Cement

The iron and steel industry is the basic industry because all other industries (heavy, medium and light) are dependent on the iron and steel industry for machinery. Steel is needed for the manufacture of various engineering products, construction materials, defence, medical, telephone, scientific equipment and various consumer goods. Steel production and consumption is often considered as an index of a country’s development. Iron and steel is a heavy industry because all raw materials and final products are heavy and bulky, which requires heavy transport costs.
