Steel round bars can be categorized into two main groups, namely hot-rolled round bars and cold-drawn round bars, depending on their shape.
Hot-rolled round bars are produced by heating a steel billet until it becomes malleable and then passing it through a series of rollers to achieve the desired shape. This manufacturing process results in a rougher surface texture and a slightly larger diameter when compared to cold-drawn round bars. Hot-rolled round bars find common usage in construction, engineering, and manufacturing applications where strength and durability play a crucial role.
On the other hand, cold-drawn round bars are manufactured by pulling a hot-rolled round bar through a series of dies at room temperature. This process enhances the dimensional accuracy, surface finish, and mechanical properties of the steel. Cold-drawn round bars possess a smoother surface texture and a more precise diameter, making them suitable for applications that demand tight tolerances, such as precision machining, automotive components, and machinery shafts.
In conclusion, the classification of steel round bars, based on their shape, is determined by the specific manufacturing process employed. Hot-rolled round bars exhibit rougher surfaces and slightly larger diameters, while cold-drawn round bars boast smoother surfaces and more precise dimensions. The choice between these two categories depends on the specific requirements of the given application.

Hot-rolled round bars are rougher and slightly larger in diameter, while cold-drawn round bars have a smoother surface texture and more precise dimensions. The choice between these two categories depends on the specific requirements of the application.
Steel round bars are classified based on their shape as either hot-rolled or cold-drawn round bars.
