Marble Balustrades

U.S. building codes mandate that balusters have no more than a 4 inch (10.16 cm) gap between them.

A balustrade can be made from virtually any stone material, which can be carved: Granite, Marble, Limestone, Travertine, Onyx, Sandstone, Limestone, Tuff Stone, Andesite and more.
