Shipping containers are incredibly versatile building blocks for everything from pop-up shops to multistory event structures. However, their unique nature leads to some common misconceptions about their structural integrity. We’re here to set the record straight by debunking common shipping container structural myths and giving you the facts.
Containers Will Last Forever
While shipping containers are built from durable Corten steel to withstand harsh ocean voyages, they are not immortal. Their lifespan depends on their environment and maintenance. Containers that are exposed to salt, moisture, and extreme weather without proper care will eventually rust and degrade. Regular inspections and protective coatings are essential to maximize their longevity and keep them structurally sound for years.
You Cannot Modify Containers
A popular myth suggests that cutting into a shipping container compromises its entire structure. While it’s true that modifications such as doors or windows remove structural components, fabricators compensate for these changes. We reinforce openings with steel framing to redistribute loads and maintain the container’s strength. This process allows us to create custom shipping containers for marketing activations or branded event spaces.
Containers Are Too Hot or Too Cold for Comfort
Another misconception is that shipping containers are unbearably hot in summer and freezing in winter, making them unsuitable for comfortable use. While external temperatures can affect containers due to their metal construction, proper insulation and ventilation easily solve this issue. Spray foam insulation, insulated panels, and HVAC systems can regulate interior temperatures, making containers comfortable year-round for living, working, or hosting events.
Shipping Containers Have No Load-Bearing Limitations
People often assume shipping containers can support immense weight without issue. However, they have load-bearing points. The strength of a container lies in its four corner posts, which transfer the weight to the foundation. You must align these posts to prevent structural failure when stacking containers. The roof and walls are not designed to bear high loads on their own.
Any Foundation Is Suitable for a Container
Placing a shipping container on a level surface is not enough to guarantee stability. The foundation is critical for a safe and durable structure. Without a proper foundation, a container can settle unevenly, leading to warped floors, misaligned doors, and structural stress. Common foundation options include concrete slabs, piers, and strip foundations.
The right choice depends on the soil conditions, local building codes, and your intended use of the structure. Don’t let these common shipping container structural myths stop you from enjoying their benefits.
