As for why many people prefer industrial aluminum parts treated by sandblasting and oxidation, I think there are the following reasons:
1.Matte materials give people a more gentle and understated impression.
2. In some industrial fields, materials with reflective properties are not very suitable.
3. Sandblasted aluminum profiles can cover up extrusion marks (all extruded aluminum profiles will have extrusion marks).
4. Sandblasting can remove tiny burrs/protrusions on industrial aluminum profiles.
5. Sandblasting can also remove the oxide film on the surface of industrial aluminum profiles, so the sandblasting treatment process must be carried out before the oxidation process.
Overall, the choice of surface treatment method still depends on personal preference. Some people still prefer a bright oxidized surface, thinking it is clean and refreshing.

Neither of these two treatment methods has any impact on the subsequent anodizing treatment, and the oxide film still plays a role in wear resistance and corrosion resistance. So you can make a choice based on your needs.
