Hot-Rolled Steel vs. Cold-Rolled Steel
Hot-rolled steel is weaker than cold-rolled, but it's also cheaper since it doesn't go through the second production process. However, this doesn't automatically mean cold is better just because it's stronger and more expensive. The more significant difference in how to use it is how specific your material needs are.
