What is a Shipping Container

When we talk about shipping containers, we mean the steel cargo boxes used for global freight. You see them stacked at ports, on rail cars, and on flatbed trucks. They are also known as ‘storage containers,’ ‘sea cans,’ or ‘conex boxes.’ No matter the name, they all refer to the same durable steel structures designed to handle weather, transport, and heavy use.

The 20 foot model is the workhorse of the container world. Many families, farmers, small businesses, and contractors look specifically for 20' storage containers for sale because they provide solid capacity without taking up too much space.

How Shipping Containers Are Made

Shipping containers are built from a specialized steel known as Corten steel, a weathering steel engineered for extreme durability. Corten steel is designed to develop a controlled surface rust that protects the structural steel beneath it, preventing deeper corrosion over time. This same material is commonly used in bridges, seawalls, ships, and rail infrastructure, where long-term exposure to harsh weather and salt environments is expected.

Rather than relying on a protective coating beneath the paint, the strength of a container comes from the steel itself. During manufacturing, large sheets of Corten steel are cut, shaped, and welded into panels that form the walls, roof, and doors. The exterior is then finished with a direct-to-metal paint, the same type of industrial-grade paint used on ships and trains. This paint provides additional protection and visibility, while the Corten steel underneath ensures containers are built to withstand decades of heavy use and exposure.

This construction process ensures containers remain weather resistant, secure, and long lasting. At Container One, buyers benefit from a strong warranty that supports dependable use for many years.
