Great Lakes Kwik Space has semi-trailers suitable for commercial and industrial storage. Although they are no longer adequate for road usage, these semi-trailers have been maintained in wind and water tight condition. Semi-trailers are a more flexible and cost-efficient storage option than going through the process of acquiring warehouse or shop space. Utilized by many commercial and industrial firms, storage trailers are perfect for uses involving loading and unloading at dock level rather than ground level.
