Introduction: The corrugated duct product is mainly be used for post-tensioned pre-stressed concrete structures as a pass-way pipe of PC strand tendons. In usually, it includes Metal and Plastic (HDPE) duct two types, which distinguish by their raw materials. The metal duct includes two types of galvanized steel and non-galvanized black steel. Each type duct includes two types of Round and Flat by the section shape.
Application: corrugated pipe is mainly used in highway, railway, municipal bridge engineering, elevated bridge, water conservancy project, large iron and steel plant construction (pre buried bolt Engineering) and large-scale high-rise building engineering pre-stressed corrugated pipe system products, grouting construction.
