Glass beads, made of sodic tempered glass, are extremely resistant to impact and wear and tear.
They are used in shoot peening machines for surface cleaning of pieces, where it’s necessary to clean pieces without altering them.
Glass beads are chemically inert and don’t contain free lead and sulphides. |

Their resistance to high impact significantly decreases abrasive consumption and, consequently, draining costs.
They are particularly suitable for steel surface sand blasting and mould cleaning.
Creating very little dust, they can guarantee an excellent visibility inside the cabin and a uniform sandblasting of treated surfaces. |
