The aluminum honeycomb core is composed by multilayer aluminum foil, honeycomb is formed after fully expanded. Our aluminum honeycomb core has sharp and clear hole surface, and it is suitable for adhering to high grade plate as well as other purposes. At present , two types of product we mainly produced are micro-aperture aluminum core and normal aluminum core.

It is a kind of high strength external building material, which was only applied in the aeronautic industry in the past. The surface layer of such panel is aluminum alloy sheet, while the central layer is the honeycomb structure made of aluminum foil. Aluminum Honeycomb Panel has excellent rigidity and is the best one of the metallic wall material available today. It has been widely used in the decoration of modern architecture , train, auto mobile and ship manufacturing industries.

PVF2(PVDF) color protection layer is fluorocarbon polymer, the base of which is KYNAR500 polyvinylidene resin fluoride invented by American Pennwalt Company. This kind of protection layer has superb performance in anti-efflorescent , long lasting and chemically resistance to corrosion. Therefore , it can be widely used in various climates and environments, from the chilly and dry Northern Europe to the torrid and humid tropical zones.





Light in weight, flat in smoothness , and strong in strength , Stone Honeycomb Panels process various advantages. Good performance in sound attenuation and heat insulation , as well as in anti-impact, fire-resistance , chemical corrosion , anti-ageing performance, it owns a unique competitive edge over other similar materials. Easy in installation , It is , nonetheless , more suitable for high-storey buildings as exterior wall panels or interior wall decoration.
