Steel Fence Maintenance: Rust Prevention Techniques

Steel Fence Maintenance Rust Prevention TechniquesSteel fences are highly versatile and are a popular option amongst homeowners due to their durability and low maintenance requirements. However, just because steel fences are low maintenance does not mean that they completely don’t need to be maintained. Steel fences still require regular maintenance to prevent them from rusting or experiencing structural failures. In this post, we take a closer look at how you can maintain your steel fences by preventing rust from forming on them.

Rust Prevention

While steel is generally one of the strongest and most durable building materials in the world, it is susceptible to rust, which can form when the right conditions are present. Generally, rust forms in the presence of moisture and oxygen, which causes a chemical reaction to occur on the top layer of the steel that converts iron into iron oxide, which is what gives rust its signature colour and appearance. Warmer temperatures, such as the ones experienced in Australian summers, can also act as a catalyst, speeding up this process and causing more rust to form.

Not only is rust visually unappealing, but it can also affect the lifespan of your steel fences. As such, preventing rust from forming is extremely important if you want to maximise the longevity of your steel fences. Some of the most common rust prevention techniques include:

Rust-Resistant Coating

Rust-resistant coatings or corrosion-resistant coatings can come in a variety of different forms, including sprays or liquids that you can apply on the surface of your steel. These coatings prevent oxygen from coming into contact with the underlying steel, preventing the chemical reaction that causes rust from occurring. If you opt to apply such coatings on your steel fences, ensure that you clean your steel properly before application to help it retain the coating more efficiently.


If you are using regular steel for your fences, galvanising it can help to make it resistant to rust and corrosion. Galvanisation is a process where the surface of the steel is covered with a layer of zinc, which is a non-reactive metal that does not form rust. This process is most commonly done through a process known as hot-dip galvanisation, where the steel is dipped into molten zinc.


As an alternative to rust-resistant coatings, painting is also a great way to protect your steel fences from rust. Painting your steel fences can also give your fences a new look, helping to improve their aesthetic appeal. If you opt to paint your steel fences, ensure that you clean them properly beforehand and touch up any peeled or chipped paint periodically.
