A Conex box is a type of cargo container that was developed during the Korean War to transport and store supplies. It is made of Corten steel and is designed to withstand harsh environments and protect goods while they are shipped around the world. The name "Conex" is a blend of "container" and "express," and it is a shipping container by another name. The standard sizes of Conex boxes are 20 and 40 feet, and they can be stacked three high. They are modular and can be used for various purposes, such as construction storage, personal storage, commercial building projects, and residential units. Conex boxes are also used to transport heavy materials or palletized goods by sea, rail, and road, making intermodal transport possible. They are sold in a variety of conditions, and its important to know what those conditions are and if your intended use of the container aligns with the appropriate condition.
