High Performance Outdoor Limestone - Portugal Beige Limestone – Union

Portuguese beige is an imported limestone with a beige color. Unlike granite, limestone is a kind of sedimentary rock from a geological point of view. It originates from fragments and debris of other rocks. These fragments are compressed and cemented by various natural environmental factors to form sedimentary rocks. In Europe and North America, the unique external effects of limestone are favored by architects and are used in exterior engineering. The main component of limestone is calcium carbonate (CaCO3), calcium magnesium carbonate or a mixture of calcium carbonate and magnesium carbonate. Limestone has many distinct natural features, such as: calcite’s lines or spots, fossil or shell structure, potholes, slender tissue, open texture, honeycomb structure, iron spots, travertine-like structures, and crystallographic differences. It is these characteristics that make limestone have natural senses and rich layers.
