Kataria Single Wall Corrugated (SWC) Spiral pipes are extensively used as duct for
bonded post tensioning tendons in prestressed concrete. Kataria SWC pipes resolve
the issues of corrosion which is a great threat to the reinforced concrete structure.
Kataria SWC pipes can be manufactured as per National, International or customers’
specific technical specifications.
