Shot Blasting vs Grit Blasting: What Is the Difference?

Grit Blasting

Shot blasting and grit blasting are both abrasive blasting processes used to clean and prepare metal surfaces before coating, but they use different media and produce different results. Shot blasting uses round, spherical particles (steel shot, glass bead) that peen the surface, while grit blasting uses angular, sharp-edged particles (steel grit, aluminium oxide, garnet) that […]

What Is Shot Blasting and Why Is It Important Before Coating?

Shot Blasting

Shot blasting is a surface preparation process that fires small steel shot or grit particles at high velocity against a metal surface to remove rust, mill scale, old coatings and contaminants. It is the most effective way to prepare metal before powder coating, creating a clean, roughened surface profile that allows the coating to bond […]
