3.Steel grit application

(1)Sandblasting for Shipbuilding
 With grit blasting, oxygenated surface of ship hull is descaled,then improved the coating quality.
(2)Castings Surface Pre-treatment
 Steel grit can also be used for surface pre-treatment,cleaning and descaling for casting parts.
(3)Bridge and Steel Construction
 Pre-treatment and descaling for metal surface,increasing coating quality and antisepsis ability.
(4)Cleaning 
 Blast cleaning, forging, casting deoxidization, cleaning H section steel, stainless steel structure.
(5)Derusting 
 Casting rust, forgings, rust removing, iron removal, steel derusting, h-steel derusting, steel structure derusting.
(6)Reinforcement
Heat treatment part shot shot strengthening, gear shot strengthening.
