Smooth Cor is a CMP pipe with a hydraulically smooth steel liner coated with polymer coating. This combination makes Smooth Cor Pipe the economical and performance alternative to reinforced concrete pipe in difficult situations such as weak soils, poor subsurface drainage conditions, steep slopes, and high fills.

Smooth Cor™ consists of a standard corrugated steel pipe as its structural exterior shell and includes a hydraulically smooth steel liner. Both the interior liner and exterior shell are coated on both sides with a polymer coating. This combination makes Smooth Cor Pipe the economical and performance alternative to concrete in difficult situations such as weak soils, poor subsurface drainage conditions, steep slopes, and high fills.
Smooth Cor can be fabricated into any type of structure including tees, elbows, laterals, catch basins, manifolds and reducers. Pre-fabricated fittings are more economical and have superior hydraulic characteristics when compared to concrete structures.
Smooth Cor should be specified as an alternative under normal site conditions and specified exclusively under very difficult situations that demand the strength of CMP with positive joints and a hydraulically efficient smooth liner.
