When you hear the word corrosion, what comes to mind? Perhaps images of old, rusted metal. But corrosion is not just an aesthetic issue — it’s a serious threat that can lead to costly repairs and even equipment failure. Corrosion is an insidious process that causes metals to break down and corrode over time. It occurs when moisture or another element attacks the surface of a metal and begins to destroy it. To prevent corrosion, you need corrosion-resistant coating, which acts as an invisible shield against moisture and other harmful elements. When considering the type of finish for your iron or steel project, take into account its usage and how much exposure it will have to moisture. If any part of your project will be exposed to rain or humidity, we recommend selecting a paint with built-on corrosion resistance properties.
Corrosion resistant coating is a protective layer that resists rust and corrosion. This coating is available in a wide variety of types and formulations, which provide differing levels of protection against corrosion. The primary types of corrosion resistant coating are: - Zinc coating - Zinc is the most commonly used coating for corrosion resistance. Zinc-based coatings are extremely effective and are commonly used in marine environments. - Aluminum coating - Aluminum-based coatings are extremely effective in marine and high-humidity environments. - Stainless steel coating - Stainless steel-based coatings are extremely effective in marine, high-humidity and high-corrosion environments. However, stainless steel-based coatings are slightly less effective in marine environments because salt can erode the coating. - Nickel coating - Nickel-based coatings are effective in marine and high-humidity environments.
Equipment corrosion can result in downtime and costly repairs, as well as pose a safety hazard for your employees. - Corrosion can damage equipment and cause production delays, which can be costly. If corrosion is damaging a crucial piece of equipment, it may be necessary to shut down production while the piece is repaired or replaced, which can negatively impact your bottom line. - The average cost of corrosion in the United States is $37 billion annually. That figure includes the cost of lost product, preventable accidents and equipment failures that are due to corrosion. - The presence of corrosion can pose a safety risk to your employees. Corroded equipment can be more prone to failure, which can lead to injuries or even death if the equipment is operated incorrectly.
When applying a corrosion resistant coating, there are a few things to keep in mind. First, make sure you are applying it to the correct surface. Some coatings are meant for interior use only. While other coatings can be used for both interior and exterior applications. Always follow the manufacturer’s instructions for application. While each product has its own specific instructions, here are some general tips on applying corrosion resistant coating. - Make sure the surface is clean before applying the coating. Use a solvent to remove any grease or oil. Sand the surface if it’s rough. - Make sure the surface is dry. Use a blower or a wet rag to remove as much moisture as possible. - Apply the coating evenly over the surface and let it dry completely before using it.
There are many considerations to take into account when choosing a coating for your iron or steel project. Be sure to take into account the environment the project will be used in and the expected lifespan of the project. If you are unsure how the coating will hold up, be sure to check with the manufacturer to see how it will perform in your specific environment and for your specific application. When it comes to corrosion resistance, one size definitely does not fit all.
