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.

    • Steel Color

      Steel is typically colored through a coating process. Surface inspection can ensure a smooth, even coverage of this coating and will also identify any surface defects that impact upon successful coating.

    • Steel Tinning

      Often used to prevent rust, this is the process of thinly coating steel sheets with tin to produce tinplate, which is primarily used to manufacture tin cans.

    • Steel Galvanized

      This process involves applying a protective zinc coating to steel to prevent rust. Inspection can ensure coating is successful, which protects the entire metal sheet from corrosion.
