Cold "rolled" steel is often used to describe a range of finishing processes though technically "cold rolled" applies only to sheets that undergo compression between rollers Steel forms that are pulled such as bars or tubes are "drawn " not rolled Other cold finishing processes include turning grinding and polishing—each of which is used to modify existing hot rolled stock into more refined products

Less expensive to transport Due to the larger number of cold-Rolled sheet pile manufacturers there is a higher chance that you can find a mill located nearby than if you were to purchase hot-rolled sheet piles Additionally the larger selection of cold-rolled sheet piles may allow you to find sections with a section modulus closer to your design specifications without a large increase in weight

The use of roll stands which contain pairs of rolls are grouped into rolling mills and are capable of quickly processing the metal into products Hot Rolled Process The milling process performed at more than 1700 degrees Fahrenheit is called hot rolling and is above steel's recrystallization temp This process allows for the metal to be shaped

Cold rolled sheet can be produced in various conditions such as skin-rolled quarter hard half hard full hard depending on how much cold work has been performed This cold working (hardness) is often called temper although this has nothing to do with heat treatment temper In skin rolling the metal is reduced by 0 5 to 1% and results in a surface that is smooth and the yield point
