A marine container is a large, standardized metal box used for transporting goods over sea, land, and sometimes air. These containers come in various sizes, with the most common being 20-foot and 40-foot lengths. They are designed to be durable and weather-resistant, ensuring that the cargo inside remains safe during transit. Marine containers are essential for global trade, as they facilitate the efficient movement of products between countries. They can be easily loaded onto ships, trucks, and trains, making them a versatile option for shipping. The use of marine containers has significantly streamlined the logistics of international shipping, contributing to the growth of the global economy.
