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® Bands. el, Aluminized Steel Type 2 and polymer-coated steel. Standard fittings include tees, wyes, elbows, saddle branches, reducers and manifolds for detention systems.
Efficiently Remove Surface Water on Streets and Parking Lots Slotted Drain pipe is a practical, aesthetically pleasing inlet for the efficient removal of surface water on streets and highways. It also is widely used in parking lots and similar locations to remove sheet flow without complex multiple grades or water channeling devices. Slotted Drain pipe is fabricated from CONTECH Corrugated Steel Pipe, which is cut along a longitudinal axis.
Steel-lined Corrugated Steel Pipe for Superior Hydraulics Smooth Cor is a smooth interior pipe that consists of a standard corrugated steel pipe as its structural exterior shell and includes a hydraulically smooth steel liner that is continuously attached to the exterior shell along the lock seam. Both the interior liner and exterior shell are coated on both sides with TRENCHCOAT® polymer coating by Dow Chemical Company.
Structural Strength with Superior Hydraulics With over 20 years of proven performance, 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 including elbows, manholes and catch basins. Available in galvanized steel, Aluminized Steel Type 2, polymer coated and aluminum to meet a wide variety of environmental and service life requirements.
