feature | GRC | FRP |
|---|---|---|
| Base material | Cement with glass fibre | Resin with glass fibre |
| Weight | Heavier than FRP, lighter than solid concrete | Very light |
| Fire behaviour | Non-combustible | Resin can burn unless a fire-retardant grade is used |
| Fine detail | Good | Excellent for ornate carving |
| Best for | Permanent building facades, columns, cornices | Statues, wedding decor, medallions, temporary or large decor pieces |
| Transport and installation | Needs stronger fixings and handling | Easy to move and install |
When to Choose GRC
- Permanent exterior cladding, columns and cornices on a building.
- Projects where fire rating is a requirement.
- Elements that must look and behave like real render or stone over many years.
When to Choose FRP
- Statues, fountains and garden sculptures that need to be moved or placed on terraces and balconies.
- Wedding gates, stage backdrops and event decor that are transported and reused.
- Ceiling medallions and wall panels with ornate detail.
- Large pieces where weight and shipping cost matter.
Questions to Ask Before You Order
- Will the piece stay outdoors permanently or move between venues?
- Does the venue or building need a specific fire rating?
- How will it be fixed to the wall or ground, and who installs it?
- What finish do you want, and does it come with a protective coating for sun and rain?
Material choice affects weight, finish and cost, so share your use case early. Final suitability always depends on the exact design, size and site conditions.

Frequently Asked Questions
Is FRP weatherproof?
Yes, FRP does not rust or rot, and a UV-resistant coating helps the finish last outdoors. Ask about the coating for pieces in strong sun.
Is GRC heavier than FRP?
Yes. GRC is cement-based and heavier, so it needs stronger fixing. FRP is hollow and much lighter.
Can both be made to a custom design?
Yes. Both are cast from moulds, so shapes, sizes and motifs can be made to your design.
