CORRUGATED STEEL PIPE

Technical Specification Guide

TrueNorth Steel® manufactures and supplies a wide range of drainage pipe materials to service virtually any application. We have extensive experience and expertise in assisting engineers, project owners, and contractors with the design and installation of these systems and the selection and specification of the proper materials to meet the project requirements.

We manufacture and supply corrugated steel pipe from 6” diameter through 144” in round and pipe arch shapes using galvanized steel, aluminized steel, and polymer coated galvanized steel. (192” diameter corrugated steel pipe is available from some locations. Please inquire.) We also manufacture Spiral Ribbed corrugated steel pipe featuring a Manning’s “n” of .012 which is widely utilized for storm drains where a smooth interior pipe is a necessity. Slotted drain for curb drains and sheet flow drainage is available in a wide range of configurations. If it conveys water, TrueNorth Steel has the expertise.

Our manufacturing facilities and stocking locations can manufacture a full range of wyes, tees, elbows, risers, and manholes. Additionally, TrueNorth Steel specializes in prefabricated headwall assemblies for corrugated steel pipe which dramatically speeds up construction, reduces cost and protects culverts from erosion and scour forces. For those projects requiring larger pipe sizes or specialized shapes such as box culverts, refer to our TruePlate® Structural Plate guideline.

It is our mission to service our customers in a timely manner with high quality materials from all of our sites. We stock a wide range of sizes, corrugations, coatings and lengths and we pride ourselves in being able to react quickly to emergencies and other unplanned needs. Our own logistics group delivers corrugated steel pipe to your location utilizing our fleet of trucks and trailers.

Our local representatives are very experienced and are available to provide pricing and availability, technical support and field-installation support. We also supply our materials through an extensive network of distributor partners in WI, MN, SD, NE, CO, ND, WY, ID and MT.
