GI (Galvanized Iron) pipes are another important class of pipes used in a variety of applications as well as industries. Galvanization is a process in which iron or steel is coated with a layer of zinc to protect them from corrosion or rusting. Pure iron is very ductile and contains no carbon. The metal zinc lasts long and helps to increase the life of iron or steel. Galvanized Iron pipes and steel are used in most of the structural applications and come with a layer of zinc to give 100% protection from rusting. These pipes and tubes come in numerous sizes and shapes according to the specific requirements of the customers.
