Slotted Drain is fabricated from galvanized steel for excellent durability or from Aluminized Steel Type 2 (ALT2) when more corrosion resistance is required. The slot collects runoff and channels it to the pipe below from which it flows to the appropriate outlet. The pipe is cut along a longitudinal axis, and a trapezoidal or straight-sided grate with reinforcing spacer plates is welded to form a 1 3/4 -inch-wide slot opening. These products, manufactured in accordance with AASHTO M252, AASHTO M294 or ASTM F2306, complies with the requirements in the Build America, Buy America (BABA) Act.Slotted Drain™ is a unique pipe which removes sheet flow without multiple grades or water channeling devices.
