A container is a standardized shipping container that is widely used in sea, land and air transportation. They are usually made of strong steel and are waterproof, rust-proof and corrosion-resistant, ensuring the safety of goods during transportation. Containers are designed for easy loading and unloading, with common sizes of 20 feet and 40 feet suitable for different types of cargo. In recent years, containers have also been innovatively transformed into houses and commercial spaces, demonstrating their flexibility and versatility, becoming an important part of modern architecture and logistics.
