After passing through the rollers in a rolling mill, however, the sheet metal will develop a uniform size and shape. It's important to note that rolling mills support both cold rolling and hot rolling processes. Cold rolling means the sheet metal is pressed between the rollers at or near room temperature. Hot rolling, on the other, means the ...
