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 high quality defect free 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 suit different applications or to add color or extra corrosion resistance.

    • Steel Color
      Color

      Steel is typically color-coated in a continuous process line where paint is applied by rollers which is subsequently cured in ovens before re-coiling. Surface inspection can ensure a smooth, coverage of this coating.
