Glass bead Abrasive (GB-2/Course I ‘O’)

This product description for the GB-2 / Coarse I ‘O’ is crafted to emphasize power, impact, and industrial durability. It targets engineers and heavy-industry specialists who need the highest kinetic energy possible from a glass bead.

Product Description: Glass Bead Abrasive GB-2 | Coarse I ‘O’ (600-800 μm)

Maximum Impact Energy for Heavy-Duty Industrial Applications

The GB-2 (Coarse I ‘O’) represents the heavyweight tier of spherical glass media. With a substantial particle size of 600-800 microns, these beads are engineered for high-velocity impact. This grade is specifically designed for structural shot peening and aggressive cleaning tasks where standard fine-grade abrasives lack the mass to achieve the required surface profile or compressive stress.

Key Performance Features:

• Structural Shot Peening: The high mass-to-volume ratio of the 600-800 μm beads makes them superior for deep-layer compressive stress, effectively preventing fatigue failure in heavy forgings and structural steel.

• Aggressive Industrial Cleaning: Powerfully removes thick heat-treat scale, heavy oxidation, and rugged industrial coatings that finer beads simply cannot penetrate.

• Dimensional Integrity: Despite its aggressive cleaning power, the spherical shape ensures that surface contaminants are removed through impact rather than abrasion, preserving the base metal’s weight and dimensions.

• Consistent Matte Texturing: Delivers a distinctive, high-profile matte finish, often used for aesthetic industrial design or as a mechanical key for heavy-duty bonding agents.

Technical Specifications:

• Grade: GB-2 / Coarse I ‘O’

• Micron Range: 600 – 800 μm

• U.S. Mesh Equivalent: Approx. 20 – 30 Mesh

• Hardness: 6–7 Mohs

• Composition: Chemically inert soda-lime glass

• Roundness: ≥ 70% true spheres for uniform energy distribution.

Best Used For:

• Heavy Machinery & Forging: Peening and cleaning large-scale industrial components, gears, and shafts.

• Oil & Gas Industry: Stress-relieving drill strings and cleaning heavy-duty valves or pipe fittings.

• Casting Facilities: Rapid removal of investment materials and sand from large non-ferrous castings.

• Anti-Skid Additives: Often mixed into heavy floor coatings and paints to provide a high-durability, textured grip.

Why Choose GB-2?

When your project demands more than just a light polish, the GB-2 Coarse I delivers. It provides the maximum impact force available in the glass bead category, ensuring that even the toughest scales are stripped and the deepest peening requirements are met with industrial efficiency.
