TUF GATE Aluminum Stop Gates

TUF GATE Aluminum Stop Gates are widely used in wastewater treatment plant design. Designed for flow control with minimal seepage. The gates consist of 1/4″ aluminum plates reinforced with aluminum structural shapes. The gates can be designed in-house for most any width and head.

The frames are aluminum extrusions, alloy 6063-T6 and incorporate a continuous concrete anchor. Embedded as well as face mounted frames are available. Anti-friction inserts are an option for each frame type. The inserts serve to reduce the required lifting capacity of the gates.

Features

  • 1/4″ aluminum plates and reinforcing of alloy 6061-T6
  • Extruded aluminum guides alloy 6063-T6
  • Lift handles
  • Portion of aluminum in contact with concrete is painted with bitumastic​
Options

  • Reinforced for most standard sizes
  • Design calculations
  • Anti-friction inserts of ultra-high molecular weight polyethylene (UHMWPE)

Specifications

1) Stop Gate Guides are to be extruded aluminum, alloy 6063-T6 or 6061-T6. If required, the stop gate frames shall incorporate an anti-friction UHMW insert to reduce the coefficient of friction to 0.2 or less.

2) Stop Gate Disc shall be a minimum of .25″ thick aluminum plate, alloy 6061-T6. The disc shall incorporate a lift handle for hand operation. The disc shall be stiffened as required to meet the loading requirements of the intended application with a minimum of deflection. Design calculations shall be furnished upon request.

3) Surfaces in contact with concrete shall be protected with a shop coat of bitumastic paint.

4) Aluminum Stop Gates shall be “TUF GATE“ as manufactured by Thompson Fabricating, LLC (B’ham., AL.) or approved equal.
