Profile: GCI Exports Private Limited specializes in manufacturing & exporting box culverts, industrial header rings and concrete pipe machinery. We are an ISO 9001 certified company. We also offer industrial joint rings and concrete pipe forms. Concrete boxes find application in several different areas such as culverts, retention tanks, vertical vaults, utility corridors and storm water drains, industrial waste and sanitary sewerage units. In addition they can also be used for underground walkways, transportation of goods and services. Culverts can be either wet casted or made using dry concrete and vibrated into place. They are made with a tongue % groove and are joined together either with a gasket or a sealing compound to make a leak proof joint. Forms are modular in construction and can expand from 1 mt x 1 mt to 6 mt x 6 mt. The design also allows for variation in each wall. Pallets rings & joint rings are dies used to form the female end of a concrete pipe. When used with a gasket it ensures that the assembly is a leak proof joint. Our rings are generally made from cast iron, ductile or SG iron and steel. They can be manufactured in different shapes like round, elliptical, arch and egg shaped.
