Containerized, rigid-wall shelters are an excellent alternative to permanent construction and provide temporary structures that are significantly more energy efficient and comfortable than tent-based shelters. SEA BOX's Expeditionary Shelters are designed to be functional and easily deployable and can be ISO certified and transported anywhere in the world via land, sea or air. SEA BOX shelters are constructed of heavy-duty steel frames which ensure a sturdy and robust ISO structure. Panel design can vary in thickness and composition depending on the shelter’s purpose. We offer shelters that expand on one or both sides to maximize usable space as well as collapsible shelters that are designed for transportation efficiency. From command and control centers to shower and latrine facilities, our shelters can provide a functional solution for military field operations, camps or commercial needs.
