Shipping containers are large, standardized steel boxes that are used to transport goods by various means of transportation such as ship, truck, and train. They come in various sizes, with the most common being 20 feet and 40 feet long. Shipping containers are designed to be easily loaded and unloaded, and can be stacked on top of each other for efficient storage. This makes them ideal for use as storage containers, both on land and at sea. They can be used to store a wide variety of goods, including manufactured products, raw materials, and perishable items.   Shipping containers have standardized dimensions, making them easy to stack and store in large numbers, allowing for efficient use of space. Additionally, shipping containers can be converted into various structures such as storage sheds, workshops, and even homes, providing a versatile and cost-effective storage solution. They are made of corrugated steel, which allows them to be converted or modified to suit different needs.
