Maintaining Your Used Shipping Container for Longevity

Just like a well-constructed roof, a used shipping container can offer long-term protection and reliable storage—if it's properly maintained. Both structures are built with durability in mind, engineered to withstand tough conditions while safeguarding what's inside. However, anything left to face the elements year after year—sun, wind, rain, snow—will inevitably show signs of wear and tear. The key to extending the life of a decommissioned container lies in consistent care and preventive maintenance.

A Structural Comparison: Roofs vs. Shipping Containers

Roofs and shipping containers share more in common than you might think. They’re both designed to provide shelter and withstand the forces of nature. According to This Old House, “a roof can last between 25 to 50 years,” depending on materials, installation quality, and maintenance. Similarly, shipping containers—especially when repurposed for storage, offices, or living spaces—can also serve their purpose for decades when maintained properly.

To maximize the lifespan of your used shipping container, consistent maintenance is non-negotiable. Here are key areas to focus on:

• Rust Prevention: While rust is generally just a chemical reaction and typically a superficial aesthetic factor. Rust can be an enemy of steel containers if not addressed. Regular inspections should target common rust-prone areas—such as the roof, corners, and door frames. Clean any rust spots and apply rust-resistant paint or sealants promptly.
• Ventilation: Good airflow is critical, especially in humid or rainy environments. Poor ventilation can lead to condensation build-up, which accelerates corrosion and can damage items stored inside. If due to your geographic area condensation is a issue, Eveon does suggest proper ventilation which can be addressed post purchase with a local vendor or handy man.
• Sealing and Waterproofing: Inspect and reseal any worn or cracked joints, seams, or door gaskets. Waterproof coatings can provide an additional layer of protection, particularly on the roof and base.
• Foundation and Positioning: Ensure the container is placed on a level, well-drained surface to prevent water pooling underneath. Raised foundations, such as concrete piers or gravel beds, help reduce moisture contact and improve ventilation.
• Lubrication: To keep shipping container doors operating smoothly, it's essential to regularly lubricate the hinges and locking mechanisms. This helps prevent rust, reduces friction, and makes it easier to open and close the doors. Applying a high-quality lubricant like WD-40, all-weather lubrication, or a specialized shipping container lubricant can make a big difference.

Educating Users on Long-Term Container Care

For anyone investing in a used shipping container—whether for business, residential, or creative purposes—understanding its upkeep is crucial. A little preventive effort goes a long way. Teaching container owners to recognize early signs of wear, perform routine checks, and apply protective measures not only preserves structural integrity but also protects their investment.

Trusted since the mid 50’s to securely transport goods globally, Eveon Containers belief and mission is to give containers another life on land. Jessica Mashek, Eveon’s Customer Care Lead quickly adds, “Shipping containers are more durable and secure than most prefab modular structures in the market these days. If properly cared for a Corten steel box can serve as a smart, functional and sustainable solution for years to come.”

Protect Your Investment

With the right approach, a used shipping container can offer the same peace of mind and protective strength as a well-maintained roof. They’re built tough—but it’s the attention to detail in maintenance that truly ensures their longevity. Treat your container like a building component, not just a box—and it will continue to serve you well for years to come.
