Metal Sandblasting

At the base of a well done job

Sandblasting is a process that allows us to uniform the surface of metals and is particularly suitable and recommended for preparing metals for subsequent processing such as painting.

Traces of rust and oxidation, old paint residues, and other substances can be found on metal surfaces. All these particles, if not removed, can nullify any protective treatment or may compromise the duration of the paint over time.

SPECIALIZED EQUIPMENT

Our company has two large booths for metal blasting, respectively of 20 x 6 x 8 meters and of 20 x 6 x 6.5 meters, equipped with the most modern dust removal system. Through our tested sandblasting cycle, with metallic grit or sand of different sizes depending on the material to be treated, we carry out the cleaning of metals damaged by oxidation, rust, incrustations or residues of previous varnishes.

CUSTOMIZED WORKS

We also work on the most delicate iron using quartz sand which provides excellent results. The choice will be made according to the customer’s desired result, but also keeping in mind what is the natural inclination of the material. The manual skill of the operation and the experience of our employees, once again, will participate in the guarantee of the final result.

DRY SANDBLASTING

The sandblasting of the iron involves the use of a current consisting of an air jet and an abrasive material. Since this treatment is not exempt from the formation of dust, it is essential to be able to rely on an effective dust reducing system. Therefore, we use a booth, which allows the non-worn grit to be recovered and recycled, in full respect of the environment.

Among the metals, iron is one of the most delicate materials and for this reason the sandblasting treatment can require special precautions, such as the use of quartz sand.

Depending on the material conformation and unless otherwise agreed with the customer, an industrial sandblasting with metallic grit (a combination of spherical and angular steel) or with Garnet sand is carried out. In the case of delicate surfaces such as stainless steel or galvanized, quartz sand is used, allowing in the latter case a uniform color that is more pleasing to the eye.

Sandblasting Degrees:

• Sa1 (coarse or brushing): the surface appears not perfectly clean, with flakes well adherent on the surface of rust, lamination and painting
• Sa2 or commercial sandblasting: the surface appears free from foreign residues and dark non-uniform color
• Sa2,5 (to white metal): the surface appears perfectly clean and uniform in color
• Sa3 (to deeper white metal): the surface appears perfectly clean and uniform in color that in some metals such as iron turns out shiny.
