What is a Fiberglass(FRP) Sheet?
Fiberglass Sheet (thermosetting glass fiber reinforced plastic) combines glass fiber and thermosetting resin, with a gel-coated surface. As a new environmentally friendly material, it offers greater toughness than steel and aluminum products.
It resists cracking, deformation, and heat transfer even under extremely low or high temperatures. As a result, many industries widely use FRP, including dry truck bodies, wall decorative covers, refrigerated truck bodies, RV side panels, and cold storage walls.

Structure of FRP Sheet
Felt-based Fiberglass sheet
- Resin+Fiberglass mat: Chopped fiber, continuous fiber mat, stitched mat, etc.

Advantages: Smooth surface, lower cost.
Cloth-based Fiberglass Sheet
- Resin+Fiberglass cloth: Mesh cloth, square cloth, plain cloth, axial cloth, etc.

Advantages: High strength and stable performance.
Gelcoat Layer | Gelcoat is a protective surface coating that provides a smooth, shiny finish to FRP surfaces, making them more aesthetically pleasing |
Fiberglass Reinforcement Layer | High-quality thermosetting resin + fiberglass felt or fiberglass cloth |
Non-woven Fabric Layer | The non-woven fabric serves as a connecting layer, and FRP and other materials can be tightly bonded by spraying glue. |
Features
- Extremely lightweight
The relative density is usually between 1.5 and 2.0, which is only 1/4 to 1/5 of carbon steel.
- Extremely strong
The tensile strength of glass fiber is close to that of carbon steel.
- Corrosion resistance
Glass fiber can resist corrosion from a variety of chemical media, including acids, alkalis, salts and most chemicals.
- Electrical insulation
Glass fiber has good electrical insulation properties and is suitable for use as an insulating material.
- Thermal insulation
FRP transfers heat slowly, which gives it significant advantages in places that require heat preservation or insulation, such as cold storage, storage tanks, HVAC equipment, etc. FRP has a low thermal conductivity of 1.25~1.67kJ/(m·h·K) at room temperature, which is only 1/100~1/1000 of metal and is an excellent thermal insulation material.
- Aesthetics
FRP sheets can be made of anti-aging, weather-resistant, and UV-resistant gel-coated resins, with a smooth and beautiful surface and bright color.
- Easy to process
FRP sheets offer excellent plasticity and processability, allowing you to shape them into various products of different sizes through molding, injection molding, and manual processes.
- Eco-friendly
FRP sheets do not contain volatile and corrosive substances and are a recyclable product.
Benefits
