Abrasives Grains can be distinguished in a variety of ways- their hardness, color, chemical composition, crystal shape, and friability, to name but a few. Since the chemical composition- that is, the type of material- determines many of the other characteristics, we use that as the primary means of distinguishing one type of abrasive from another. Our variety are Brown Fused Alumina,ink Fused Alumina, Steel Grits & Shots. These grade aggregates are for use in industrial flooring to produce heavy-duty concrete floor. These treated slabs resist impact and withstand exposure to water, oil and chemical. The closely interlocking particles of the aggregate give excellent bounding. This is also use for making tiles and for road surface dressing.
