sandblasting is the essential industrial process used for surface preparation and protection. Sandblasting, also known as abrasive blasting, involves propelling abrasive materials like sand or grit at high speeds onto a surface to remove rust, paint, or contaminants, creating a clean and roughened texture for improved adhesion of coatings. Metallizing, on the other hand, is a technique where a thin layer of metal, often zinc or aluminum, is sprayed onto a surface using a thermal spray process. This creates a protective coating that shields against corrosion, oxidation, and wear. Metallizing is commonly used in industries like construction, automotive, and aerospace to extend the lifespan of metal structures and components.
