Shipping containers, also known as cargo containers or freight containers, are standardized metal containers used for shipping goods and cargo around the world. Here's a detailed description of shipping containers and their key features: 1. Standard Sizes: Shipping containers come in standardized sizes to facilitate efficient handling and transportation. The most common sizes are 20 feet (often referred to as a "TEU" or Twenty-Foot Equivalent Unit) and 40 feet in length. Standard heights are typically 8.5 feet, and widths are about 8 feet. 2. Construction: Shipping containers are usually made from corten steel, which is highly durable and resistant to corrosion. They have reinforced corners and typically feature double doors at one end for easy loading and unloading of cargo. 3. Door Configuration: The standard shipping container has cargo doors at one end, secured with heavy-duty locking mechanisms. Some containers may have doors at both ends, allowing for more flexible access to the cargo inside.
