A regular 20' container has 160 sq feet of storage space. Piling everything on the floor creates a mess and is disorganized. Installing a shelf system frees up a lot of space and gives you up to an additional 160 sq feet. That is a total of 360 sq feet of storage area, the same as a 40' container! Contact us and we can build a container that will organize your stuff. Pricing is $1000 for a 3 shelf side giving you 80 sq feet of storage space.
