40 ft storage container has tough construction Did you know that portable steel storage containers are used almost exclusively by the military for all of their shipping? They even fit them up to be on-site buildings, latrines and living quarters. Often called Connex boxes, these units are made tough enough for the military, so they are certainly adequate for your storage needs. The base consists of wood plank, reinforced with cross beams and raised a good 6 inches above the ground. Made from corrugated steel or aluminum, each container has double doors (for convenient access) and a lock box for added security. Constructed to take a beating from the elements, each one of our portable moving and storage containers is also guaranteed wind and water resistant. While our 40 ft storage container is the most popular, we also have units available in 20 ft sizes.
