    Fabric Buildings for Bulk Commodity Storage—It’s All About Your Operations

    Getting dry bulk materials from point A to point B usually requires storing the materials at both points. Keeping material out of the weather is necessary, but a solution is often needed quickly. Logistically speaking, fabric structures are ideal for bulk storage, and we offer customized, durable, versatile fabric structures beyond just storage. Our building can help streamline your entire operation.

    There are two primary storage methods for storing bulk materials: horizontal (covered or uncovered) and vertical (silo, bins)

    Bulk Flat Storage

    Despite the widespread usage of both storage techniques, bulk flat storage has several advantages over vertical storage options, including:

    • Expanded capacity
    • Adaptability various operations

    Due to variable pile height and layout, bulk flat storage buildings can offer higher capacity than vertical storage structures.

    Cast-in-place or precast concrete panels offer a better load-bearing capacity, and building design can improve capacity to accommodate storage needs. This makes it possible to load materials, such as grains, fertilizer, and more, to the edges, maximizing interior space by removing dead zones.

    Clear span or free span building design is another way to increase tonnage capacity for flat storage buildings. Rigid frame design is free of interior columns that take up valuable floor space and can create obstacles for equipment maneuvering.

    Below are just some examples of specific bulk storage uses, Legacy structures can accommodate any bulk commodity need.

    Bulk Storage Commodity Options

    Sand & Salt Storage

    Bulk road salt and spreading equipment are significant investments. Wind and moisture can deteriorate the quality of stored salt and equipment – a danger that proper storage buildings can help prevent.

    Salt storage buildings should not only protect your investment but also allow for greater operating efficiency.

    Why a Legacy Fabric Building for Salt Storage

    • Fabric is naturally non-corrosive. Unlike steel, fabric can come in direct contact with corrosive elements such as salt.
    • Our steel treatment process extends the life of the building frame by providing a continuous protective barrier from corrosion and other damage. Unlike hot dipped galvanizing, which merely slows the corrosion process, EpoxxiShield™ provides a continuous protective barrier from corrosion and other damage.
    • Because fabric buildings are completely customizable, you choose the length, width, and height of your building to maximize space and reduce cost. Your building will allow for ideal pile heights, and the sidewalls and peak will be high enough to maneuver tip trucks, conveyors, and other equipment.
    • Fabric buildings are naturally well-lit. You may not need any artificial lighting during the day, and you'll use less lighting at night.

    In addition, a custom-designed fabric building ensures adequate space for piles, equipment, operations, and pedestrians — without wasted square footage. Legacy will engineer a building around your business operations-specific tonnage requirements.

    Frac Sand Storage

    Fracking supplies energy to the world. And fracking requires at least one tool in large amounts: frac sand. Tension fabric structures are the optimal building for frac sand storage.

    The building should be flexible enough to receive product via multiple modes of transportation, protect workers handling the sand, and create efficient means of load-out via truck, rail, or barge.

    A custom fabric building does all this and more. Fabric structures bring these advantages to the fracking site:

    • Freespan Area
    • Conveyors
    • Load-Out Systems
    • Energy Efficiency

    Fertilizer Storage

    Dry fertilizer coats everything in fine dust – and will corrode exposed steel. Steel buildings used for fertilizer storage can succumb to the effects of corrosion in less than a few years. Even traditional wood buildings used for fertilizer storage are vulnerable to rust at the joists and fasteners. 

    Structural fabric, including Legacy's Exxotec™ PVC fabric, has non-corrosive properties. Legacy also offers the ultimate in rust protection, EpoxxiShield frame finishes. EpoxxiShield-coated frames create a protective barrier, extending the life of the building frame. In addition to epoxy-coated structures, an interior liner can be added, creating a seal from the inside out – keeping fertilizer away from the steel frame and stopping corrosion before it happens. 

    Large-scale fertilizer operations require an abundance of free-span or clear-span floor space – including:

    • Separate bays to store various types of fertilizer before mixing,
    • More heavy equipment operating room for receiving, load-out, material handling, and segregation.

    Combining architectural fabric with the proven strength of a rigid steel frame allows building widths over 300 feet, along with any length.

    Bulk Grain Storage

    Fabric structures for flat grain storage are less expensive and easier to install than traditional steel buildings.

    fabric structure costs less than a steel structure but still provides strength and capacity to contain large amounts of grain. Legacy fabric structures are also highly customizable in their layout and shape, and fabric structure installation exceeds that of a steel building.

    Steel building construction consists of screws, creating holes and places where moisture can leak, whereas a fabric structure is weather-tight. Using a fabric building for flat grain storage is a huge benefit, as moisture and mold can ruin a grain harvest.

    Legacy's fabric buildings utilize passive ventilation, helping to keep the air fresh and moisture levels reduced to aid in decreasing an environment for mold to grow. Fabric is thermally non-conductive, which helps to keep temperatures in a fabric structure more moderated than in a steel structure. Fabric structures generally stay cooler in the summer and warmer during the winter months.

    Everything that Legacy said they were going to do, they did.

    We obviously had contracts, but the overall feel was kind of like the olden days, where you felt you could just take somebody at their word. Price is a major factor in any purchase decision. But we didn't blink at having to pay a little more for the Legacy structure. Sometimes you have to spend more to get a higher quality building. The installation was very smooth. Legacy's in-house crew worked in cold winter conditions, and they erected the building within five days. They were a very professional group, and I'd highly recommend them. We like the sidewall columns going straight up instead of curving down like in our hoop buildings. First off, it lets us put more product in there. And our front-end loaders can get much closer to the walls and drive straight down the sides. It gives us more working room and increases our efficiency. In the long run I think this will be a building that requires less maintenance. Legacy was so outstanding to work with that I didn't even bother looking at pricing elsewhere.

    The Legacy construction crew was very professional and courteous.

    Because of our soil issues, we simply couldn't afford to construct a more traditional building. The concrete costs made a more traditional building cost prohibitive. The lightweight design of our Legacy building allowed us to reach a compromise between soil conditions and cost. Regarding the design and construction phases of the building, I can say that the process went exceptionally well. When I made eleventh-hour changes to the job, Legacy handled them with ease. They finished the job well ahead of schedule, worked safely, and followed our stringent safety requirements to the letter.

    Joe Bitter Alliant Energy/IEI Barge Services

    The new building will protect the salt supply.

    It will be protected from being compromised by wind and precipitation. Once the general contractor completed the footings and floors, Legacy installed the fabric building very quickly, in about two weeks. It was a very positive process with professional communication between Legacy and Dewberry throughout the project.
