Grain Elevators-Builders is a subdivision of the General Contractors-Industrial Buildings and Warehouses industry. This industry involves the construction of grain elevators, which are facilities used for the storage and transportation of grain. Grain elevators are typically tall structures that consist of a headhouse, a vertical storage space, and a base. The headhouse contains the machinery used to move grain, while the vertical storage space is where the grain is stored. The base of the elevator is where the grain is unloaded and loaded onto trucks or trains. Grain Elevators-Builders are responsible for the design, construction, and maintenance of these facilities.
