The most basic industry is the Iron and steel industry as all the industries are depended on this industry for their machinery. Iron and Steel is an important metal because it is used for manufacturing engineering goods, construction material, defence, medical, telephonic, scientific equipment, and a variety of consumer goods. India is considered as the largest exporter of steel, i.e, and 2.25% in 2004 in the global steel trade.
The north-eastern part of the Peninsular Plateau region has the maximum concentration of iron and steel industries because of the certain factors this place has which poses as the ideal location for the iron and steel industries. These factors are - low cost of iron ore, high-grade raw materials, cheap labour and growth of this industry in the home market.
Also, India is still not able to perform to its full potential due to high costs and limited availability of coking coal, lower productivity of labour and irregular supply of energy and poor infrastructure. But the availability of steel is enough to meet the domestic demand.
