Corten steel is a popular choice for landscaping and architectural applications due to its distinctive weathered appearance and durability. However, one of the biggest concerns with Corten steel is rust runoff, which can stain nearby surfaces such as concrete, stone, and decking. Understanding how to manage and prevent rust runoff ensures that you can enjoy the aesthetic benefits of Corten steel without unwanted staining. Here are some effective strategies to control and minimize rust runoff.
1. Pre-Weather the Corten Steel Before Installation
One of the most effective ways to reduce rust runoff is to pre-weather the steel before installing it in your landscape. This involves accelerating the natural oxidation process so that most of the rust forms and washes away before placement. To pre-weather Corten steel:
- Spray it with a solution of water and salt or vinegar to encourage rust formation.
- Allow the steel to undergo several wet-dry cycles over a few weeks.
- Rinse the steel periodically to remove loose rust particles before installation.
2. Professional Clear Powdercoat Sealing by National Planter Supply
At National Planter Supply, we offer professional clear powdercoat sealing to protect Corten steel from excessive rust runoff.

3. Proper Placement and Drainage Considerations
Strategic placement of Corten steel products can help minimize staining on adjacent surfaces. Consider the following placement strategies:
- Use Gravel Beds: Placing Corten steel above a gravel bed helps capture runoff and prevents staining on concrete or stone patios.
- Install a Drip Edge: Positioning a drip edge or flashing at the base of the steel can direct runoff away from sensitive areas.
- Slope Away from Stain-Prone Surfaces: Ensure that water drains away from pathways, driveways, or patios to prevent rust deposits.
