Nelson Metal Industries — Round Bar Types
Types

Hot Rolled vs. Cold Drawn Round Bar

Hot Rolled Round Bar

Hot Rolled Round Bar

Produced by rolling heated steel billets through a series of rollers, hot rolled bars have a black-oxide surface finish and looser dimensional tolerance. They're the cost-effective choice for general structural and fabrication use where tight tolerance isn't critical.

Cold Drawn Round Bar

Cold Drawn Round Bar

Pulled through a die at room temperature, cold drawn (bright/peeled) bars offer tighter dimensional tolerance, a smoother surface finish, and improved mechanical properties — ideal for precision machining, shafting, and components requiring a superior finish.
