Grain Bins from Barn World

Barn World now carries a large selection of Poly Grain Bins.

Poly Grain Bins are a fantastic feed bin design and are perfect for handling high moisture soybeans, corn, and granular materials. These feed bins are polyethylene bins constructed with high-density polyethylene so they won’t corrode or rust. and will always be attractive and clean. 

Grain Bin Description

The interior surface is a very smooth two-piece construction that reduces bridging. There are no rivets and grain-clogging seams to contend with. The translucent polyethylene allows you to visually check the material line from the outside.

All of our plastic grain bins have a 22″ top opening with a hinged, vented filler cap and a pull rope that allows ground control for filling.

Feed Bin Collars

There are three different transition collars available for the slide valves– 90°, 45°, and 30° angles. (See Accessories on page 18.) The new style collar allows easier attachment to the bottom cone with little or no cutting necessary. Our slides feature a galvanized plate and guide system. Our auger boots will attach to any of our slide valves and handle 4″ or 6″ augers. The auger boots have a cleanout access cover.

The poly grain bins have a 16″ hole in the bottom cone and come in a variety of sizes:

All of the plastic grain bins at Barn World have a sturdy ladder with a slip guard. It is braced securely to the top of the tank near the filler cap.

All hardware is supplied and the erection time is one-third of steel bins. The top cone section bolts to the bottom and then the legs are assembled before standing up.

Frames have a baked-on polyester powder coat finish that resists corrosion.

It is recommended that you use a concrete pad at least 5 1/2″ thick for our 4.5 ton thru 8.5-ton units. The foundation needs to be able to support not only the load in the bin but also high winds when the weather gets gusty.

Please visit BarnWorld today and change out not only the bins, but the wide variety of farm supplies, ranch supplies, and equestrian supplies made by American manufacturers. Our best-selling items are hay feeders, cattle guards, feed bins, saddle pads, mineral feeders, livestock scales, and many livestock supplies.
