Information @ a Glance


  • Granite  is a common and widely occurring type of intrusive, felsic, igneous rock. Granites are usually medium to coarsely crystalline, occasionally with some individual crystals larger than the groundmass forming a rock known as porphyry. Granites can be pink to dark gray or even black, depending on their chemistry and mineralogy. Outcrops of granite tend to form tors, and rounded massifs. Granites sometimes occur in circular depressions surrounded by a range of hills, formed by the metamorphic aureole or hornfels.
  • Granite is an igneous rock and is formed from magma. Granite magma has many potential origins but it must intrude other rocks. Most granite intrusions are emplaced at depth within the crust, usually greater than 1.5 km and up to 50 km depth within thick continental crust. The origin of granite is contentious and has led to varied schemes of classification.


  • There are, four operations that are involved in the processing of granite. They are: Dressing , Cutting/Sawing , Surface Grinding and Polishing , Edge-Cutting-Trimming.
  • Granite can be a given a variety of finishes by honing and polishing, bush hammering or flaming, each producing differing textures and colour effects. Honing and polishing is achieved by using a series of abrasive grinding discs graded from coarse to fine. Various types of machines are used, the older types in which the discs are changed or the stone moved manually from one to the next, and the newer ones in which the stone is automatically moved from one set of discs to the next.


  • Finland is one of the major exporters of granite and a world-leader in soapstone production. The annual turnover of the industry is approx. 200 million Euro, divided equally between soapstone and granite products. The value of export is approx. 40% of the turnover. Approx. 200 actively operating companies are found in the line of natural stone business in Finland, employing approx. 2000 persons (with spin-off approx. 3000 persons).
  • India is one of the leading countries in the production and export of granite and other stones. India's share of export of processed granite products (value added) has increased from 10% in the year 1985-86 to 70% in the year 1999-2000, as against granite dimensional blocks. Granite industry in India has been quite successful in exports.


  • The typical Applications Granite is used as a building stone, architectural aggregate, track & trail pathways, decorative landscape stone, decorative rip rap stone, and a source of economically valuable minerals. Granite Floorings , Granite Furniture , Granite Counter Tops , Granite Monument , Granite Table Tops , Granite Steps.
  • Granite aggregate is mainly used for road construction and maintenance, however there are many other uses which include concrete, landscaping stone and paving. Granite is a very durable stone and is used in a variety of ways. Its attractive appearance makes it useful as an architectural stone
