Shot blasting process has become an integral part of steel structure and metal building industry. It removes all rush, mill scale and corrosion, thus eliminating moisture which is almost always entrapped beneath these corrosive products. It also provides ideal surface finish (SA2.5) for securing a bond between the steel surface and coat.

The protective paint systems usually consist of primer, undercoat (s) and finish coats
