Sandblasting

   Sandblasting is a method applied to remove the oil, dirt, rust and corrosion on the metal due to rust and corrosion over time, and to extend the service life of the metal by painting. Sandblasting removes the rust and corrosion visible or micronized on the metal surface, but also reveals the essence of the metal.

   A metal that has just been sandblasted is at its most vulnerable to rust and corrosion. If the metal is left in a humid environment after sandblasting, it is observed that it is exposed to oxidation, which is manifested by color change within a few hours. For this reason, the sandblasted metal should be protected as soon as possible, and the contact of the metal with the air should be cut off by painting.
