Powder coating involves several steps:

​

1. Preparation: Clean the item thoroughly to remove any oil, dirt, or rust. This could include sandblasting to ensure a smooth surface.
    

2. Application: Apply an electrostatically charged powder to the items surface using a spray gun. The charge helps the powder adhere evenly.
    

3. Curing: Place the coated item in an oven to cure. The heat melts the powder, forming a smooth, durable finish as it cools.
    

This process provides a tough, corrosion-resistant coating that can be customized in various colors.
