Are shipping containers waterproof and weatherproof?

If you intend to store your belongings in an outdoor steel box, this should be your very first concern. Are my belongings going to remain dry even if it rains? The answer would be yes, but there are a few more details that you need to know prior to purchasing a container.

Designed for the sea

Shipping containers have been designed with transportation at sea in mind. They spend weeks on the deck of ships exposed to rain, waves, and high winds. This means that these containers come with heavy-duty steel walls and rubber gaskets in the doors. It will be easy for good condition shipping containers for sale to remain dry during the rainy season, hence their popularity in protecting tools, supplies, and furniture.

Waterproof or water resistant?

This needs to be said straightaway: although the container is highly resistant to water, it is not waterproof indefinitely. It will be dry for several years. The problem will lie in door seals, vents, as well as rust spots and dents that may appear over time. An old container with rust spots will allow a little water inside in a downpour.

The age of the container and its condition have a big impact here. Thus, in a humid region, a newer one is definitely a better choice.

What about wind, heat, and cold?

Steel is quite resistant to the climate. The filled container will not move in a storm; however, it is better to secure it in places that are prone to cyclones. Heat will not affect the box, but it may become very hot in summer.

Another problem arises when it comes to cold weather – it is condensation. Moisture is formed on the cold roof from the warm air inside the box; moisture falls like light rain. Container rain is what some people call it.

Easy ways to keep your container dry

  • Place it on level ground and raise it slightly using blocks or bricks.
  • Ensure that the floor of the storage is slanted to ensure that water does not accumulate on the roof and flows out.
  • Test the seals of the doors twice a year and replace them where necessary.
  • Install vents to allow circulation of air within the storage unit.
  • Store the goods on pallets rather than the floor.
  • Use silica gel packets in the storage area.
  • Treat minor rusting areas using rust paint.

Only need it for a short time?

If you just need space for a few months, shipping container hire can be a smart choice. You get a dry, secure box and don’t have to worry about what to do with it later.

Need more than storage?

Some jobs need a space that stays dry and comfortable, like an office, cafe or workshop. In that case, shipping container modifications such as insulation, extra vents, and proper lining can fix condensation and heat problems. For a small garden shed or tight space, 10ft shipping containers are a good fit. And if you are not sure how much room you need, check the shipping container dimensions before you decide.

The bottom line

Cargo containers are strong and can withstand almost all kinds of weather. However, they do not have magic powers either. Simply select a well-maintained cargo container and put it up properly. This way, your cargo will remain secure and dry for many years to come.
