Gelcoat Panel Structure
FRP gelcoat panels are built from two integrated layers, engineered to work together for long-term outdoor and industrial performance.
Gelcoat Layer — provides a smooth, UV-resistant, weatherable surface.
Fiberglass-Reinforced Resin Layer — delivers structural strength, stiffness, impact resistance, and corrosion resistance.
Materials Guide
Core Material Comparison
For sandwich panels, core material selection directly affects insulation performance, structural strength, and weight.

FAQ
Frequently Asked Questions
Gelcoat panels are solid FRP panels with a decorative and protective gelcoat surface, typically used for surface or decorative applications. Sandwich panels combine an FRP skin with an insulating or structural core material, suited for applications requiring insulation or added structural strength.
It depends on your priority — PU and XPS cores are best for insulation-focused applications like refrigerated transport, PP honeycomb suits structural floor/roof panels, plywood offers cost-effective ease of fabrication, and PET core is the best choice for projects prioritizing recyclability or higher-strength requirements.
