Buying a shipping container: what to check

A shipping container is bought on its grade, its doors and its size. One-trip containers have made a single voyage and are close to new; cargo-worthy units are certified fit for sea freight; wind and watertight units have a sound roof, floor and doors, with the cosmetic rust and dents that are normal for that grade. Standard containers are 8ft 6in high and high cubes add a foot, which matters for racking, shelving and conversions. Decide which doors you need (cargo doors, roll-up doors or full side access), then plan the ground: firm, level gravel or concrete pads, and a clear straight run for the tilt-bed truck, roughly 60 feet for a 20ft unit and 100 feet for a 40ft.

Convex Containers is based in Broken Arrow, Oklahoma, in the Tulsa area, and sells shipping containers, refrigerated containers, container pools, portable cabins, flat pack buildings and trailers to buyers across the United States.
