Coating

Steel Coating
Steel is often coated to provide qualities such as rust resistance or to add cosmetic value. Flaws in the coating can undermine any protective qualities and affect the appearance of the metal.

To ensure effective coating, it is important to have a smooth steel surface prior to the process. A high-precision inspection system can support this, and can also monitor the coating itself.

Steel is commonly galvanized if there is a possibility of future corrosion. Other coatings may be applied to add different properties to the metal, or to change the color of the steel.
