Shipping containers are large, standardized boxes used to transport goods across various modes of transport, including ships, trucks, and trains. They are typically made of steel and come in different sizes, with the most common being 20-foot and 40-foot containers. Their design allows for easy stacking and handling, making them essential for global trade. These containers are crucial for the logistics industry, as they protect cargo from damage and theft during transit. They can hold a wide range of products, from electronics to food, and are often reused multiple times, contributing to sustainability in shipping practices.
