GRP/FRP Honeycomb Panels
Weather-resistant FRP Sheet + High Modulus Honeycomb Core
FRP honeycomb panels (also called GRP honeycomb panels) are lightweight yet strong composite panels. The core of these panels is made of PP (polypropylene) honeycomb, which provides excellent stiffness and strength while keeping weight low. The FRP (Fiberglass Reinforced Plastic) skins bonded to this core provide durability, corrosion resistance, and a smooth surface finish. It was created to replace traditional wood or metal panels and adapt to more application scenarios.
Product Features
Lightweight & High Strength
FRP honeycomb panels are a typical lightweight material providing extremely high strength-to-weight ratio.
Waterproof and moisture-resistant
It doesn’t rot like wood or rust like steel, and it maintains its structural stability in humid and rainy environments.
Structurally Stable
The hard texture of thermosetting FRP combined with the high modulus of polypropylene honeycomb can well maintain the stability of the panel structure and is not easy to bend or deform.
Weather resistance
FRP panels are added with anti-ultraviolet agents, which can withstand long-term exposure to strong ultraviolet rays without fading or decomposition.
Easy to clean
The surface of FRP is not easy to absorb dust, stains, etc., so it is very convenient to wash with water.

FRP Facing – Various Surface Styles
FRP(GRP) Sheet is a high-strength material made of glass fiber and resin matrix through a composite process. It has excellent characteristics such as light weight, high strength, corrosion resistance and aging resistance. Its surface can be processed into various styles, such as glossy, matte, non-slip, embossed, etc.

Lightweight Polypropylene Honeycomb Core
Polypropylene honeycomb is a lightweight, rigid thermoplastic used as the core of sandwich panel structures. Like aluminum honeycomb, it is also recyclable. Different honeycomb cell sizes have different densities and provide different mechanical strengths. Our honeycomb core is made of high modulus thermoplastic polypropylene plastic, which is flexible and not easily deformed.
