RK GARNET #08/12
RK GARNET #08/12: Product Overview
RK GARNET #08/12 is an extra coarse, high-performance abrasive designed for demanding industrial surface preparation applications. Its large particle size and superior hardness enable rapid removal of heavy mill scale, thick rust layers, and stubborn coatings from large steel structures. This grade is especially suitable for projects that require aggressive cleaning and maximum blasting efficiency.
Manufactured from 100% virgin Indian garnet, RK GARNET #08/12 delivers consistent grain size, low dust generation, and excellent cutting power. It is widely used in shipyards, heavy fabrication facilities, offshore structures, and infrastructure maintenance projects where durability and productivity are critical. By providing faster surface preparation and improved blasting performance, RK GARNET #08/12 helps businesses reduce operational time and achieve reliable surface quality for industrial coating systems.
Typical Applications
- Heavy steel structure surface preparation
- Removal of thick mill scale and corrosion layers
- Initial blasting for shipyard hull maintenance
- Offshore platform and marine structure cleaning
- Bridge and large fabrication projects
- Pre-treatment blasting before industrial coatings
