Sand Blasting

Sand blasting is a surface preparation technique that uses abrasive materials propelled at high velocity to remove rust, paint, or contaminants from a surface. It is commonly used in cleaning and preparation processes.

Shot Blasting

Shot blasting is a similar process to sand blasting, but it uses small metallic particles (shots) instead of abrasive sand. It is often used for cleaning, deburring, and preparing surfaces for coatings.


Anodizing is an electrochemical process that enhances the corrosion resistance and appearance of metals like aluminum. It creates a protective oxide layer on the metal’s surface, which can be colored for decorative purposes.
