Steel Media

For all kinds of surface processing, we provide a wide variety of steel burnishing media in different materials and peculiar shapes ranging from diagonal to oval to spherical, to be used in rotating horizontal barrels, vibratory tubs, trough or bowl-type finishing machines, and turret-mounted drum machines for polishing or deburring rough surface of molded, cast or forged articles.

Normally, carbon steel media are used for common surface polishing with mild chemical compounds. While stainless media are used where there is a corrosive chemical involved, some people prefer chrome alloy steel than carbon steel media for the much better durability.
