ULTRA FLO® Corrugated Metal Pipe (CMP)
ULTRA FLO is a spiral rib pipe with a smooth interior that is the industry alternative to reinforced concrete pipe. The smooth interior improves hydraulic capacity while the exterior box ribs provide structural strength. ULTRA FLO weighs less than 10% of reinforced concrete pipe and comes in longer lengths, greatly reducing handling and installation costs.
Lower Cost Alternative to RCP Storm Sewer PipeULTRA FLO®, a pipe with a smooth interior, is the material of choice for storm sewer applications and a lower cost alternative to reinforced concrete pipe. The smooth interior improves hydraulic capacity (Manning’s “n” = 0.012, equal to concrete pipe) while the exterior box ribs provide structural strength.
ULTRA FLO is available manufactured with a variety of coatings such as, aluminized, polymer-coated, and aluminum material to meet a wide variety of environmental and service life requirements. For projects with limited headroom, ULTRA FLO is available in pipe-arch.
Because 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 joining. Contech Quick Stab® joints or coupling bands do not require special skills or tools. Twenty-foot standard lengths mean fewer joints and faster laying.
Shop-fabricated fittings save installation time in the field while providing hydraulically efficient junctions.

ULTRA FLO Pipe Coatings - Galvanized Steel - Pipe made from steel coated with zinc to extend service life. The most widely used and most economical metallic coating for corrugated steel pipe.
- Aluminized Steel Type 2 - Pipe made from steel that has been hot-dipped in commercially pure aluminum; offers 75 years or more of maintenance free service life.
- Aluminum Alloy - Pipe made with CORLIX® aluminum provides a predictable service life of more than 75 years; ideal for municipal storm sewers, underground stormwater detention systems or any standard drainage project that must withstand corrosive environments.
- Polymer Coating - Steel pipe with a heavy-gage polymer coating; protects against abrasion and corrosion to provide a service life of 100+.
ULTRA FLO Pipe Properties - Diameters 18”-120”
- Wall thicknesses of 16, 14, 12, and 10 gage
- 3/4” x 3/4” x 7-1/2” continuous rib corrugation
- Standards lengths are 20’-40’
ULTRA FLO Pipe Shapes - Full Round - recommended for most applications
- Pipe-Arch - used in limited headroom conditions. The low, wide pipe-arch design distributes the flow area horizontally, providing hydraulic capacity without lowering the grade.
