Sand Blasting glass beads are used in cleaning the surface of all kind of metal products.

The glass beads made of the soda-lime silica glass has the good chemical stability, certain mechanical intensity and hardness, so it used as polishing and grinding material .Do not pollute the processing metal.,accelerate the cleaning up, make the processing material to restore originally clean, smooth.

Glass bead for sand blasting media with their hardness and spherical form can remove impurities and metal oxides without damaging the treated surface.

Glass does not react chemically with other material so that the micro-beads do not create any corrosion on the treated surfaces with no deposits of foreign substances.
