Conex Box For Sale
Military-spec steel conex boxes from $919 — 10ft, 20ft and 40ft, used or one-trip, delivered to your site in 7–10 business days.
Conex — short for Container Express — is what the Army called the steel boxes it moved supplies in, and the name stuck. What you're buying today is a standard ISO shipping container: Corten steel, welded corner castings, marine plywood floor and cargo doors rated to keep weather and thieves out.
We sell conex boxes in 10ft, 20ft and 40ft, in used wind- and watertight, cargo-worthy and one-trip condition. Every unit is graded and photographed against its container number, and delivery is quoted with the box so the price you approve is the price you pay.

Corten steel shell
Weathering steel that forms a protective oxide layer instead of rusting through, with corrugated panels welded to a heavy steel frame at all eight corners.
ISO standard sizes
8ft wide and 8'6" tall as standard (9'6" on high cubes), with ISO corner castings so any crane, side-loader or twist-lock chassis can handle them.

Cargo lock bars as standard; lockbox shrouds, puck locks, additional lock plates and welded vent bars fitted in our yard before delivery.
Nationwide placement
Tilt-bed delivery across the lower 48, with crane or side-loader placement arranged where the site can't take a tilt-bed approach.
