Company AST Metal performs a professional shot blasting metal products intended for painting and galvanizing.
The cleaning process removes rust, oxide, oil marks and old coating residue, creating an ideal surface for subsequent coats of paint or primer.

The process uses an abrasive steel shot (grit) with a controlled fraction. The flow is directed under high pressure, which ensures a uniform roughness without damaging the metal structure.
In addition, processing is performed according to the standards ISO 8501-1, ASTM D4417 и EN ISO 11124, which guarantees quality consistency.

Advantages of the AST Metal shot blasting line:

• Surface cleanliness standards SA 2½ - SA 3;

• Automatic cameras and tunnel systems;

• Abrasive filtration and recirculation;

• Roughness control (Ra-test);

• Preparation for painting and priming.

After machining, the parts are sent directly to the area paints (asmetal.com/painting) or welds (asmetal.com/welding), which speeds up the production process.
Detailed information on the methods can be found at ASTM.org, ISO.org and in the article Wikipedia: Airblasting.
