End Sections

ENGINEERED SOLUTIONS

Standard End Sections for
corrugated metal pipe, reinforced
concrete pipe and HDPE Pipe

Easily installed, easily maintained culvert end
treatments

Contech
hydraulically superior method of finishing a variety of culvert
materials.

The lightweight, flexible metal construction of Contech End
Sections creates an attractive, durable and erosion-preventing
treatment for all sizes of culvert inlets and outlets. They can
be used with corrugated metal pipe having either annular or
helical corrugations, and both reinforced concrete and plastic
pipes. End sections can be salvaged when lengthening or
relocating the culvert.

Standard End Sections are fabricated from pregalvanized steel.
For added corrosion resistance, aluminum End Sections are
available in smaller sizes. Special End Sections for multiple pipe
installations may be available on a specific inquiry basis.

Better hydraulics

Flow characteristics are greatly improved by the exacting design
of Contech End Sections. Scour and sedimentation conditions
are improved, and headwater depth can be better controlled.
Culverts aligned with the stream flow and finished with Contech
End Sections generally require no additional hydraulic controls.

Improved appearance

Contech End Sections blend well with the surroundings. The
tapered sides of an End Section merge with slope design to
improve roadside appearance. Unsightly weeds and debris
collection at the culvert end are reduced.

Economical installation

Lightweight equipment and simple crew instructions result
in smooth and easy installation. Contech End Sections are
easily joined to culvert barrels, forming a continuous, one­piece structure. For easiest installation, End Sections should
be installed at the same time as the culvert. Installation is
completed by tamping soil around the End Section.

Low maintenance

Contech End Sections reduce maintenance expense because
their tapered design promotes easier mowing
and snow removal. There is no obstruction to hamper
weed cutting.

Notes for all End Section:

1. All three-piece bodies to have 12-gage sides and 10-gage center panels.
Multiple panel bodies to have lap seams which are to be tightly joined by
galvanized rivets or bolts.

2. For 60” through 84” sizes, reinforced edges are supplemented with stiffener
angles. The angles are attached by galvanized nuts and bolts. For the 66” and
72” equivalent round pipe-arch sizes, reinforced edges are supplemented by
angles. The angles are attached by galvanized nuts and bolts.

3. Angle reinforcements are placed under the center panel seams on the 66” and
72” equivalent round pipe-arch sizes.

4. Toe plate is available as an accessory, when specified on the order, and will be
same gage as the End Section.

5. Stiffener angles, angle reinforcement, and toe plates are the same base metal
as end section body.

6. End sections with 6:1 and 4:1 slopes are available in 12” through 24”
diameters.

7. Actual dimensions may vary slightly.
