POLYCAST® polymer or Vinyl Ester concrete systems with stainless steel edging and grates are a good alternative to stainless steel channel bodies. Polymer channels are chemically inert and resistant to high temperatures. This series is perfect for breweries and other industries that experience extreme conditions.
Hubbell’s Polycast 700 Series is the logical trench drain choice for heavy duty applications with constant fork trucks or heavy equipment. The Polycast 700 features 6.25″ wide (OD) polymer concrete channels with a 0.6% built-in slope that offers flow rates of 470 GPM. Polycast 700 is based on the 600 series channel, and so shares many of the features that make Polycast 600 a prominent small commercial drain.
The Polycast 700 framing technology sets the heavy duty system apart from other polymer concrete drains. Cast iron or high density polyethylene frames significantly increase the system’s load bearing capabilities by transferring pressure into the surrounding concrete. The 700 Series framing system also protects the underlying polymer concrete channel from weathering and freeze-thaw deterioration.
When added to the 600 series channel, each 700 Series frame adds 1.19″ of additional depth to the channel invert. Polycast 700aa and 700pe frames are designed to allow the same 600 series grates to be used in the 700 Series frames.
