How to Protect My Fences? Oxidation, Corrosion and Rust Are Not the Same Thing
Do you know how to protect your metal fences from oxidation, corrosion and rust? To solve these problems effectively, it is necessary, first of all, to understand the differences between the three corrosive processes. Contrary to what many people think, oxidation, corrosion and rust are not the same thing. And the correct treatment of each phase helps to prevent the premature loss of the most diverse metallic structures.
Proper surface treatment will help to increase the life of both fences and other metallic structures, such as gates, windows, piping in general and even equipment and machinery. So read on to better understand.
Oxidation, Corrosion or Rust?
Oxidation is the beginning of the metal’s degradation process and must be treated as soon as it appears, so as not to give rise to corrosion and rust. Oxidation in metals begins when an unprotected surface (unpainted, for example, or damaged by scratches or impacts) comes into direct contact with air, water vapor or water.
If oxidation is not prevented, then the corrosion process begins. In this case, there is greater detachment of the metal, which is increasingly exposed to damage caused by contact with the atmosphere. The material starts to change color and spots, stains and deposits appear on the surface. In the case of painted structures, but with the protective layer damaged by impact or scratches, the problem tends to spread over the paint, and the coating starts to bulge and crack.
Finally, when they are already oxidized and corroded, ferrous metals – such as steel and iron – begin to generate iron hydroxide, the reddish layer known as rust. Rust further compromises the strength of the metal and, depending on its magnitude, makes recovery unfeasible.
How to Recover a Metal Fence?
In all three cases, oxidation, corrosion or rust, it is necessary to remove the affected part by sanding the metal (or using a chemical product for this purpose) and then protecting the surface again. This can be done with paint or a galvanizing process to prevent the structure from coming into contact with air.
Depending on the structure, if it is very rusty, for example, recovery becomes impossible. If rust is only on the surface of the metal in question, it is still possible.
How Can I Avoid Damage to Metal Fencing?
Preventive maintenance, as well as corrective maintenance, are essential to avoid damage to metal fencing for consumers. It is necessary to identify surface flaws as soon as possible and then intervene, removing oxidation, corrosion or rust in time. Then, just apply a protective layer over the surfaces to keep the metal structure in good condition for much longer.
And if you are thinking of installing a metal fence, whether it is in your home or business, you can choose materials that have already gone through the galvanizing process. Basically, this is a technique that consists of applying a protective layer of Zinc to a steel or iron surface. It prevents the corrosion of fences and thus contributes to their quality.
