IMRI supplies both heavy rail and light rail.Crane rail is a kind of heavy rail, its height is lower, the head width and the waist thickness size is larger.It is used for laying crane track and trolley track. The steel rails we supply are widely used in railway engineering, vehicles, bridges, mechanical engineering, infrastructure construction and so on.
