The blasting process and the various types of abrasives

The sandblasting process is a mechanical technique for the controlled cleaning of a surface, usually metallic. It is made by erosion thanks to the abrasion generated by propelling metal shots or grit with compressed air lances.




Another method uses wheel blasting machines. The sandblasting process, in addition to allowing the surface of a metal product to be cleaned from residues and corrosive scales, can also be used to obtain a particular surface roughness for subsequent coating or painting processes. In the case of shot-peening, on the other hand, it’s used to add strength and reduce the stress profile of special components.



The abrasives that can be used for blasting have different characteristics and are chosen based on the work to be carried out.

The most used are:


The W Abrasives brand is part of the Winoa group which was founded in 1961 and is a leader in the production of high carbon steel shot.

The main applications of shot blasting processes are: sandblasting, deburring, descaling, shot-peening, surface preparation and sawing of granite.

In addition to steel shots and grits, the product range of W Abrasives also includes: glass microspheres and grits, cut wire, corundum and garnet.

Our technicians and salesmen can study together with customers the best solution for their shot-blasting process.
