About Convex Containers

Convex Containers supplies used and one-trip shipping containers across the United States. We are a dealer: we buy from depots and shipping lines, inspect what we buy, and sell it on with the grade stated plainly.

What we sell

Standard 20ft and 40ft containers, high cubes, and smaller 10ft units. Some are cargo-worthy and still certified for shipping; others are wind-and-watertight units destined for storage, workshops, site offices and conversions. Every listing says which.

Where we are

2300 E Kenosha St, Broken Arrow, OK 74012. Containers ship from the depot nearest your delivery address rather than from here, which is what keeps the haulage cost down.

How we grade

Grading in this trade is inconsistent, so here is ours:

• One-trip — built for a single loaded voyage from the factory. Near new, minimal marking.
• Cargo-worthy — surveyed and certified fit for international shipping.
• Wind and watertight — sound roof, floor and doors. Cosmetic rust and dents are normal and do not affect use.
• As-is — sold with known faults, which we list. Priced accordingly.

What we are not

We sell containers as goods, delivered to you. We do not sell land, we do not site or connect units, and we do not sell container homes as property. What you do with a container after it is delivered is your business and subject to your local planning and building rules.
