Shipping containers are large, standardized boxes used to transport goods across various modes of transportation, 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 secure loading, making them essential for global trade. These containers are crucial for the logistics industry, as they help streamline the shipping process and protect cargo from damage. They can hold a wide range of products, from electronics to food, and are often reused multiple times, contributing to sustainability in transportation.
