Concept:The iron and steel industry is a heavy industry that is mainly located near its major raw materials.
Explanation:Iron and steel production requires bulky and heavy inputs such as iron ore, coking coal, and limestone.
Transporting these materials over long distances is very expensive.
Locating the industry near the sources of raw materials reduces transport costs.
It makes production cheaper and more efficient.

Thus, easy access to raw materials is the main reason for the location of the iron and steel industry.
