Cold formed vs hot rolled
WebThe difference between the two lies in the material that the steel tube or profile was manufactured or rolled from. Hot Rolled material is material that is formed when the steel is above its recrystallization temperature while Cold Rolled material is formed when the temperature of the steel is below its recrystallization temperature. WebFirst off, it’s important to note that the primary difference between hot and cold rolled steel is the process of how it gets manufactured. Hot rolling is when you process the steel with …
