Shipping containers have revolutionized global trade. Before the invention of shipping containers, loading and unloading ships took a long time, and space was often used inefficiently. It should come as no surprise then that Container Home Hub reports global cargo shipping reached 1.85 billion metric tons in 2020, up from 0.1 billion metric tons in 1980. Yet while modern shipping containers have improved trade, they’re still an investment, even if you pick them up during a shipping containers sale, and you may wonder just how long they’ll last.
The Expected Lifespan of a Shipping Container
In ideal conditions, a shipping container can last 25 years or more. However, “ideal” is the keyword. For shipping containers to last this long, you’ll have to minimize exposure to the elements and other risk factors. Proper maintenance and regular cleaning will also be needed to maximize the lifespan of the container.
Many cargo companies will retire shipping containers after about 10 to 12 years. These containers are often subject to high use and constant exposure to saltwater, rain, the sun, and everything else. The high seas can be a harsh environment. You can sometimes pick up used containers during a shipping containers sale.
Shipping containers are made out of COR-TEN steel, or weathering steel as it’s sometimes called. Unfortunately, like other types of steel, weathering steel can still rust, especially if exposed to salt water. That said, Cor-ten steel is more resistant to rusting than other forms of steel.
How to Get the Most Out of Your Shipping Containers
Special paints and protective layers can be applied to protect the steel from rusting. Of course, if this paint should wear out or be damaged, then it may no longer provide adequate protection. Properly applied zinc-aluminum coatings can extend the lifespan of a shipping container by a few decades.
If you own shipping containers, you’ll want to make sure that they are well-maintained. You may need to reapply coats of paint and protective coatings. Pay close attention to hinges and other components as they are sometimes the most prone to rusting.
If you’re not going to be using your shipping container for an extended length of time, proper storage could extend its lifespan. Ideally, you’ll keep it indoors, say in a warehouse. If you can’t store it inside, protecting it with a tarp may help.
