Profile: Advantage Structures LLC. specializes in modifying new and used shipping containers. Our services include installing roll-up doors, protecting entry with lock-boxes, adding windows, hinged doors and creating non-standard container sizes. We can design and modify the container project at a fraction. Our custom shipping containers are sturdy and weatherproof and are used in variety of applications. Our containers include shipping containers, mobile storage units and portable storage containers. These containers are designed to withstand the rigors of trans-oceanic passage on the decks of ships. Steel construction and watertight door gaskets make storage containers nearly impervious to moisture penetration, vermin infestation, rot, decay, and excess humidity. We also offer electrical packages, side vents, area cut outs for prefab housing, shelving brackets, tack room applications, framing / insulation and cargo doors.
