There are round plastic ducts and flat plastic ducts, both are made of polyethylene or polypropylene. The plastic duct is mainly used for prestressed tendons hole-making in post tensioning concrete structures. It is connected with different specifications of plastic duct connectors in actual application.
Feature:
● High corrosion resistance, aging resistance and fatigue durability
● Excellent sealing and impervious performance
