PolyDome Bulk Bins are the perfect choice for handling granular materials. They are made of high-density polyethylene which will never rust or corrode. PolyDome Bulk Bins will always remain clean and attractive.
The interior surface of PolyDome Bulk Bins is very smooth to reduce bridging. Plus, since they are just 2-piece construction there are no rivets and seams to contend with. The translucent polyethylene allows you to visually check material line from the outside.
All PolyDome Bulk Bins have a 22” top opening with a hinged, vented filler cap and a pull rope that allows ground
control for filling.
There are 3 different transition collars available for the slide valves– 90°, 45°, and 30° angles. The new style collar
