Architectural stone, as we understand it, corresponds to rough or cut stone, shaped to be used in indoor or outdoor architectural projects.
Architectural stone includes dimension stone and rough stone. Dimension stone, which is worked and often polished, is used in sculpture and to produce cut-to-size panels, tiles, cut stone, curbstones, veneers, and monuments. Rough or roughly dressed stone is used to produce cobblestones, flagstones, and paving stones.
The rocks most commonly used are granite, limestone, marble, sandstone, and slate. The stone market is subject to technical and aesthetic standards, such as those related to porosity, hardness, or resistance. The sale of rough or processed stone is highly dependent on a competitive international market, governed by well-established distribution networks.
Dimension stone has specific form and dimensions. It is usually extracted from quarries as large blocks, which are sawn at a plant into cut-to size panels or tiles of different sizes and processed to produce various finishes.
Cut stone is shaped by hand or using a guillotine splitter. Rough blocks are processed into cut stone of various sizes. Cobblestone is small roughly dressed or undressed stone. Flagstones are large and thin.
