Every shipping container is designed to endure harsh marine environments as they sail across the globe. Because they’re exposed to the elements in such a way, this makes them pretty tough.

Their exteriors are primarily steel with their interiors made from mould and rot-resistant materials. The paint also helps prevent corrosion and gives them an extra layer of protection. 

Naturally, it also lends to them not needing to be maintained as much as you might initially believe. However, they will need some maintenance eventually, even after they’ve been converted. 



To keep your container in top condition, it’s important to look after it and give it some semi-regular maintenance. Here are five things to keep an eye on with your container. 

1) Inspect the Roof

The first and most integral part of the shipping container to keep on top of (literally) is the roof. Second-hand containers especially often come through dented and slightly battered with other containers resting on top of them. 

Dents can collect rainwater, which can lead to corrosion and chipped paint. Naturally, this will lead to gaping holes in the roof, which is a problem for many different reasons. To prevent this, you can either replace the roof or give it another coat of paint. 

2) Lubricate the Doors

The next thing to keep maintained are the doors. While a converted shipping container may have entirely different doors than their original, this is still a priority as it is the primary means of access into your container. 

The most important thing is to clean and lubricate them. Make sure the hinges are intact and make sure that there is no rust in between the joints. Otherwise, it will be very difficult to get inside it. It will also be difficult to close. 

Our suggestion is to use copious amounts of WD-40 lubricant spray and a good quantity of grease. As with any moving parts, they are subject to damage and should keep an eye on, especially if it starts squeaking. 

3) Treat the Rust

Because they are steel, many shipping containers are at risk of rust. This is why they are always covered in a layer of paint. Of course, this helps delay the onset of rust quite a bit, but there is always a chance that it can come through, especially as it would’ve been exposed to salt-air environments. 

Look out for any dents, scratches or cuts that have been left exposed. Be sure to seal them up immediately with another coat of paint if necessary. This will ensure the lifespan of your container will last a lot longer. 

Naturally, most shipping container conversions have another coat of paint as part of the conversion process so this may not be a problem for many. However, it’s a good idea to keep on top of it. 

4) Ensure Evenness 

This should go without saying, but the secret to any sound construction is to make sure your container is resting on level ground. 

The surface must be drained too to prevent water leaking through the floor. It also avoids water collecting in one area of the container. 

5) Check Container Modifications 

Whatever you choose to do to your container, conversion or not, be sure to pay as much attention to the modifications and customisations as you would the rest of it. This is especially relevant if you have any extra doors, windows or other openings. 

Look, too, for any depressions or areas that are likely to collect dirt. Remove any rust in that area also and treat it with anti-corrosive paint.
