POLYCAST 600 Series is a polymer concrete channel that has a built-in 0.65% slope that allows the system to achieve flow rates of 470 GPM. The installation chairs tighten the joints between channels while aligning and leveling the drainage run. Each installation chair is secured to the ground (using your own rebar), ensuring that the channels will not float during the concrete pour. The grates are made of fiberglass and are normally used in areas where extreme chemical resistance is needed but with no heavy loads. The separation between bars is 0.38″. Gritted top non-slip surface.
