Corrugated Galvanized Iron (G.I) ducts are the most economical means to create a void for the tensile elements. These thin-walled corrugated sheet galvanized ducts also provide a secondary corrosion protection with excellent bond behavior between tendon grout and concrete. Primary corrosion protection is provided by the alkalinity of the grout and concrete. SPECIAL FEATURES
