Tailored Composite Panel Solutions for Every Application

TOPOLO has developed a series of high-performance composite panels using polypropylene honeycomb, closed-cell foam, and waterproof plywood as core materials. Depending on different application requirements, these cores can be combined with various surface skins such as FRP (GRP), aluminum, steel, PVC, PET, etc.
These panels can be custom-designed in terms of structural configuration, thermal performance, and protective properties, meeting users’ demands for thermal insulation, lightweight strength, waterproofing, moisture resistance, corrosion resistance, and weather durability.
