20ft 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 20ft Standard shell - perfect for backyard office or studio.
The 20ft WWT trades the CSC certification of a Cargo Worthy unit for a noticeably softer price tag. Mechanically, the box still does its main job: it keeps weather out. We pressure-check the seams, verify the door gaskets seal flat, and confirm the floor is bone-dry before any WWT unit leaves the Aurora lot.
What you’re paying less for is curb appeal. Expect more pronounced surface rust on the side panels, deeper dents from years of port handling, and faded carrier paint that’s seen a couple of winters in the Rockies. For a unit destined to become hay storage outside Bennett, a tool locker behind a Watkins shop, or a fenced-job-site box for a residential contractor, none of that matters.
Owner-builders also pick WWT for prototype tiny-home builds and weekend workshops where the steel is just the starting envelope. Plan on a weekend of wire-wheel work and a coat of rust-converter primer before paint, and you’ve got a 150-sq-ft envelope for less than the cost of a steel storage shed at the big-box store.
