Cold Drawn Steel Bars
With over 40 years of experience, we have developed and specialized in the manufacturing of high-quality cold drawn steel bars in a comprehensive range of sizes, grades, and shapes in accordance to various international standards and customers’ requirements.
What is cold drawn steel bar?
In general, cold drawn steel bar is a steel product which has been plastically deformed by a drawing process at room temperature (hence the name “cold drawn”)to achieve high accuracy shape with bright and smooth finish.
Our Process
Our cold drawn steel bar is produced with either hot rolled steel bar or rod as feedstock material through a multi-step process that begins with shot-blasting to remove scale and rust that is inherent in hot rolled products, and would deteriorate the surfacefinish of the bar if allowed to remain. Next, the feedstock is cold drawn through a tungsten carbide die, where its cross section is reduced and formed into the desired shape. At the final stage, the bar is straightened and polished before covered with rust protective oil and then packed for storage and delivery.

Benefits
Some key benefits of our cold drawn bars include:
– Improved size and section tolerances – reduce machining losses
– Improved surface finish – reduces surface machining and improves quality
– Improved straightness – facilitates automatic bar feeding
– Increases mechanical properties – reduces the need for hardening
