Industrial Fabrics offers corrugated steel pip with environmentally resistant coatings and linings to prolong the life of installations up to 100 years.
Applications
Coast-to-coast, engineers and contractors rely on Corrugated Steel Pipe for culverts, small bridges, conduits, storm and sanitary sewers. No other type of drainage structure offers the range of structural strength that's available with corrugated steel pipe-it performs where rigid pipe fails.
Corrugated steel pipe transfers live and dead loads to the surrounding soil envelope, creating a composite steel/soil interaction. Loads are distributed uniformly around the entire circumference of the round pipe-the unit pressure at the top and bottom being as little as one-third of that on a rigid pipe under identical loading conditions. This composite action provides an economically, structurally sound approach to pipe design.
Two primary shapes
Full-round pipe is recommended for most applications. However, for limited headroom conditions, Industrial Fabrics offers a pipe-arch shape. The low, wide pipe-arch design distributes the flow area horizontally to provide adequate hydraulic capacity without lowering the grade.
Corrugations and wall thicknesses
Both Pipe and Pipe-Arch are produced in six wall thickness from 0.052 to 0.168-inch and are available with either helical or annular corrugations. HEL-COR® Pipe (helical corrugations) is furnished with continuous buttwelded or locked seams, and with rerolled annular ends. Riveted pipe is furnished with annular corrugations only.
Corrugations include 1-1/2" x 1/4" and 2-2/3" x 1/2" for economical and efficient metal use in small diameters; 3" x 1" and 5" x 1" offer high sectional properties in large diameter pipe.
The wide variety of corrugations and thicknesses permits selection of materials for a balanced design to meet specific job site conditions. Each project can be designed individually for the most cost-efficient combination of corrugations, thicknesses, sizes, materials and installations, maximizing your investment on a job-by-job basis.

Diameters and Lengths
Corrugated Steel Pipe is available in diameters ranging from 12" to 84" in the 2-2/3" x 1/2" corrugation. Smaller diameters (6", 8" and 10") are available in 1-1/2" x 1/4" corrugation, but only in lock-seam construction.
Pipe-arch sizes range from 17" x 13" through 83" x 57" for 2-2/3" x 1/2" corrugations and up to 142" x 91" for both 3" x 1" and 5" x 1" corrugations. Normally pipe and pipe-arch are supplied in 20-foot lengths. Other lengths are available on request.
Materials
Pipe and pipe-arch are fabricated from four materials. Galvanized steel is used for normal applications. TRENCHCOAT® (polymer pre-coated steel), ALUMINIZED STEEL Type 2™ and FIBER-BONDED steel are used for increased durability.
