Glass Bead Blasting

Uniform satin surface finish achieved by projecting glass beads. Aesthetic consistency, hygienic preparation and removal of manufacturing marks.

Professional surface finishing

We specialise in glass bead blasting of stainless steel, a process that deep-cleans parts and removes any impurities.

This treatment delivers uniform finishes, improves corrosion resistance and increases the durability and appearance of materials. It is an essential finish in sectors such as food, pharmaceuticals and construction.

Key benefits

Aesthetic consistency Even satin finish
Hygiene Easy-to-clean surface
Mark removal Welding, polishing, handling
Surface preparation Ideal before passivation

Blasting process

A controlled methodology for uniform, repeatable finishes.

Preparation

Pre-cleaning of the surface to remove grease, oil, dust and contaminants that could affect the finish.

Solvent degreasing
Weld cleaning
Thorough drying
Masking of sensitive areas

Blasting

Glass beads projected with compressed air, with control of pressure, distance and angle of impact.

Controlled pressure 2-6 bar
Optimal distance 15-30 cm
Angle 45-90°
Even passes

Cleaning

Removal of residual beads, dust and particles by compressed-air blow-off and final cleaning.

Filtered air blow-off
Vacuuming of cavities
Thread cleaning
Visual inspection

Verification

Inspection of finish uniformity, surface roughness and absence of defects or untreated areas.

Full visual inspection
Uniformity check
Roughness measurement
Parameter logging

Expected results
