The solution for outdoor and indoor signage of locations (shopping centers, company headquarters, etc.), volumetric letters made by computerized cut, give increased visibility and a high-class style, through their three-dimensional effect. Also this “signaling” mode comes as a perfect solution for buildings located in protected areas, architectural monuments or buildings with special architecture. The material used to make them is extruded polystyrene, with a fine structure. Volumetric signs in polystyrene can be painted in a wide range of colors, so their degree of use is practically unlimited.
