Our products



The GammaStone AIR system allows designers to confidently choose large format lightweight panels. The panels are mechanically anchored with hidden or visible fixings.



The main feature of the GammaStone AIR system is the high level of workability and flexibility of use; the panels can be cut at different angles, glued with structural epoxy adhesives and reinforced with metal corners forming a single monolithic architectural element capable of satisfying the most varied aesthetic and functional needs of buildings. These unique panels allow us to produce false beams or columns with complex and even irregular shapes or revitalize existing buildings with a new aesthetic.



KingStone has been operating in the field of extraction, processing and sale of natural stones for four generations, a culture since 1870 handed down by tradition of expert stonemasons and quarrymen. Over the years, the family has been involved in the cultivation and recovery of various marble and travertine quarries, in Italy and abroad.



An extremely versatile material, which allows great freedom in architectural design. Panels of various shapes and sizes can be made without limits. Designed to provide a new look to both old and new buildings. The UHPC allows you to change skin with multiple completely customizable solutions, both in colors and finishes.
