Corrugated Steel Pipe & Pipe Arches

Lane fabricates and stocks a full range of corrugated steel pipe in a variety of materials, linings and coatings to meet specific durability and hydraulic requirements. Corrugated Steel Pipe (CSP) is available in round sizes from 6” through 144” and in pipe-arches through 120” equivalent. CSP is unparalleled in its ability to be fabricated to meet demanding site requirements, especially in larger diameters.

Material Options for Corrugated Steel Pipe and Pipe Arches:

Aluminized Steel Type 2 (minimum service life of 75 -100 years)
Aluminized steel pipe combines the strength of steel with the corrosion resistance of aluminum. Pipe is produced from steel coil with a one-ounce per square foot aluminum coating.


Asphalt-Coated Galvanized Steel
A uniform coating is applied to the interior and exterior of the pipe to increase the service life of galvanized CSP.

Galvanized Steel (minimum service life of 50 years)
The traditional galvanized CSP is produced from steel coil with a two-ounces per square foot zinc coating.


Polymer Coated Steel (minimum service life of more than 100 years)
A 10-mil polymer film is laminated over each side of a galvanized steel coil to create the premier coating available today. The protective film is a tough, rugged polyolefin laminate that provides galvanized CSP with a durable barrier that exceeds the corrosion and abrasion resistance of all other coatings with the added feature of providing a 100-year service life.


Benefits of CSP Include:

  • Long service life — 100+ years
  • The most environmentally-friendly and LEED-friendly drainage product on the market
  • Superior strength
