Get Corrosion Under Control with Lakeside Painting

What is Corrosion?

When chemical reactions occur between a metal and environmental factors, the metal starts to deteriorate. This process is known as corrosion. The type of metal, as well as the surrounding environment, play a role in determining the type and rate of corrosion.

The Worldwide Corrosion Authority estimated that in 1998, the direct costs of corrosion were $276 billion. A decade later, it is safe to assume that those figures have increased exponentially.

While all metals have the potential to corrode, those which combine iron and other alloys – like stainless steel – corrode more slowly and thus are used more frequently. A group of metals that is highly resistant to corrosion is a class known as noble metals. Noble metals are unreactive and don’t combine with other elements to form compounds – characteristics which diminish their rate of corrosion. Gold, silver, platinum, palladium, and copper are all examples of noble metals.

Types of Corrosion

There are many different types of corrosion, and they occur for many different reasons. Some of the more commonly seen types of corrosion are detailed below.

1)      General Attack Corrosion is caused by chemical reactions and attacks the entire surface of the metal. Since general attack corrosion is a predictable issue, steps can be taken to manage it.

2)      Localized Corrosion comes in three forms: pitting, crevice corrosion, and filiform corrosion. Filiform corrosion occurs whenever moisture gets under a coating of paint.

3)      Galvanic Corrosion occurs whenever two distinct metals are located in the same liquid electrolyte solute. One metal’s molecules gravitate toward the other metal, causing corrosion in only one of the metals.

4)      Environmental Cracking is the result of harsh environment conditions, which can sometimes cause the metal to crack or become weak and brittle.

How We Can Help

As previously mentioned, while corrosion cannot be eliminated altogether, certain types of corrosion, like general attack corrosion, are predictable issues. As such, certain steps and measures can be taken to reduce the rate of corrosion.

Painting

A simple and affordable way to control the rate of corrosion is by painting. Paint serves as a protective layer between the metal and the surrounding environment.

However, to effectively offset corrosion, the metal surface must be properly prepared. Filiform corrosion looks like a series of small worms and occurs whenever metal surfaces are not properly treated before painting.

The painting contractors at Lakeside Painting can help you get corrosion under control by applying a sealing coat of paint to both interior and exterior commercial and industrial structures.

Specifically, electrostatic spray painting is a method of painting devised solely for metal objects. The targeted surface is given a negative charge by attaching a negative electrode to it. Oppositely charged paint is then sprayed on the surface. The opposing charges result in a magnetic attraction that pulls paint particles toward the surface of the object. Because of its effectiveness and relatively light cleanup, electrostatic paint application is rather popular.

Adequate Cleaning

According to the FAA, foreign materials which adhere to metal surfaces are among the controllable factors that affect the onset and spread of corrosive attack. Foreign materials include things such as dust, oil, grease, and salt.

Lakeside’s professional commercial painters offer a variety of cleaning and abrasive blasting services. In addition to high-pressure washers used to clean building exteriors, dry ice blasting and sponge blasting are among our preferred methods for removing paint, contaminants, and foreign materials.

Corrosion can be a real problem. If left untreated, it has the potential of destroying practically any surface. While protecting yourself and your facilities against corrosion may seem like an unnecessary upfront cost, it will save you a lot of money (and headache) in the future. Call us now! Serving Wisconsin and select cities throughout the Midwest, the professionals at Lakeside are ready to help you tackle any project and get your corrosion under control.
