The main difference between Hot - Rolled and Cold Rolled steel is how they are processed. Hot - Rolled steel is rolled at a very high temperature, typically over 1700 ° F, while cold-rolled steel is essentially hot-rolled steel further processed in cold reduction mills. Even beyond their processing temperature differences, there are numerous key differences between Hot - Rolled Steel and Cold- Rolled Steel.

Electrogalvanized Steel VS Hot Dipped Galvanized Steel
26 July 2021
What is Galvanized Steel? Galvanized steel is coated with zinc to help prevent corrosion. Zinc forms a barrier, defending the metal itself from rust and other forms of corrosion. In addition, zinc reacts with oxygen when exposed to the atmosphere, thus forming zinc oxide. Furthermore, the zinc oxide reacts with carbon dioxide to firm a zinc carbonate. This stops further corrosion in most circumstances,…
