Chalco fiberglass honeycomb panels are lightweight, high-strength sandwich panels designed for engineering-grade structural applications. They consist of fiberglass face sheets bonded to a honeycomb core.
Compared with conventional FRP lightweight panels using PP or paper honeycomb cores, these panels provide higher load capacity, structural rigidity, and long-term stability, making them suitable for transportation, prefabricated buildings, ship interiors, and industrial equipment enclosures.

Key Features and Advantages of Chalco Fiberglass Honeycomb Panel
- With high structural strength, aluminum honeycomb offers superior load-bearing capacity compared to PP and paper honeycomb, and is less prone to creep and deformation.
- Combining lightweight design with high flatness, it is suitable for large-size wall panels, ceiling panels, and flooring.
- Epoxy fiberglass is corrosion-resistant, impact-resistant, and can be used stably in the range of -40°C to +90°C.
- Flame-retardant structures are available to meet the safety requirements of transportation and public buildings.
- It has strong processing adaptability, can be cut and edge-sealed, and can be used in conjunction with a variety of system structures.
Why Choose Aluminum Honeycomb Core Instead of PP or Paper?
Higher structural strength: Aluminum honeycomb has compressive and bending strength that is about 3–5 times that of PP honeycomb, making it suitable for load-bearing structural panels.
No creep or deformation: PP and paper honeycomb are prone to sinking or creeping under long-term loads, while aluminum honeycomb can maintain long-term stability.
It has better temperature resistance: it can be used reliably in the range of –40°C to +90°C, while PP is prone to softening at high temperatures and cracking at low temperatures.
Stable dimensions and flatness: The regular hexagonal structure of the aluminum honeycomb is suitable for large-size wall panels, ceiling panels, floors and other scenarios with high flatness requirements.
Adaptable to a wider range of engineering applications: It can withstand structural loads and can be used in more demanding applications such as vehicle floors, equipment housings, industrial partitions, and cabin structures.
