Despite steel’s well-known strength and versatility, it still has a major vulnerability: it’s prone to rust. If you’re looking for information on how to keep steel fabrication works looking and performing their best, here’re some simple but effective ways:
Choose corrosion-resistant materials
One of the most effective ways to prevent rust is to select the appropriate type of steel. Alloy steels, such as stainless steel, are specifically designed to resist corrosion due to their chromium content. Chromium forms a thin protective layer on the steel’s surface, preventing oxygen and moisture from causing oxidation. Another effective option is galvanised steel, which is coated with zinc. The zinc coating serves as a protective barrier, corroding in place of the steel and thereby preserving its integrity.
Add protective coatings
Applying protective coatings is an effective way to shield steel from environmental factors such as oxygen and moisture. There are several types of coatings that can be used:
- Paint: High-quality anti-corrosion paints provide a durable layer of protection. These paints are specifically formulated to prevent rust. However, proper application is crucial to ensure all surfaces are covered.
- Powder Coating: Powder coating involves applying a dry powder to the steel and curing it under heat to create a hard, protective film. This method provides excellent resistance to corrosion.
- Epoxy Coating: Epoxy coatings are ideal for industrial applications where the steel may be exposed to harsh chemicals. They provide a tough, chemical-resistant barrier.
Consider cathodic protection
Cathodic protection is a specialised method used to prevent rust in certain environments, such as underground or submerged steel structures. This process involves attaching a more reactive metal, such as zinc or magnesium, to the steel. The reactive metal acts as a sacrificial anode, corroding in place of the steel and thereby protecting it.
Control the environment
Controlling environmental exposure is crucial for rust prevention. Steel should be stored and fabricated in dry, well-ventilated areas to minimise exposure to moisture. In coastal environments, where salt in the air accelerates corrosion, additional protective measures such as marine-grade coatings are recommended.
Regular maintenance and inspection
Even with preventive measures in place, regular maintenance and inspections are essential to ensure long-term protection against rust. Routine inspections can identify early signs of rust. Practices such as cleaning, repainting, and recoating can significantly extend the life of steel structures.
