Question 1

What is a conex box?

Accepted Answer

"Conex" is the military term for a Container Express box — the steel intermodal container used by the US Army from the 1950s. Today it simply means a standard ISO shipping container: the same 10ft, 20ft and 40ft steel boxes used for freight and storage.

Question 2

How much does a conex box cost?

Accepted Answer

Used conex boxes start around $919 for a 10ft, $1,095 for a 20ft and $1,169 for a 40ft. One-trip units start around $2,259 for a 20ft. Delivery is quoted separately by ZIP code.

Question 3

Is a conex box the same as a shipping container?

Accepted Answer

In everyday use, yes. Contractors, farmers and military users tend to say conex box; freight and logistics people say shipping container or ISO container. They describe the same corten steel unit.

Question 4

What sizes do conex boxes come in?

Accepted Answer

Standard sizes are 10ft (80 sq ft), 20ft (160 sq ft), 40ft (320 sq ft) and 40ft high cube with an extra foot of headroom. 45ft units exist but are less common and harder to transport.

Question 5

How secure is a conex box?

Accepted Answer

Very. Corten steel walls, welded corner posts and cargo lock bars resist forced entry, and we can add a lockbox that shrouds the padlock, high-security puck locks and welded bars over any vents.

Question 6

What foundation does a conex box need?

Accepted Answer

Support under the four corner castings on a level surface — compacted gravel, concrete piers, railroad ties or a slab. Level footing keeps the doors aligned and prevents water pooling underneath.

Question 7

Can conex boxes be stacked?

Accepted Answer

Yes — they're engineered to stack up to nine high loaded at sea. On the ground, stacking two or three high is common with twist-lock connectors and a properly engineered base.

Question 8

How is a conex box delivered?

Accepted Answer

By tilt-bed truck onto a prepared pad, which needs roughly 60 ft of clearance for a 20ft and 100 ft for a 40ft. Where access is tight we arrange a crane or side-loader. In-stock units ship in 7–10 business days.
