The SS600 Series stainless steel trench drain is designed for commercial markets. Exclusively by TDS, this system features a built-in 1% percent slope and a smooth v-shaped profile, allowing the system to achieve flow rates up to 470 GPM. The channels measure 48″ long, 6.25″ wide (OD) with a 4″ wide throat (ID). The 16 gauge 304 stainless steel channels are chemically inert and resistant to high temperatures. The flanged channels join with the provided bolts and rubber gasket for a secure fit. The lightweight channels minimize installation time.

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.
