How Long Do Shipping Containers Last?

Since shipping containers offer an extremely durable construction, they are some of the longest-lasting storage and shipping options available. However, every good product still has an expiration date. Fortunately, 20’ and 40’ shipping containers last an average of 25 years or more.

Shipping Container Construction 101

Depending on what you use it for and how you take care of it, shipping containers can last even longer. A container used at sea for bringing cargo back and forth might last less time due to the heavy use and elements of the sea (wind and salt lead to erosion over time); meanwhile, a lightly used and well-cared-for container can last over 40 years in the right conditions.

How to Ensure Your Shipping Container Holds Up for Years

Ensuring your shipping container lasts for years is the best way to get your money’s worth. However, containers won’t maintain their original integrity if you don’t take the proper precautions.

Here are some of the best ways to protect your shipping container and ensure you get years of use from it:

Solid Foundation

First things first, find a level surface off the ground to place your shipping container. This ensures that your 40’ or 20’ shipping container isn’t in constant contact with moisture and the ground — if left in direct contact with the ground, this causes faster corrosion from groundwater and soil corrosion.

Routine Cleaning and Maintenance

Regular cleaning and maintenance ensure your container lasts for years of use. Here are some practical options for maintaining your container:

  • Remove dirt and debris from the exterior
  • Check for rust damage and fix it promptly
  • Add lubrication to metal hinges and locks
  • Ensure water and debris don’t pool on the roof
  • Re-caulk worn out areas as needed

Extra Elemental Protection

Adding extra protection from the elements (rain, snow, dirt, etc.) is essential for ensuring your 40’ or 20’ shipping container lasts as long as possible. These are some useful practices and preventatives to keep your container thriving:

  • Apply a rust resistant coating
  • Try exterior paint and coating to prevent wear
  • Opt for moisture-resistant paint
  • Ventilate properly to resist mold

General Care Tips

On top of the foundation, maintenance, and elemental precautions, there are some general care tips that keep your 20’ or 40’ shipping containers in the best condition. Here are the best ways to protect your containers for years to come:

  • Fix dents and scratches with sealant
  • Re-level and add supports as needed
  • Don’t place excess weight on the roof
  • Use dehumidifiers to reduce moisture

Should You Rent or Buy Shipping Containers?

Now that you know the answer to the question, how long do shipping containers last, you might be wondering whether you should rent or buy a container for your particular use or project. If you want to invest in a shipping container that will garner you years of use, buying a shipping container is a great option if it’s in your budget. While the initial cost of shipping containers is higher this way, it’s a great investment and ends up being the more affordable option in the long-term. 

Otherwise, if you only need it for a short time or your particular project(s), renting a shipping container might be your best option. While either way is fine, buying a container is often more affordable in the long run and better worth your investment since you get to keep the shipping container for as long as you need it.
