20ft Shipping Container

Product overview

A 20ft used shipping container — also called a 20-foot conex box, conex container, or cargo container — is a pre-owned steel storage unit you own outright, and the most cost-effective way to add secure, weatherproof storage that lasts for decades. It is our most popular size: roomy enough for a small home's worth of belongings, a vehicle, or a full job-site of tools, yet compact enough for most driveways and lots.

Is a used container still reliable? Yes. Our used units are structurally sound and sealed against rain and pests, with years of service left. Built from corrosion-resistant Corten steel with a marine-grade plywood floor and lockable cargo doors, a used conex protects your gear just as well as a new one.

What should I expect? Honest cosmetic character — minor dents, scuffs, and surface rust from years in shipping. None of it affects performance. Ideal for on-site tool and equipment storage, farm and ranch supplies, garage overflow, retail backstock, jobsite security, or a custom build.
