Before heading to any shop and buying steel for your latest DIY project, it’s necessary to educate yourself about the different types of steel in the market. This is because being well informed can lead you to the tools you need.
Steel coil suppliers in the U.S. produces two types of steel, hot rolled and cold rolled. Aside from their names, there are other significant differences you should be aware of.
Hot rolled steel
Yes, you guessed it right. Hot rolled steel undergoes an intensive heating process to achieve a scaled surface finish, with its edges slightly rounded and curved. To achieve this yourself, you need to heat rectangular billets and place them at a high temperature. Put the billets under high-pressure compression mechanisms as well to achieve its finished dimensions. Steel coils are rolled and cooled, while steel bars and plates are blocked and packaged.
As hot rolled steel undergoes a shorter process, it’s less costly than its alternative. Moreover, it’s ideal for larger materials like construction, transport, and shipbuilding because it retains its durability and malleability.
Cold rolled steel
Cold rolled steel, on the other hand, is like hot rolled steel but has other additional processes. Steel is cooled down and rolled once again for better measurement and a smoother finish. The term cold rolled can be a bit tricky, though. Technically speaking, cold rolled steel are sheets that undergo compression between rollers.
Cold rolled steel have smoother finishes and have more well-defined edges and curves. Therefore, cold rolled steel is a great choice for projects that require precision and aesthetic touches.
What would your next DIY project be? Now that you know the two basic types of steel, you can choose which is more suitable to work with.
