Glass Beads 40 mesh

How 40 Mesh Glass Beads Perform in Blasting and Peening

At 40 mesh (approximately 425 microns), these glass beads strike a balance between coverage rate and surface refinement. The spherical particle shape delivers consistent impact energy transfer, making the media effective for shot peening applications where compressive stress must be introduced without excessive surface roughness. In cosmetic finishing, the same controlled impact produces a uniform satin or matte appearance valued in architectural metalwork, automotive restoration, and consumer product manufacturing.

Because glass beads are chemically inert and free from free-iron contaminants, they are safe for use on stainless steel and aluminium where ferrous residue could cause post-blast corrosion or discolouration. The media can be recycled multiple times in closed-loop blast cabinets, provided proper dust collection and classification are maintained.

Selecting the Right Glass Bead Grade for Your Process

Mesh size is the primary selection variable. 40 mesh is a medium-fine grade that suits general-purpose peening and finishing. For heavier peening or faster stock removal, coarser grades (20–30 mesh) may be more appropriate. For ultra-fine cosmetic finishing or delicate electronic components, finer grades (60–80 mesh or higher) are typically specified. SPA2Z can advise on grade selection based on your substrate material, desired surface profile, and blast equipment configuration.

Key process variables that influence finish quality include blast pressure, nozzle distance, angle of impingement, and media cleanliness. Our team can provide technical guidance to help you dial in these parameters for repeatable results.

Packaging and Supply Options

We offer flexible packaging to match your consumption volume and handling setup:

• 25 kg bag – convenient for small-batch blasting and manual handling
• 50 kg bag – standard industrial pack for medium-volume users
• 1-ton jumbo bag – bulk option for high-consumption blasting operations
• Bulk tote / drum pack – alternative bulk formats for specific handling requirements

Minimum order quantities and lead times vary by grade and destination. Contact SPA2Z with your required mesh size, monthly consumption, and delivery location for a tailored quotation.
