Bulk, Flat Grain & Fertilizer Storage Buildings

Fabric buildings are ideal for storing corn, flat grain storage, fertilizer, minerals and bulk commodities.

Maintaining a cool temperature results in higher-quality grain and corn. Fabric cladding is naturally non-conductive – instead of magnifying heat from the outside as a steel building, fabric better retains the inside temperature. In fact, inside a membrane building will feel up to 20 degrees cooler on a summer day. The storage building also acts as a shade, maintaining a cooler temperature during hot sunny days.

Architectural fabric is naturally corrosion-resistant – an important factor when storing bulk fertilizer or other corrosives. Solid steel frames are less likely to corrode than open-web trusses, and hot dip galvanizing (HDG) further prevents corrosion. Adding a fabric liner inside the building keeps the steel beams out of contact with the elements, and provide a clean finish inside the building.

Incorporating other materials, such as concrete, is common for flat grain storage and other bulk materials. Combining a cast-in-place or pre-cast foundation and a concrete knee wall provides the side wall strength needed for bulk storage. Topping the storage structure with a partial fabric wall and fabric roof allows light and ventilation into the building while keeping moisture and birds out.

Adding a grain liner can increase the storage capacity without increasing the building footprint or the cost per bushel. Steel or wood grain liners are available and can be engineered into the building for efficient storage.

Commodity Fabric Structures

Ventilation is a common concern when storing commodities, especially corn and flat grain storage buildings. There are a number of ventilation options for fabric structures. Open end walls or end wall vents are a simple solution, but that does not always provide the needed ventilation in the center of a large building. Peak ventilation combined with mesh vents under the overhangs provides a constant stream of cool, fresh air – warm air will be pushed above the grain and out the peak, and fresh air will come in through the sides. The ventilation provides a constant stream of cool air and eliminates dead spots in the center of the building. Exhaust vents at the peak keep birds and other pests out of the building.

Design-built structures easily accommodate dynamic loads from cranes and conveyors. Bridge conveyors added to the building frame result in even filling in the flat grain storage structure. Tension fabric storage buildings provide the ideal flat-grain storage for bulk commodities including grain, corn and even fertilizer. The inside of a fabric structure is a cool, clear span environment that will allow for maximum storage capacity at a low price.
