Hot rolled steel profiles are produced by heating a billet or slab and then rolling it into the desired shape while it is still hot. This process allows for a greater variety of shapes and sizes, as well as improved mechanical properties.
On the other hand, cold formed steel profiles are created by bending or shaping steel sheets or strips at room temperature. This method of production results in profiles that are typically thinner and have tighter tolerances. Cold forming also allows for more intricate shapes and designs, making it suitable for applications where precision and aesthetics are important.
In summary, the main difference between hot rolled and cold formed steel profiles lies in the manufacturing process and the resulting properties. Hot rolled profiles offer greater versatility and strength, while cold formed profiles are more precise and suitable for intricate designs.
Hot rolled steel profiles are produced through a heating process where the steel is formed into the desired shape while it is at a high temperature. This results in a more malleable and flexible material with a rough outer surface. On the other hand, cold formed steel profiles are created by shaping the steel at room temperature, usually through a bending or rolling process. This produces a stronger and more precise profile with a smoother finish. Overall, the main difference lies in the manufacturing process and the properties of the final product.
Hot rolled steel profiles are made by heating a steel billet or ingot and then passing it through a series of rollers to achieve the desired shape and size. This process results in a finished product with a rough surface texture and less precise dimensions. On the other hand, cold formed steel profiles are made by bending or forming steel sheets or strips at room temperature. This process allows for greater control over the shape and dimensions of the final product, resulting in smoother surfaces and tighter tolerances. Additionally, cold formed steel profiles tend to have greater strength and stiffness compared to hot rolled profiles due to the work hardening that occurs during the forming process.
