Cargo containers are large, standardized boxes used for transporting goods across various modes of transport, including ships, trucks, and trains. They are designed to be easily loaded and unloaded, making the shipping process more efficient. Typically made of steel, these containers come in different sizes, with the most common being 20 and 40 feet long. These containers help protect the contents from damage and theft during transit. They are also stackable, allowing for efficient use of space on cargo ships and in warehouses. The use of cargo containers has revolutionized global trade, facilitating the movement of products around the world.
