Side-slot Drain Pipe Helps Remove Road Surface Runoff

We all have similar experiences. After rain, we see much road runoff can not be drained by faraway catch basins immediately and effectively, to make it worse, some of them will stay there for a long time, waiting for evaporation. Evidently, this is a problem, sometimes even a danger.

Thanks to the engineers, Anrun Factory developed a continuous drain pipe called Side-slot Drain Pipe, or call it Road Side Drain Pipe as you like. We produce this pipe based on normal corrugated steel culvert pipe, by welding a rectangular grating steel slot on one side of the metal culvert pipe. After installed along & beneath the road, the continuous gutter are created for draining surface runoff effectively and clearly.

As a factory devoted to providing our customers optimal anti-corrosion pipe solutions, we accept customization on pipe diameter and wall thickness, either galvanized or polymer coated steel is OK.
