Chrome Bar And Chrome Plated Rod Suppiler
Chrome Plated Bar description
Chrome plated bar/Chrome Plated Rod usually manufactured from cold rolled or hot rolled carbon steel round bars, The surface of the electroplated coating of the chrome-plated rod after treatment has no blackening, peeling, no wrinkling, no pinholes, and the surface of the coating is smooth. Chrome plated bars are the most important parts of manufacturing hydraulic cylinders.
Chrome plated rods are also known as hard chrome plated shafts, chrome steel bar, chrome plated shafting, and chrome rod for hydraulic cylinders.
