Why TrueNorth Steel

Multiple End Treatment Options

Bevel Cut End

Bevel Cuts

Bevel cuts can be done in several fashions. Step bevels are recommended for all pipe sizes. Step bevels are typically limited to 3:1, 2:1, or steeper slopes on long span and larger structural plate pipe, depending on their rise. Full and partial bevels are typically applicable only to smaller pipe. The NCSPA Design Manual is your guide to the best option on a bevel cut for your project. We also have standard detail drawings on optional bevel cuts for your reference.

Flared End Section

Headwalls

Prefabricated steel headwalls are designed to accommodate pipe diameters from 12” to 144”, skewed end pipes and pipe arches. Wingwalls, if required, can be designed and provided as well. Headwalls are pre-attached to the end of the pipe and pre-assembled at the factory to assure proper fit and finish.

Flared End Section

Standard Flared End Sections

Standard flared end sections are not only long-lasting and easy to maintain, they are up to standards and easy to install. Matching the fill slopes, the end section “finishes” the appearance of the culvert and keeps grass, weeds and debris from the culvert opening. It also increases flow characteristics, preventing scouring and undercutting. Available in sizes 6” to 96” round, as well as arched sizes 17”x13” to 112”x75” with a standard 2:1 slope. The NCSPA Design Manual is a great source for what end finish is best for your job.

Safety Slope End Section

Safety Slope End Sections

Safety slope end sections have contributed greatly to improved highway safety for motorists, while increasing the hydraulic capacity of the culvert with their smooth, long, and narrow design. They are available in 4:1 and 6:1 slopes and feature optional traversable parallel or cross-drain bars. All hardware is included to attach the safety slope end section to your corrugated steel pipe. The NCSPA Design Manual is a great source for what end finish is best for your job.

Safety Apron End Section

Safety Apron End Sections

Safety apron end sections have also contributed greatly to improved highway safety for motorists, while increasing the hydraulic capacity of the culvert. Their cutback designs are corrugated, long and narrow attached with a band. They are available in 4:1, 6:1, and 10:1 slopes and feature optional parallel grates. The NCSPA Design Manual is a great source for what end finish is best for your job.

Rodent Guard

Rodent Guards

Steel Rodent Guards are easy to install and prevent rodents and other pests from plugging your drainage systems. These guards position far enough in the pipe that it can swivel up and allow trash to pass without exposing the Rodent Guard beyond the pipe. Depending on the diameter needed, the structural design may vary but all have the same end goal.

Trash Guard

Standard Flared End Sections

Steel Trash Guards, also known as Child Protection Grates, are designed to fit onto a standard flared end section. They are used to prevent unwanted material from entering the pipe which may result in clogging.
