Steel shot & steel grit are two different shapes of steel abrasives each of which are suitable for different types of industrial applications. Steel shot is spherical widely used abrasive for stripping & cleaning metal surfaces producing
smooth polished finishes.
Steel grit is an angular shaped abrasive used for aggressive cleaning and stripping of steel and foundry metals. Its angular shape produces an etching on hard metals which provides better adhesion for coatings including paints, epoxy, enamel and rubber.
Rock Garnet Trading represents one of the biggest factories in Korea producing various steel shot balls and steel grit. All products are manufactured by a fully automatic system under strict inspection and supervision.
Process
Steel shot & steel grit have similar manufacturing processes.
