Are Shipping Containers Rustproof?
Get a quoteDo Shipping Containers Resist Rust Over Time?
Key Takeaways
- Shipping containers are not entirely rustproof but are made from corten steel which has superior rust resistance.
- Corten steel forms a protective oxide layer that slows down the rusting process and improves the container's durability.
- Regular maintenance and application of protective coatings can significantly improve rust resistance.
- Conexwest provides a range of shipping containers which can be customized.
Factors Affecting Rust Resistance In Shipping Containers
1. Exposure to Moisture and Humidity
Shipping containers are often subjected to high levels of moisture, especially during transit across oceans or in humid climates. Prolonged exposure to moisture can accelerate the rusting process.
2. Quality of Container Materials
Many containers are made from corten steel, which develops a protective oxide layer that slows down corrosion. However, if this layer is compromised due to scratches, dents, or damage, the container becomes more susceptible to rust. Containers made from lower-quality steel may not provide the same level of protection.
3. Environmental Conditions
The following factors can contribute to accelerated rust formation:
- Salt air from coastal regions
- Airborne pollutants from industrial areas
- Standing water on the container's surface

Best Practices For Improving Rust Resistance In Shipping Containers
Painting your container is one of the easiest methods to improve its rust resistance.
- Use Quality Materials: Opt for containers made from corten steel, which is more durable against corrosion compared to standard carbon steel.
- Regular Inspections and Maintenance: Conduct routine inspections to identify early signs of rust or damage. Pay special attention to:
- Corners and edges where water may collect
- Dents or scratches that may expose the steel
- Apply Protective Coatings: Use marine-grade paints and rust inhibitors to create a barrier against moisture. Consider using zinc-aluminum coatings for improved protection, as they provide cathodic protection against rust.
- Maintain Proper Ventilation: Adequate ventilation reduces humidity levels. Install ventilation solutions such as vents, whirly birds, or moisture absorbers to promote airflow.
- Control Moisture Exposure: Minimize exposure to moisture by:
- Elevating the container on a platform to prevent contact with groundwater and snow
- Avoiding standing water around the base of the container, which can accelerate rusting
- Using tarps or covers during wet weather to shield the container from rain or snow
- Maintain Cleanliness: Regularly clean the container to remove dirt, salt, and debris that can trap moisture against the steel. Washing with fresh water helps eliminate contaminants that contribute to rust formation.
- Implement Insulation: Proper insulation can help maintain a stable internal environment and minimize moisture accumulation.
- Address Rust Promptly: If rust is detected, treat it immediately. Small patches can be managed by:
- Wire brushing and sanding the affected areas
- Applying vinegar to neutralize rust before repainting with marine-grade paint
Rust-resistant shipping containers are suitable for use in high-humidity conditions.

Frequently Asked Questions (FAQs)
- Are all shipping containers made of corten steel?
No, not all shipping containers are made of corten steel.
- What causes rust on shipping containers?
Rust is caused by the combination of moisture, oxygen, and steel. Exposure to salt air, standing water, dents, and physical damage to the paint coating can accelerate the rusting process.
- How often should I inspect my container for rust?
It's recommended to inspect your container at least once every six months. However, if the container is exposed to harsh environmental conditions, more frequent inspections may be necessary.
- Can rustproof coatings be applied to old containers?
Yes, rustproof coatings can be applied to old containers to improve their rust resistance. Before applying the coating, the container should be thoroughly cleaned and any existing rust addressed.
- Does Conexwest have rental options for shipping containers?
Yes, we have flexible rental options on a 4-week basis. You can then extend your rental duration for as long as you like.
