Renowned for their durability and versatility, shipping containers make excellent storage and shipping solutions. However, to ensure they continue to serve their purpose effectively and securely over the long term, you need to carry out regular maintenance.
Just like you would with any other investment, you need to take proper care of your shipping container to extend its lifespan and maintain its structural integrity.
Let’s take a look at the crucial maintenance practices that will help you preserve the functionality and security of your shipping container so that it remains a reliable asset for years to come.
How shipping containers fall into disrepair
For stationary shipping containers, the main reason for damage is rust. Despite their robust construction and being designed to endure the harsh maritime environment, they’re not entirely impervious to the elements. Prolonged exposure to moisture (rain, snow or humidity) can lead to rust developing on the surface. Over time, this will cause corrosion and weaken the structural integrity of the container. Potentially, this could compromise its ability to protect your contents.
Besides rust, shipping containers can suffer physical damage from impacts. Even when these aren’t used for shipping, a container can be moved or repositioned and during this movement, it can be dropped accidentally or even struck by heavy equipment. Impacts, whether from a strike or drop, can cause dents, bends or punctures to the metal. This can exacerbate rust problems further by allowing water to get in.
Why does a damaged shipping container matter?
Damage to a shipping container can have repercussions beyond the immediate structural concerns. A weakened container is at an increased risk of leaks, which can lead to flooding and water damage to the contents. A compromised integrity also means the shipping container is more susceptible to pest infestations, including vermin, which can damage stored goods further and cause unsanitary conditions.
The appearance of a damaged container is also a consideration. This is because it can impact the perception of your business in a negative way. Customers and visitors may see a rusted or dented container as a sign of neglect. This would reflect poorly on the company’s image and professionalism. It could harm your reputation and potentially drive business elsewhere.
From a financial viewpoint, having a damaged container will also have a lower resale value. Should you decide to sell or upgrade the container in the future, visible damage and structural issues will reduce the amount you can expect to receive. By carrying out regular maintenance and making prompt repairs to damage, you preserve the value of your container so that it remains a viable business asset.
How to prevent damage to your shipping container
Preventing damage to your shipping container is important for maintaining its functionality and extending its lifespan. One maintenance technique not to be missed for rust prevention is the regular application of zinc-based paint. This type of paint gives the shipping container a protective coating that shields the metal from corrosive elements and moisture. This helps to slow down the rusting process significantly.
Another useful idea is to prop the container off the ground. You can do this by placing concrete blocks or wooden beams underneath to elevate the container and prevent it from coming into direct contact with groundwater, which causes deterioration and rust from underneath. Elevating the container also helps with ventilation, which reduces the risk of moisture accumulation.
If possible, you could also shelter the container from the elements by placing it within a larger structure or under a roof. This would then shield it from rain, snow and direct sunlight so you minimise the risk of weather-related damage and rush.
Finally, when it comes to moving the container, it’s important to handle it with absolute care. This means that you need to use proper lifting equipment like a crane or forklift so you don’t drop or strike the container and cause damage. You should also make sure it’s balanced and secure during transportation to prevent shifts or impacts that could cause dents or structural damage.
By taking precautions, you can extend the lifespan of your shipping container and keep it in optimal condition for years to come.
How to repair damage
Prevention is always better than the cure as they say, but if your shipping container has already sustained damage, it’s not too late to take action and restore its integrity. Addressing rust is the first step in repairing a damaged container. You should start by using a wire brush and sandpaper to remove the rusted areas thoroughly. Once the rust has been eliminated, apply a rust-inhibiting primer followed by a coat of zinc-based paint to protect the cleaned areas from future corrosion.
If there are holes or more significant structural damage, you can use welded steel patches to repair them. Again, the area will need to be cleaned and prepared around the hole, ensuring there is no rust or debris. Cut a steel patch to the appropriate size and weld it securely over the damaged area. This will restore your container’s structural integrity and prevent water and vermin from getting in.
When you’ve addressed any rust or holes, you should consider applying a fresh coat of protective paint to the entire container. This will ensure that it is shielded from the elements and will keep it in optimal condition.
When should a shipping container be replaced?
Shipping containers can last a long time with regular maintenance and timely repairs. However, there will come a point when a replacement becomes more practical than continued repair. To know the right time, you’ll need to assess several factors, including the size and number of holes and whether there is widespread rust. If rust is extensive, it can weaken the steel and make it so that repairs just won’t be effective or safe anymore.
Age is also a factor. If the container is old—typically over 15—20 years—it may have reached the end of its useful life, particularly if it has been exposed to harsh environments over time.
The cost of repairing a shipping container is another factor to consider. When it becomes expensive to fix holes, rust and structural damage, it may be time to consider a replacement. If you continue to invest in an ageing container, it can become a financial drain.
By monitoring and assessing your shipping container regularly, you’ll be able to make an informed decision about when it’s best to replace it.
