Weather-resistant FRP
TOPOLOGROUP, as a professional composite sandwich panel manufacturer in China, provides high-quality FRP sandwich panels. The surface of these panels is weather-resistant FRP, which is durable and does not fade. It can adapt to various climate environments such as rain, snow, hail, frost, and exposure. Demand In order to meet the personalized user needs, the color of FRP can be customized (RAL color series), or the surface of FRP can be processed into various patterns and textures. Our technicians will set the FRP thickness according to your strength requirements to achieve the best mechanical properties.

Core Material and Performance
FRP can be composites with many materials through adhesives. Commonly core materials include foam (XPS, PET, PVC, PU, etc.), honeycomb (polypropylene), plywood, etc. Using different core materials can bring different application effects to FRP sandwich panels, such as foam core has advantages in thermal insulation, honeycomb core is lighter, and plywood has higher strength. Or different materials can be combined together as core materials to make the panel gain multiple advantages.
