Difference between cold formed steel and hot rolled steel

Updated: Jul 3, 2023

Cold-formed steel and hot-rolled steel are two different manufacturing processes used to produce steel components with distinct characteristics and applications. Here are thePEB key differences between cold-formed steel and hot-rolled steel.

Cold Formed Steel

Hot Rolled Steel

Manufacturing Process

Cold-formed steel is produced by rolling or pressing steel sheets or strips at room temperature. The steel is shaped into the desired profiles using rollers or presses, without applying heat

Hot-rolled steel is manufactured by heating the steel above its recrystallization temperature and then passing it through rollers to shape it into the desired profiles. This process involves high temperatures and requires careful cooling to achieve the desired properties.

Material Properties

Cold-formed steel exhibits higher yield strength but lower tensile strength compared to hot-rolled steel. It is generally thinner and lighter, making it suitable for applications that prioritize strength-to-weight ratio, such as framing systems, roofing, and wall panels.

Hot-rolled steel has lower yield strength but higher tensile strength compared to cold-formed steel. It is thicker and denser, making it ideal for applications that require load-bearing capacity, such as structural beams, columns, and heavy-duty construction.

Surface Finish

Cold-formed steel typically has a smooth and uniform surface finish due to the manufacturing process. This makes it suitable for applications where a sleek appearance is desired or where surface imperfections may impact performance.

Hot-rolled steel often has a rough and scaled surface finish due to the high temperatures involved. This surface texture may be desirable in certain applications, such as where additional adhesion is required, or it can be further processed to achieve a smoother finish.

Understanding the differences between cold-formed steel and hot-rolled steel is crucial for selecting the appropriate material for specific applications. Factors such as structural requirements, and design considerations play significant roles in determining the most suitable steel option for a given project.
