Unless you live in an earthquake-prone city, wind and water are the two main elements that will affect a shipping container. When choosing a shipping container for your storage needs, you’ll want one that is wind and watertight so that your stuff remains protected during heavy or irregular weather systems.
Are shipping containers watertight?
The main purpose of shipping containers is to transport goods across the ocean. This is mostly done on the decks of large vessels. Because the decks of the ships are exposed to the elements, containers are equipped with heavy-duty rubber door seals that keep water and wind out. So yes, shipping containers are watertight. When shipping containers are repurposed for personal or company storage use, they are inspected and repaired before they are sold or rented out in order to ensure that the watertight seal isn’t broken. You can purchase or rent a used container that has a damaged seal for a reduced price, but it may simply not be waterproof and watertight anymore.
What’s the difference between watertight and waterproof?
A container that is watertight is made with materials that do not allow water to enter it. Watertight containers can also lock water in to allow for the transportation of liquid. Conversely, a container that is waterproof means that it is coated in a substance that makes it resistant to water. However, a container that is simply waterproof and not watertight can still let water in. For instance, if rain hits the outside of a waterproof container, there will be no damage. But if rain seeps into a waterproof container, its contents will incur damage.
Are shipping containers affected by condensation?
Older watertight containers can be affected by condensation if they are placed on damp ground and subject to temperature variations. The dampness of the soil will penetrate the metal container and create condensation inside it. Nevertheless, the corrugated construction and the paint used on modern containers reduce the amount of condensation that accrues so that it’s basically non-existent. If you do have an older watertight container, you can use a venting system or open the door on a dry day to force the condensation out.
Before you buy or rent a shipping container, explain to the container company what you’ll be using it for and that you want one that is watertight. This will help them determine which type is right for your needs.
