Abrasive Blasting (Sandblasting)

Abrasive blasting is one of the most critical surface preparation steps in the metal finishing process. By propelling various abrasive media at high velocity, this process effectively removes mill scale, corrosion, weld spatter, and any residual coating from prior work.

The selection of blast media, whether steel shot for aggressive removal, glass bead for a gentler finish, or aluminum oxide for precision work, depends on the substrate material and desired final appearance. Industry standards such as SSPC and NACE define specific surface profile requirements to ensure proper adhesion of subsequent coatings.

Proper blasting technique directly impacts the success of your metal finishing project, as inadequate surface preparation is a leading cause of coating failure in the field.
