120’ x 200’ Steel buildings are popularly used for commercial buildings. The interior space can be subdivided for multipurpose uses, and there aren’t any interior columns to restrict the division of space. Large overhead doors can be added on either side for drive-through capabilities, and many customers add interior mezzanines for a second floor. These buildings make excellent storefronts, large churches, warehouses and storage facilities. 120’ x 200’ buildings are also used as riding arenas for customers who want to have more covered space for their horses. Other advantages offered by Great Western Building Systems include a lifetime structural warranty, engineered foundation designs, and a project manager that works with you to finalize your building design.
