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.

SS600 Engineering Specifications

Specification Sheet for DG0670 Grate



  • HDPE plastic slotted grates – black
  • Class A Load Rating

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.
