A cargo container is a large, standardized box used for transporting goods across different modes of transport, such as ships, trucks, and trains. These containers are designed to be durable and secure, allowing for efficient loading and unloading of products. They come in various sizes, with the most common being 20-foot and 40-foot containers. Cargo containers are essential for global trade, as they facilitate the movement of products from manufacturers to consumers. They are often made of steel and can be stacked on top of each other, maximizing space on cargo ships and in warehouses. This system has revolutionized the shipping industry, making it faster and more cost-effective.
