40ft Standard Used Shipping Container
Delivered in 3–7 business days
Dry inside but not export-rated. Strong choice for storage and rougher builds. A 8'6" outer wall on this 40ft Standard shell - perfect for workshop with loft.
The 40ft Standard WWT is the most square footage per dollar in the Aurora yard. You lose the CSC plate and the cleaner cosmetics of a Cargo Worthy, but you keep what actually matters for a non-shipping use: a dry interior, gasketed doors that latch, and a floor with no soft spots or punch-throughs.
For owner-builders, this is where a long workshop conversion starts to pencil out. Hobby farmers from Strasburg and Byers buy these for hay and tractor storage where appearance is irrelevant. Aurora-area construction contractors use them as long-term materials lockers on the back of large lots. Anyone running a backyard pottery studio, a 40-foot home gym, or a budget garage shop where you plan to clad over the interior anyway gets full value out of the grade.
Plan on a long weekend of prep - sander, rust converter, two coats of direct-to-metal paint - before any conversion work begins. After that, the box behaves identically to a unit that cost $400 more.
