The popularity of Corten steel in architecture, landscaping and building outdoor structures boils down to its strength, durability and attractive aesthetic appeal. The protective patina that forms on Corten steel over time can improve the visual appearance of any steel structure and enable it to withstand exposure to the elements. However, as with all forms of steel, proper care and maintenance is essential if you want your Corten steel to maintain its durability and visual appeal in the long term. In this post, we take a closer look at how you can maintain your Corten steel for a long-lasting finish.
Understanding the Weathering Process of Corten Steel
For starters, it can be useful to gain a deeper understanding of how exactly Corten steel develops its patina. This process typically begins when the Corten steel is initially exposed to air and moisture. Unlike regular steel, which will corrode over time, the layer of rust that forms on Corten steel is a protective one. Its stability prevents further deterioration of the steel underneath and enables it to act as a barrier from moisture and air. The patina typically develops in stages, starting as a bright orange hue before darkening into a deep brown over time.
Proper Maintenance of Corten Steel for a Long-Lasting Finish
Given the unique quality and properties of Corten steel, proper care must be taken to ensure that the patina develops evenly and that the steel remains structurally sound over time. Some best practices you can follow to ensure that your Corten steel remains well-maintained include:
- Ensuring Proper Exposure: In order to allow for even patina formation, it is important that your Corten steel is properly exposed to air and moisture. You should avoid water pooling and prolonged dampness as these can lead to uneven formation of the patina.
- Avoiding Aggressive Cleaners: Unlike regular steel, you should also avoid aggressive cleaners and cleaning tools when cleaning Corten steel, as these can cause damage to the patina. Opt for mild detergents and soft brushes instead when cleaning Corten steel and focus on gently removing stains, dirt and debris without damaging the patina that has already built up.
- Inspecting Regularly: At the same time, you should inspect your Corten steel regularly to check for excessive corrosion, structural weaknesses, and unwanted or accidental damage. Addressing these issues early can help to prevent them from becoming too severe.
