Abrasive Grains for Stone & Monument Blasting

Even though the intricate and highly skilled craft of hand carving and engraving memorials and cemetery markers was revolutionized with the advent of technology, we continue to cherish the notion of preserving the lives and legacies of those who have come before us. Like the granite itself – which is harder to cut, polish and carve than other rock – density and durability also play important roles in the abrasive grains blast finishing process, transforming simple unadorned slabs into works of art.

Most Durable and Longest Lasting

Saint-Gobain Abrasive Materials' abrasive grains for blast finishing demonstrate consistent industry-leading performance in terms of productivity and life, reduced dusting, more reliable and repeatable finishes, purity for cleaner surfaces, and higher density for greater impact. Our unique process, which involves the fusion of zircon sand and alumina at temperatures of 1950° C, creates particles with high hardness and extreme toughness. With manufacturing sites in Canada, France, China, and the United States, Saint-Gobain ensures a stable, secure supply of blast finishing grits and grains.

Better Performance Means Longer Life

Composed of Saint-Gobain’s 25% alumina-zirconia grains, Stoneblast® is the fusion of zircon sand and alumina at temperatures of 1950° C, which creates particles with high hardness and extreme toughness. The most common applications include high-pressure grinding wheels and pressure blasting of extremely hard surfaces. Stoneblast is fused under carefully controlled conditions for an abrasive that is chemically inert.

Saint-Gobain Abrasive Materials cultivates strong, long-lasting relationships with its customers through close collaboration, working side-by-side to develop innovative solutions for their unique challenges.
