GammaStone manufactures panels devoted to external and interior cladding systems for hotels, train stations, shopping malls, museums, manors, and hospitals. Our flagship product is Gammastone AIR: an innovative large size slab in natural stone, porcelain gres or glass. These patented panels are composed of a very thin porcelain gres or natural stone slab, a structural expanded core in between of two fiber glass mattings and a stainless steel plate of 0,5 mm thickness. The single components are compacted with resins at elevated pressure. Gammastone AIR panels are extremely lightweight and guarantee optimal resistance to impact, bending, compression, frost and temperature leaps.
