If you work in an industrial setting, you’ve likely heard of zinc plating and hot dip galvanizing. But do you know the differences between the two processes? Knowing the difference is essential for protecting your assets from corrosion. Let’s take a look at how these two processes differ.
What is Zinc Plating?
Zinc plating is a relatively simple process that involves coating the surface of a steel or iron substrate with a thin layer of zinc. The process involves electroplating, which means that electricity is used to coat the substrate with zinc. This creates a protective barrier on metal surfaces, making them less susceptible to corrosion. Zinc plating can be found in many everyday items, such as automotive parts, computer components, and more.
Zinc plating is typically used for items that require only light resistance to corrosion due to its thin layer of protection. It’s also economical since it doesn’t require as much material or labour as other methods. However, it does not provide long-term protection against harsh environments because its layer of protection can eventually degrade over time.
Hot Dip Galvanizing
Hot dip galvanizing is a process in which steel or iron substrates are coated with molten zinc in order to provide superior protection against corrosion. Unlike zinc plating, hot dip galvanization provides long-term protection since the molten zinc bonds directly to the substrate, creating an extremely durable bond that will last for years without degrading over time. This type of coating is often used in outdoor applications such as bridges, buildings, fences and more, where superior protection against corrosion is required. Hot dip galvanizing also requires more material and labour than zinc plating but produces much better results when it comes to providing long-term protection against harsh environments such as salt water or acidic soils.
Difference Between Zinc Plating and Hot Dip Galvanizing
- Zinc plating is a process in which a thin layer of zinc is applied to a metal surface in order to protect it from corrosion.
- Hot dip galvanizing is a process in which a metal surface is coated with a layer of zinc.
- Zinc plating is typically used on smaller metal objects, such as hardware or automotive parts.
- Hot dip galvanizing is typically used on larger metal objects; such as fences or pipes.
- Zinc plating is less expensive than hot dip galvanizing.
- Hot dip galvanizing provides a more durable finish than zinc plating.
Conclusion:
When choosing between zinc plating and hot dip galvanizing for your project, it’s important to consider your needs and budget before making a decision. For short-term projects that require light resistance to corrosion, zinc plating may be your best bet since it requires less material and labour than hot dip galvanization and offers adequate protection against most conditions. However, suppose you need superior long-term protection from harsh environmental conditions such as salt water or acidic soils. In that case, hot dip galvanization should be your go-to choice due to its superior level of durability and longevity compared to other coating methods like zinc plating or painting. Ultimately, selecting the right coating method will ensure that your project has maximum longevity and minimal maintenance costs down the line!
