Structurally Sound
Slotted Drain is an efficient, cost-effective solution to surface water removal. The drain collects runoff and then distributes it to the pipe below, which flows to the proper outlet. Slotted Drain is assembled by welding a narrow section of grating in the top of a Corrugated Metal Pipe.

Efficient Drainage
The Slotted Drain is efficient for taking care of sheet flow on streets, highways, parking lots, shoulder medians, airport runways, and more. This versatile drain has also been proven effective in curb inlets. Slotted Drain resists warping under heavy traffic and thermal expansion. When winter rolls around, the drain is just as efficient in handling snow as it is with rain.

Metal Culverts, Inc., offers the parallel side grate design Slotted Drain. It is available in standard 2 1/2" and 6" heights, as well as a variable height. This hydraulically efficient and easily maintained product is available with a continuous drain guide and a wire mesh heel guard.
