Bright Bars are cold drawn/ground/peeled plain bars produced from hot rolled plain bars/wire rods. Bright Bars have a smooth and a bright surface with Accurate Tolerance on the dimensions, they possess improved mechanical properties, greater dimensional accuracy, better surface integrity and higher machinability, and these superior product qualities provide a number of significant design advantages & benefits
BRIGHT BARS - THE MANUFACTURING PROCESS
The raw material used in the bright bar manufacturing process are called ‘black bars’ – steel wire rods that are mostly in coil form. They are cleaned by removing their scales, which is done either by ‘pickling’ (acid cleansing) or ‘shot blasting’ (blasting steel balls) techniques. Once cleaned, the curvy coil is opened, straightened and fed into the Combined Wire Drawing machine. In the drawing machine, the wire rods are reduced (‘drawn’) to a smaller diameter, straightened and polished/cut to required specifics. The resultant finished product is a Bright Bar (called ‘bright’ due to its shiny finish), also called a Cold Drawn Bar.
APPLICATIONS OF BRIGHT BARS
Bright bars are in high demand for making different types of fastener products like bolts, nuts, pins, and rivets which could be micro size to mega size also depending upon the application and customs requirements. The bright bars in round shape are perfect base material for machining and making these fasteners that are used in industrial ambiences or the domestic applications.
Automobile frames and chassis are now being made with different grades of steel bright bars in flats, squares, and rounds.
Bright bars manufacturers in India and around the world are supplying high grade material for the making of tools and implements of direct use by technicians and mechanics. The round bright bars are a good choice for machining them economically and derive tools in custom shapes and forms.
Bright bars in different shapes and sizes are directly used for manufacturing the machine components like the smaller ones used in the automobile engines. The manufacturers are supplying very high quality SS base products to the ancillaries and brands for making these machine components.
