Cold Rolled sheet
Railroad tracks and construction projects often use hot rolled steel. Hot rolled steel can
often be identified by the following characteristics: A scaled surface—a remnant of cooling
from extreme temperatures. Slightly rounded edges and corners for bar and plate products
(due to shrinkage and less precise finishing.Cold-rolled steel refers to low-carbon steel
produced by a “cold rolling” method and processed at near normal room temperatures.
Cold-rolled steel sheets are commonly used for engineered products where tight tolerances,
concentricity, straightness and coated surfaces are required.
