Steel Rounds are the basic raw material used in a variety of engineering, auto and other ancillary industries. Syber boasts of the best reduction ratios in the industry and hence our products give the best forgeability and machinability values to the customers. We have the widest range in terms of Mild Steel, Carbon steel, Alloy Steel, Free Cutting Steel and all Special Grades.
Round Bar diameter ranging from 12mm to 140mm
Steel Bright Bars or Cold Drawn Bars are manufactured by passing hot rolled steel bars through dies in a cold process. It improves size selection in close tolerances and straightness, which facilitates automatic bar feeding in CNC.
Bright Bar diameter ranging from 16mm to 50mm
We manufacture our wire rods through the latest direct hot charging technique, via our concast facility. The product is rolled in our fully automatic steel rolling mill under the banner of Prime Steel processors. We produce low carbon, medium carbon, high carbon, cold heading quality(CHQ).
Bright Bar diameter ranging from 6mm to 28mm
Round Cornered Square bars or RCS are mainly used for drop forged components in the automotive industry. Our RCS Products have a uniform internal structure and a very good surface quality. We manufacture a wide range of RCS bars in various grades and sizes, according to the customer’s requirements.
Square Bar/Round Cornered Square diameter ranging from 30mm to 125mm
Steel Hexagons are long steel bars having 6 sides. They are used in a number of engineering products such as nuts, bolts, hydraulic fittings etc. We have a fully dedicated rolling mill to manufacture Hex Bars in almost all grades and sizes. We have been pioneers in hex bars since 1978.
Hex Bar diameter ranging from 17mm to 78mm
