POLYCAST® 600 Series

THE 20% ADVANTAGE

48″ vs. Meter Channel Lengths

  • Fewer Channels

  • Fewer Joints

  • Fewer Issues

  • Less Labor

  • Faster Installation

Hubbell’s POLYCAST® 600 Series is one of the most prominent small commercial drains on the market. The 6.25″ wide (OD) polymer concrete channels have a built-in .65 percent slope that allows the system to achieve flow rates of 470 GPM, higher than drainage systems of similar size. Channels are offered in 48″ and 24″ lengths. Channel edge protectors are available in galvanized steel and stainless steel. Projects where deep sloping channels are required, POLYCAST® 600 Series also offers extender panels which increase the depth and length of a trench drain run.

POLYCAST® 600 Series installation chairs tighten the joints between channels while aligning and leveling the drainage run. Each installation chair is secured to the ground, ensuring that the channels will not float during the concrete pour.

POLYCAST® Grating

With the POLYCAST® Series commercial drainage system, you have a wide selection of grating options. The grates measure 5.25″ in width, com in either 24″ or 48″ lengths and are secured by a bolt and toggle system. Load capacity of the 600 Series grates range from pedestrian (Class A) to heavy automobile traffic (Class D). For heavier loads, POLYCAST® 700 Series is available. This system offers grating in a wide range of material types such as:

  • Fiberglass
  • Cast Iron
  • Ductile Iron
  • HDPE
  • Galvanized Steel
  • Stainless Steel

Grate styles are available in:

  • Slotted
  • Perforated
  • Bar
  • Solid
  • Transverse Slotted
  • Decorative Patterns

Ductile Iron grates are available in a raw state that naturally rusts or in a Baked on Oil Finish (BoOF) in which the natural oxidation process is sped up and finished with a clear powder coat that provides protection to the brown patina. Many of these grates meet bicycle safety, heel friendly and ADA requirements for wheelchairs.

Hold Down Devices

Locking devices vary based upon the grate material and POLYCAST series.

Bolt and Toggle Locking

Hold-down or locking devices serve several purposes. They help to keep grates securely placed within the trench drain system to prevent them from hopping as traffic crosses them. It also prevents debris such as stones from getting between the channel and the grates which could erode, pivot and break over time. They also serve to deter theft of the grates.

Standard POLYCAST® locking devices consist of a bolt that feeds through the grate into a bar inside the channel that lock into side pockets. Grates are made in a variety of materials and coordinating lock down devices are available for each type.

Vinyl Ester Option

Some trench drains may be exposed to constant high temperature and corrosive solutions, POLYCAST® recommends the 600 Series made with a vinyl ester-based polymer resin. POLYCAST® vinyl ester polymer concrete is a product of choice in breweries and chemical manufacturing facilities due to its temperature and corrosion resistant properties.  Vinyl ester polymer concrete is an economical alternate to a stainless steel body channel, as well.  When using stainless steel POLYGUARD edging with the POLYCAST® vinyl ester channel, you achieve the same clean look that you achieve with a stainless steel system, while satisfying engineering parameters of the drainage system.

POLYGUARD Edge Protectors

When selecting grate options, consider adding POLYGUARD edge protection to your channels. Edge protection installs easily over the top of the channel and covers the upper horizontal and vertical surfaces. Besides giving your channel a clean and sleek commercial look, POLYGUARD protects the exposed upper edge of the POLYCAST 600 series channels from unplanned impacts that lead to chipping and scarring. POLYGUARD is supplied in pairs of 24″ and 48″ lengths and are available in galvanized and stainless steel.

End Caps / Outlets

POLYCAST® systems have a few options for end caps  and outlets. Choose from the site sizeable DA0670 combination inlet/outlet cap are used to enclose or provide piping transitions to outlet or inlet ends of the channel whenever catch basins are not being used. End caps output to a 4″ pipe.

Polymer concrete end caps with outlets are also available for 6″ pipe. The end caps with 6″ outlets are made to fit the 620, 620H, 625, 625N and 625H channels.

The DP0600C series end caps are available exclusively from Trench Drain Systems. These end caps fit the shallow end (inlet side) of channels 600N to 615 and are made from either polyester or vinyl ester polymer concrete. Each end cap is identified with the corresponding channel number, fit the channel recess exactly, are secured with construction adhesive and have the same width as the channels edge. They simplify installation and provide a congruent look.

Another TDS exclusive is the DP0670F sold end outlet series. These outlets are used when bottom draining makes the end outlet option unnecessary. This is particularly important where high temperature solutions exceed the temperature limit of standard plastic end caps. End caps are available for all channels for all channels with bottom cut-out templates (600, 605, 610, 615, 620, and 625). Embossed cut-outs templates in most end caps facilitate field fabrication when appropriate.

Polymer concrete end caps with outlets are also available for 6″ pipe. The end caps with 6″ outlets are made to fit the 620, 620H, 625, 625N and 625H channels. Due to the pipe diameter of the 6″ pipe, only deeper POLYCAST® channels have this option.

Installation Chair

Installation chairs are the most efficient and economical means of setting a precast trench system.  The installation chair supports the ends of the channel, aligns and locks the joints rigidly together, and prevents the channels from floating.  Adjusting channel elevation is easy.  One chair is required for every joint.  Each chair is made from 1018 hot rolled steel and has a zinc plated finish.

POLYCAST® 600 series installation chairs tighten the joints between the channels while aligning and leveling the drainage run. Each installation chair is secured to the ground via rebar, ensuring that the channels will not float during the concrete pour.

Dimples near the ends of the channel allow the installation chairs to be locked into place.
