How Can You Address Potential Rust or Corrosion Issues with Shipping Containers?
Shipping containers have become a ubiquitous solution for storage and transport needs across various industries. Whether you’re repurposing a shipping container for a tiny home, a pop-up shop, or simply using it for storage, one concern that often creeps into the minds of users is rust and corrosion. Having spent months searching for the perfect shipping container for my art studio, I faced the dreaded reality of rust and let me tell you, it was a journey filled with lessons! So, how can you address potential rust or corrosion issues with shipping containers? Let’s dive in.
Understanding the Rust Problem
Before I get into the nitty-gritty of preventing and treating rust, let’s talk about what causes it. Shipping containers are primarily made of steel, which, as we know, is prone to rust when exposed to moisture and oxygen. This is especially true if the container is not properly sealed and maintained.
During my container search, I found a seemingly perfect unit; however, upon closer inspection, I noticed spots of rust developing in the corners. My heart sank as an artist, I worry about the longevity of everything I invest in. But I quickly learned that rust doesn’t have to spell disaster; it just requires a proactive approach.
Proactive Measures for Prevention
1. Choose the Right Location
When positioning your shipping container, consider the environment it will be in. Avoid placing it in low-lying areas where water can accumulate. Instead, opt for higher ground or gravel-based foundations that allow for drainage. Personally, I opted for a slightly elevated platform after watching water puddle near a friend’s container, and it made a world of difference.
2. Regular Inspections
Just like I periodically check my art supplies for quality, regularly inspecting your shipping container is key. Look for signs of rust early! A quick monthly inspection can save you from larger issues down the line. When I established my studio, I adopted a routine of checking underneath and around the edges for any tiny rust spots that might develop.
3. Painting and Coating
Applying a protective coating can significantly reduce rust risk. Using a high-quality marine-grade paint can act as a barrier against moisture. I remember spending a rainy afternoon tackling this project, applying a layer of rust-inhibiting primer first, followed by a vibrant final coat. Not only did it protect against rust, but it also added a personal touch to my studio!
4. Keep It Dry
Water is the enemy of steel. Ensure that the container’s ventilation is adequate. I installed a couple of vents on my shipping container, which helped reduce humidity inside. You might also consider placing moisture-absorbing materials inside, like silica gel packs, especially if you live in an area with high humidity.
Addressing Existing Rust Issues
Even with the best preventative measures, rust can still occur. Here’s how to tackle it effectively:
1. Assess the Damage
Conduct a thorough assessment to determine the extent of the rust damage. For small areas, you might be in luck, but larger patches might require more serious action. One weekend, I found some rust on the edge of my container door a small patch that was easily manageable, but I knew I had to address it before it spread.
2. Scrape and Sand
Using a metal brush or sandpaper, you can remove the rust. For my container, I used an angle grinder with a flap disc, and it was both cathartic and effective! Make sure to wear protective gear, as rust particles can fly around during the process.
3. Apply Rust Treatment
After sanding down to bare metal, apply a rust converter to neutralize remaining rust particles. I purchased a well-reviewed rust converter from a local hardware store and applied it liberally to the affected areas. It’s essentially a primer that prevents future rust development.
4. Repaint and Seal
Once the rust has been treated, repaint the area with a rust-inhibiting paint. For the final touch, consider applying a sealant to ensure maximum protection. I had fun choosing fun colors for my container, and it felt rewarding to know the new paint was doing a double duty of protecting my space and expressing my creativity!
Final Thoughts

Addressing potential rust and corrosion issues doesn’t have to be daunting. With regular maintenance, strategic placement, and timely intervention, your shipping container can stand the test of time. If you ever find yourself in a situation like mine, remember that every challenge is an opportunity for creativity and learning. Those experiences will only enhance the value of whatever you store or create inside. So get out there and give your shipping container the love it deserves your future self will thank you!
