Intermodal containers, also known as shipping containers, are large standardized steel boxes used for the transportation of goods. They have revolutionized the shipping industry, allowing goods to be transported across long distances in a safe and efficient manner.
The purpose of this blog post is to explain the various dimensions of intermodal shipping containers and their intended specific uses. Knowing these sizes is crucial for those working in the shipping industry, as it helps you select the most appropriate container for your specific requirements.
The Functionality of Intermodal Containers
An intermodal or ISO shipping container is a container that meets standards ISO and is suitable for storing and transporting materials and equipment in a global containerized intermodal freight transport system.
Typically, intermodal containers are used for transporting the following items:
- Cargo that is resistant to spoilage, such as manufactured goods.
- Intermodal transportation of temperature-sensitive perishable items, including chilled and frozen cargo like seafood, meat, agricultural products, and medicines.
- Cargo that is not likely to spoil but could potentially sustain damage during transportation due to condensation, such as coffee and cocoa.
- Transport of oversized cargo, such as construction materials, heavy machinery, and lumber.
- Bulk shipping of hazardous and non-hazardous chemicals, oils, liquids, and food commodities.
