Sand Blasting Abrasive Steel Shot Steel Grit For Steel Surface Treatment S780

 

Steel grit Surface preparation
Surface preparation is as a series of operations including cleaning and physical modification of a surface. Steel shot and grit are used in surface preparation process for cleaning metal surfaces which are covered with mill scale, dirt, rust, or paint coatings and for physically modifying the metal surface such as creating roughness for better application of paint and coating.

The steel shots are generally employed in shot blasting machines.
