Shipping containers are not only well built, but they are durable. Durable enough that shipping containers are now being used as storm shelters; people are building homes with them; and even modified into swimming pools. They are built to last!
Shipping Containers are the Superman of Storage
These almost indestructible boxes are made of weathering steel better known as Corten steel. It is a type of steel that was developed to resist harsh weather and corrosion, more so than other types of steel. For this reason, it is often used for outdoor structures like bridges. An unmodified container will be wind and watertight but will still be susceptible to rusting. It’s known for toughness and longevity, however it’s not invincible. The panels of a storage container are corrugated which provides added strength. These panels are then welded onto reinforced steel beams. Next comes the doors and flooring. The flooring is made of 1-1/4″ marine grade plywood adding additional durability to the unit.
Lifespan of a Shipping Container
Shipping containers have many benefits and one of the most important ones is their lifespan. Generally, a used container can last 10-12 years at sea and long beyond that after it’s retired from the cargo ships. When maintained properly, a shipping container can last upwards of 25 years or longer. The lifespan depends on the condition of the container and the environment in which it is kept. Although they are built to resist harsh climates, its’ lifespan can be cut short by wetter, saltier climates. To maximize the life of a container is to minimize the exposure to moisture. Storing a container off the ground prevents the base of the box from sitting on a damp ground and absorbing moisture.
There are a few other measures you can take to increase the sustainability of your container. For instance, you can have it refurbished. You can have the rust removed, then have it primed and painted. Routine inspections and cleaning the unit for rust will also help.
