SANDBLASTING

The term sandblasting refers to a mechanical process that allows the surface of a metal product to be cleaned of residues and corrosive encrustations, obtaining a finish that ensures a suitable and adequate hold for subsequent painting treatments and application of protective coatings.

In general, sandblasting is carried out before the completion of a cycle of work on the parts with the painting treatment. The process removes and eliminates impurities and corrosive slags such as paint, rust scale, oxides and calamine. 

Removal is achieved by means of a sand and air jet blasted at high speed and under very high pressure. Alternatively, abrasive material can be blasted by rotating turbines.

Sandblasting metals restores the appearence of the object to what it was before the surface was altered and modified by oxidation and surface corrosion.

Our systems are suitable for any type of material, size and weight (up to 100 tonnes); for the surface treatment, we use metallic, spherical and cylindrical grit, garnet, glass microspheres, corundum and sand.
