Before you buy anything at a steel service center, you should understand the different options so that you receive the best option for your needs. The first significant decision when shopping for rolled steel is whether you want hot or cold rolled. Each manufacturing method has a significantly different impact on the metal’s performance. Below is more information about how these processes differ.

Hot Rolled Steel

The Manufacturing Process

This process involves rolling the steel at a temperature above its recrystallization temperature, which is usually 1700 F or more. Heating it to this temperature makes it easier to form and shape. As a result, manufacturers can make exceptionally large sizes to suit massive projects. Once the steel recrystallizes after rolling, the surface forms a scaly finish and may not have a uniform shape.

When It’s Best

When visiting a steel service center for structural components, choose a hot rolled option. It is popular for sheet metal, I beams, vehicle frames, and agricultural equipment. This is ideal because the pieces are large, but you do not need a precise shape or finish.

Cold Rolled Steel

The Manufacturing Process

To make cold rolled steel, manufacturers first perform hot rolling, before processing the metal further after it cools to room temperature. They will roll the steel again with extreme pressure at room temperature. This limits the metal to being flat, square, or round. However, there are many finishing options to alter the look and structure of the material.

For example, cold drawing increases the tensile strength for building products, which improves the metal’s ability to withstand tension and avoid breakage. Turning and polishing the metal will remove any imperfections on the surface and make the finish attractive for projects where aesthetics are a priority.

When It’s Best

The finishing process in cold rolling provides significant control over the shape and finish. This makes it a reliable choice when you need the metal to be attractive, such as for home appliances, furniture, bars, rods, or roof systems.
