POLYCAST® 600 Series is a polymer concrete channel that has a built-in 0.65 percent 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.

Load class ratings for entire systems will always be determined by the lowest class within the system. For example, if the channel is rated as a C and the grate is rated as a D, the overall system will be rated as load class C. The same is true should the channel be rated as load class C and the grates are rated as load class A; the system as a whole would be rated as load class A.
