NPSA members offer portable storage containers in standard lengths of 5 ft, 10 ft, 15 ft, 20 ft, 22 ft, 25 ft, 35 ft, 40 ft, 45 ft, and 53ft.

Every portable storage container or shipping container is made from cor-ten steel. Corten Steel |COR-TEN® is a type of weathering steel that resists corrosion and typically exhibits a 50 ksi minimum yield strength. Corten steel has become the standard for shipping containers, steel bridges, and buildings that are exposed to a marine environment. Since every shipping container is built to withstand the very harshest conditions on the open ocean and in the container yard, they easily protect your valuable items. Every storage container is secure, durable, and strong.

​Portable storage containers are constructed with 12 and 14 gauge corrugated steel sides, steel framing, and 1 1/8'' thick marine plywood floors. Standard storage containers come with cargo doors on one end of the container. The cargo doors seal tight from rodents and inclement weather. They also allow you to access to the entire end of the container when fully open, making loading and unloading very large items a breeze!
