The slotted drain is a surface water collection system that effectively removes runoff from flat, paved surfaces to promote safety and convenience. We offer three grate options in variable grid heights and widths – welded single and double width grates, and welded or removable triple width grates. The slotted drain is made of durable galvanized steel and can be connected to CSP, PVC or HDPE pipe.

Slotted drains resist freeze/thaw cycles and their easy maintenance make it perfect for installations with no slope, steep slope or pipes with shallow burial. This drainage product is perfect for highway medians, airport, parking lots, sport stadiums, or where curbs are undesirable. Slotted Drain is approved by most provincial Transportation Departments and Ministries across Canada, as it provides an aesthetic and efficient option for storm drainage.
