They are manufactured in a large variety of sizes and types, each designed to meet specific cargo and transportation requirements. Their length is usually 20 or 40 feet, although longer containers are used, principally in the US trade; these containers are 45, 48 and 53 feet long.

The castings at each corner of the container support the containers weight. The castings are the only points at which a container should be supported, and are used to attach securing fittings, such as lashing rods and twistlocks. The position and spacing of corner castings are carefully controlled.8

Containers that are longer than 40 feet usually have additional support points at the 40-foot position so that they can be stowed over a standard 40-foot container.

Corrugated walls can be made from plate from as little as 1.6mm (1/16 inch) in thickness. Their frame consists of side and end rails and corner pillars, fitted with corner castings. The closed end is approximately 4.5 times more stiff, in racking strength, than the door end.13
