Corrugated Metal Pipe
Customer Proven Innovation
Contech® provides a full range of Corrugated Metal Pipe for
severe-to-normal conditions
Coast-to-coast, engineers and contractors rely
on Contech Corrugated Metal Pipe for culverts,
storm sewers, small bridges, stormwater detention
systems, conduits and windmill foundations.
No other type of drainage structure offers the
range of structural strength that’s available with
Corrugated Metal Pipe—it performs where rigid
pipe fails.
Contech Engineered Solutions LLC
manufactures to repeatable and exacting
standards HEL-COR
pipe—which has a 0.012 Manning’s “n”—in
galvanized, Aluminized Steel Type 2, polymer
coated and aluminum.
Numerous industry standards for pipe
configurations, coatings and linings have been
conceived and developed by Contech. That is how
we have earned the reputation as the world leader
in pipe design and innovation.

Corrugated Steel Pipe …
The Core of Strength
Corrugated steel pipe is similar to the superstructure
of a building in that it supports the interior walls and
gives structure to the facade. Steel is the proven, strongshouldered material that is coated with zinc, Aluminized
Steel Type 2, tough polymer or asphalt to increase durability
for prolonged design life. Corrugated steel pipe is the
strength at the core of all coatings and linings.
Contech’s Corrugated Steel Pipe provides the power and tenacity
to your culverts, storm sewers and stormwater detention systems
to withstand severe environmental conditions and burial depths.
We offer coatings and linings to increase the life of installations
up to 100 years as well as provide products with a Manning’s
“n” equivalent to other smooth wall drainage products.
Two primary shapes
Full-round pipe is recommended for most applications.
However, for limited headroom conditions, Contech
produces a pipe-arch shape. The low, wide pipe-arch
design distributes the area horizontally to provide adequate
capacity without raising the grade.
Corrugations and wall thicknesses
Both Contech Pipe and Pipe-Arch are produced in six wall
thicknesses including 18, 16, 14, 12, 10 and 8 gage, which
are available with either helical or annular corrugations.
Contech HEL-COR
with continuous locked seams, and with rerolled annular
ends. Contech riveted pipe is furnished with annular
corrugations only.
Corrugations include 1economical and efficient metal use in small diameters;
3” x 1” and 5” x 1” offer high sectional properties in largediameter pipe.
The wide variety of corrugations and thicknesses permits
selection of materials for a balanced design to meet specific
jobsite conditions. Each project can be designed individually
for the most cost-effective combination of corrugations,
thicknesses, sizes, materials and installations, maximizing
your investment on a job-by-job basis. For guidance, call
your local Contech sales representative.

HEL-COR® Corrugated
Steel Pipe
Helically corrugated HEL-COR steel pipe, available in round
and pipe-arch shapes, has over 55 years of proven
performance. It is manufactured with continuous
locked seams with annular corrugated ends to use
with soil-tight HUGGER
Typical applications are culverts, stormwater
detention systems, small bridges, conduits and
storm sewers. A wide variety of wall thicknesses
(gages), corrugations, diameters and pipe section
lengths permit a choice of materials to meet
specic job site requirements.
Durability requirements are addressed by a wide choice
of materials: Galvanized Steel, Aluminized Steel Type 2
and polymer-coated steel. For increased hydraulic efciency,

CORLIX® Aluminum Pipe
Long Service Life … Economical
Contech’s CORLIX Aluminum Pipe provides a
predictable service life of more than 75 years
when installed in the recommended soil/water
environment. It is ideal for municipal storm
sewers, underground stormwater detention
systems or any standard drainage project that
must withstand corrosive environments.
Economical
Lower initial cost begins with CORLIX pipe’s weight.
It weighs only 1/35 as much as reinforced concrete.
Lighter weight means easier installation. Trench width
and depths are reduced due to the smaller outside
diameters, resulting in time and cost savings for both
excavation and backll.
Single lengths up to 40 feet ensure more accurate
pipe alignment at time of placement and through the
life of the system. Longer lengths save installation time
with fewer joints. Even more footage per truckload is
possible with bundles of nested pipe—and unloading
time is minimal.
A CORLIX underground detention system with prefabricated stubs
eliminates the need for forming concrete junction boxes.
Predictable service life of more
than 75 years
CORLIX Aluminum Pipe can be installed in salt water
environments.

ULTRA FLO
smooth interior corrugated
storm sewer pipe
Manning’s “n” of 0.012 … Equal to Concrete Pipe
ULTRA FLO has over 25 years of proven performance
on municipal, transportation, residential development,
shopping center and airport storm sewer and stormwater
detention projects. ULTRA FLO’s rapid acceptance is based
on its Manning’s “n” of 0.012, structural strength and
faster/lower-cost installation than concrete. Plus, ULTRA
FLO is available in galvanized steel, Aluminized Steel Type
2, polymer coated and aluminum to meet a wide variety of
environmental and service life requirements. For projects
with limited headroom, ULTRA FLO is available
in pipe-arch.
—
Millions of feet of ULTRA FLO have been installed in
thousands of storm sewer projects nationwide, providing
significant cost savings. Because steel ULTRA
FLO weighs less than 10% of concrete pipe,
handling and installation costs are greatly
reduced. Aluminum ULTRA FLO has only
1
/35 the weight of concrete pipe. Lower
labor costs also result from fast and easy

coupling bands do
not require special
skills or tools. Twenty-
foot standard
lengths mean fewer joints
and faster laying. And, longer
lengths are available on special order.
ULTRA FLO’s smaller outside diameter
permits a reduction in trench widths
and depths, providing time and cost
savings for both excavation and
backfilling operations.

Superior Hydraulics
Research at Utah State University shows that
ULTRA FLO Storm Sewer Pipe Systems are
hydraulically equivalent to reinforced concrete pipe.
The Water Research Laboratory performed hydraulic
tests on ULTRA FLO spiral-rib pipe with
3
/4” x 3/4” x 7 1/2” continuous ribs. At full flow, the Manning’s
“n” was 0.012 (Report No. 1277 and 1278, 2002). For
further reference, see FHWA Hydraulic Design
Series No. 5, December 1996.
ULTRA FLO is one of the most hydraulically efficient storm
sewer systems available because of its smooth interior
surface and longer lengths, resulting in fewer joints and
hydraulically efficient prefabricated junctions: elbows,
manholes and catch basins.
Smooth interior of ULTRA FLO pipe improves
hydraulic capacity while the exterior box ribs
provide structural strength.
