Corrosion can affect various materials, causing deterioration and damage. If left untreated, corrosion can be visually unappealing at best or an expensive safety hazard at worst. We’ll delve into the causes and types of corrosion, as well as preventative measures to help you better understand and combat the steel deterioration process.
Corrosion is the gradual deterioration of materials, caused by chemical reactions with the environment. It is a natural process and is most associated with metals, but it can also affect other materials like ceramics and plastics. The corrosion process happens when a material reacts with substances such as oxygen, water, acids, or salts, leading to the breakdown of its structure.
Several factors contribute to corrosion. The primary factors include:
There are many types of corrosion, each with distinct characteristics and causes. The most common types include:
Uniform corrosion is the most common type; fortunately, it is also among the easiest types of corrosion to prevent.
Preventive measures can help minimise the risk and impact of corrosion. Some effective strategies include:
There is still hope if your steel has started to corrode. A surface-cleaning technique such as shot blasting can remove any existing rust off the steel. While shot blasting on its own won’t prevent rust from building up again, it is a crucial step before galvanizing to make the process more effective.
If your steel is very rusty, it may not be possible to recover. In the future, book in with a reputable galvanizing company as soon as possible after steel fabrication.
By understanding the causes and types of corrosion, as well as implementing preventive measures, it is possible to minimise its impact.
