Grain and Seed Storage Tanks

Large XL (Flat Bottom) Grain Tanks
In the Ag market, USA Tank offers process tanks known as XL Grain Tanks. These flat bottom grain tanks are industrial process tanks that run up to 200’ diameter with storage capacities up to 1.7 million bushels. XL Grain tanks are an economical choice when compared to other types of quality containment including field-welded and slip-form concrete.

The USA Grain Tank Advantage:

• Bolted flanged panel (API) construction
• Bolted flat panel construction
• Baked-on factory coatings
• ISO 9000 quality system certified
• Designed for the specific codes applicable for your region
• Center discharge & off-center discharge designs available
• Side load-out designs
• Quick field installation by direct USA Tank crews
• Immediate mobilization available worldwide
• Field welded and bolted deck construction available

(Note: Under 105’ diameter, corrugated construction is predominant in flat bottom grain storage applications. Corrugated tanks reflect marginal design standards and light weight construction. At best, corrugated is recognized as an inexpensive cover for grain piles and is not considered a process tank (tank designed for continuous throughput). At USA, we only offer process designs that are based on certified design parameters as recognized by IBC, UBC, ASCE, etc. We do not offer corrugated construction.)

Hopper Tanks & Meal Storage
USA Tank supplies special hopper bottom tanks for meal storage applications. We offer meal tanks that provide reliable flow with the benefits of low maintenance. Gravity, functional mass flow hopper designs and selection of the correct type of discharge feeder are the keys to low maintenance meal storage that works.

The USA Advantage:

• Tank diameters range from 8’ – 38’ diameter (up to 100,000 cubic feet)
• Hopper slopes that range from 65-75 degrees
• Rectangular (chisel) discharge outlet
• Tanks are designed for mass flow product loads
• Tanks can be designed for functional mass flow discharge
• Feeders are designed to discharge product across the entire cross-section of the hopper outlet
• Specialized coating systems are utilized for flow promotion
• Material testing is available

An alternative design for meal storage utilizes a flat bottom tank and a revolving screw or drag unloader. In this approach, a mechanical unloader undercuts material across the base product zone area. At USA Tank, we design these silos for mass flow loads and off-center discharge. Based on the application, there are merits in this approach with difficult to flow materials.
