The image below shows the result of metal sandblasting on the metal surface of a heating furnace in a petrochemical production facility. Epoxy zinc-rich primer is used as the base coat, and the metal surface treatment is required to reach Sa2.5 grade. Has the sandblasting result been achieved below?
