Conforming to ISO standards
ISO is the International Standards Organisation, and is responsible for setting down the standards to ensure that shipping containers can travel without being a safety hazard or causing damage to other shipping containers in transit. This is important when you realise that shipping containers are stacked, often up to eight high for the journey overseas. Without rigorous standards governing size and suitability this could be disastrous! This is why you will notice nearly all containers for export are a standard width of 8ft wide and either 20ft
long. The height of the container is not really an issue for safe transportation, but most are 8'6" high. However, high cube containers
with a height of 9'6" are becoming increasingly popular.
