Bucklin Buildings offers cost effective and efficient
Our Flat Storage Buildings are perfect for agricultural grains such as:
- corn storage
- wheat storage
- soybean storage
- even great for fertilizer storage
Bucklin Buildings specializes in storing grain. We are the workhorse of your storage complex. We have High Quality and Experienced Builders serving South Dakota and the Midwest States. To date we have three widths that we offer: 80, 124, and 135 feet.
Fabric Structures for grain storage have many benefits. Bucklin Buildings are very competitive and are built to be the strongest available.
Bucklin Buildings is your Midwest Grain Storage builder.
Using Flat Storage Buildings for Dry Grain in years when grain yields are high and prices are low, it is worth considering use of existing flat buildings (machine storage buildings, warehouses, or even livestock buildings, for example) for temporarily storing grain.
Things to consider when deciding whether a given building would be a good choice for storing grain:
Can you get the building clean enough for grain storage? If the building previously contained manure, ag chemicals, or petroleum products, can you completely remove these materials and their odors so that grain will not be physically contaminated or pick up odors that would result in down grading?
Also, take a look at the way the building is constructed and try to determine whether you can keep birds and rodents away from the grain. Wall strength. Dry grain exerts high pressure on walls, and unless the building was specifically designed to withstand the pressure of grain or some other granular product, it will need to be reinforced. If the building was designed and erected by an ag building company, you might ask the company if a “grain package” is available. Or you could consider hiring an engineering consultant to design building modifications for you. Another option would be to set freestanding bulk heads inside the building to keep grain away from the walls. Extension doesn't currently have plans for do-it-yourself bulk heads, but some local contractors or building materials suppliers might be able to build them for you. Some farmers avoid the wall-pressure problem by buying metal grain bin rings (without floors or roofs), and setting the rings inside the building.
Finally, you could accept reduced storage capacity and just place grain in the center of the building in sloping piles that do not touch the walls. Capacity. When you are trying to decide whether it is worth using an existing building for grain storage, make sure you estimate how many bushels can be stored. It is disappointing to find how few bushels can actually be stored in some flat buildings, especially when buildings have low ceilings or when grain is not piled against the sidewalls. To estimate capacity, calculate the volume of the planned grain pile in cubic feet and then multiply by 0.8 bushels per cubic foot, or divide by 1.25 cubic feet per bushel to get volume bushels.

Spring Grain Drying and Grain Storage Management
Kenneth Hellevang, Ph.D., P.E.

The storability of grain depends on the grain quality, moisture content, and temperature. Grain moisture content must decrease as grain temperature increases to safely store grain. For example, the allowable storage time of 22 percent moisture corn is about 190 days at 30 degrees, 60 days at 40 degrees, and only 30 days at 50 degrees. Therefore, as stored grain temperature increases the grain moisture content must decrease for safe storage.
Stored grain temperature increases in the spring due to outdoor temperatures increasing and solar heat gain on the bin. There is more than twice as much heat gain from solar energy on the south wall of a bin in early spring as there will be during the summer.
Immature grain and grain with damage to the seed coat is more prone to storage problems, so the grain should be stored at a lower moisture content than normal. Also, stored grain should be monitored more closely to detect any storage problems early. Grain temperature and moisture content should be checked every two weeks during the spring and summer. Grain should also be examined for insect infestations.
Corn needs to be dried to 13% moisture for summer storage to prevent spoilage. Soybeans should be dried to 11%, wheat to 13%, barley to 12% and oil sunflower to 8% for summer storage.
Check the moisture content of stored grain to determine if it needs to be dried. Remember to verify that the moisture content measured by the meter has been adjusted for grain temperature. In addition, remember that moisture measurements of grain at temperatures below about 40 degrees are not accurate. Verify the accuracy of the measurement, by warming the grain sample to room temperature in a sealed plastic bag before measuring the moisture content.
Grain temperature should be kept cool during spring and summer. Periodically run aeration fans to keep the grain temperature below 40 degrees during the spring.
Grain storage molds will grow and grain spoilage will occur in grain bags unless the grain is dry. Grain in the bags will be at average outdoor temperatures, so grain will deteriorate rapidly as outdoor temperatures increase, unless it is at recommended summer storage moisture contents.
Corn at moisture contents exceeding 20% should be dried in a high temperature dryer because there is potential for corn field molds to continue to grow at moisture contents exceeding about 20% when grain temperature increases above about 40 degrees. For natural air-drying, assure that the airflow rate supplied by the fan is at least 1.0 cfm/bu. and the initial corn moisture does not exceed 20%. Start drying when outside air temperature averages about 40 degrees. Below that temperature, the moisture holding capacity of the air is so small that very little drying occurs.
An airflow rate of at least 1.0 cfm/bu. is recommended to natural air dry up to 16% moisture soybeans. The expected drying time with this airflow rate will be about 50 days. The allowable storage time for 18% moisture soybeans is only about 40 days at 50 degrees, so a minimum airflow rate of 1.5 cfm/bu. is recommended to natural air dry 18% moisture soybeans.
