TUF GATE Aluminum Stop Gates

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