The biggest enemy of custom steel fabrication is steel corrosion. It damages structures made from steel and results in costly maintenance! Here’s how to stop corrosion in its tracks.
What is Steel Corrosion?
Corrosion or rust occurs when the metal starts to disintegrate as a result of the environment, and usually happens when there is moisture present. Moisture acts as an oxidising agent and exposure to a metallic surface can start the corrosion process. Metal rusts when it reacts with substances like hydrogen and oxygen.
Here Are a Few Tips to Prevent Steel Corrosion
- Choose metals that are fairly resistant to rust like stainless steel and aluminium.
- Keep the area surrounding the metal surface dry.
- Use products and dry agents that will lock in moisture, acting as a barrier to prevent wet substances from penetrating your metal.
- Use layers of backfill when pipes are placed underground.
Sacrificed Metals
Metals like zinc and magnesium can act like armour and protect the steel from corrosion. When these metals are placed in direct contact and cover the steel, they will corrode first and be sacrificed so that the steel inside remains rust-free.
Coatings Are Very Effective
There are a number of coatings that will help protect your metal. These include:
- Paint – this cost-effective solution works by blocking moisture and other corrosive substances by stopping the electrochemical charge from being transferred directly to the metal.
- Carbon fibre coating – the metal is covered by sheets of carbon fibre to protect and strengthen the quality of the material, thereby making it less vulnerable to unexpected leaks and cracks.
- Powder coating – is highly effective, so when the powder is applied to the surface of a metal, heated and smoothed, it creates a protective rust resistant barrier. Polyester, acrylic, urethane and nylon are all examples of this type of coating.
- Epoxy coatings – can withstand industrial settings and take on different finishes including gloss and colours. Spraying is recommended for this type of application.
Control External Environments
Lower the risk of your metal being exposed to seawater or rain. A more advanced method is by controlling and monitoring the levels of oxygen, sulphur and chlorine present around the metal.
