Why Don’t Shipping Containers Rust? The Power of Corten Steel
Shipping containers are known for their robustness and ability to withstand the harsh conditions of transportation and storage. One of the key factors contributing to their longevity is their resistance to rust. In this blog post, we will delve into the reasons why shipping containers don’t rust and explore the significance of Corten steel in their construction.
Rust is a common form of corrosion that occurs when iron or steel reacts with oxygen and moisture in the presence of certain impurities. This chemical reaction leads to the formation of iron oxide, resulting in the familiar reddish-brown coating on the surface of metals.
Shipping containers are typically made from a type of high-strength, low-alloy steel known as Corten steel (also called weathering steel). Corten steel is primarily composed of iron, but it also contains small amounts of copper, chromium, and nickel. These alloying elements work in conjunction with the steel to create a protective oxide layer, inhibiting further corrosion.
When Corten steel is exposed to the elements, it undergoes a natural oxidation process. The surface of the steel reacts with the atmospheric oxygen to form a thin, adherent layer of rust-like patina called “stable rust.” Unlike ordinary rust, this patina acts as a protective barrier against further corrosion, making Corten steel incredibly resistant to atmospheric weathering compared to other untreated alloys.
Shipping containers, despite their resistance to rust, do undergo corrosion over time due to exposure to various environmental factors. While Corten steel provides enhanced durability and a protective oxide layer, it is not entirely immune to the effects of corrosion. Factors such as extreme weather conditions, saltwater exposure, and poor maintenance can contribute to the gradual deterioration of a shipping container.
It’s important to note that shipping containers have a typical lifespan of around 25 years, after which they may become structurally compromised or no longer suitable for their intended use. When containers reach the end of their operational life, it is crucial to handle their disposal responsibly to minimise environmental impact. When it comes to end-of-life containers, our experienced professionals ensure that the recycling process adheres to local regulations and industry standards. We prioritise sustainability and work towards minimising waste while maximising the reuse of materials.
Shipping containers don’t rust due to the exceptional corrosion resistance of Corten steel. The alloy’s unique composition, combined with its ability to form a protective patina, allows shipping containers to withstand the rigors of transportation and exposure to diverse weather conditions. Choosing Corten steel for shipping container construction ensures increased longevity, structural integrity, reduced maintenance needs, and environmental sustainability.

The Queen’s Green Canopy (QGC) invited everyone across the UK to plant trees to mark Queen Elizabeth’s Platinum Jubilee in 2022. Following her death in September 2022, the initiative was extended to give more people chance to honour Her late Majesty, her long service and legacy.
