Q345 Cold Rolled Sheet
With better surface characteristics and fewer imperfections, Cold Rolled Steel sheet is most commonly used for precise applications where appearances are important. In addition, because of its tight size tolerance and excellent machinability, Cold Rolled Steel sheet is used across a wide variety of industries.
Thickness:2-400mm
Technology:Hot rolled ; cold rolled；colled drawn
Width:600-2000mm
Length:1-12m or as request
Cold rolled steel can be cut, bent, punched, drilled and formed more easily than other metals, while still offering workable mechanical properties and low yield strength. Best of all, the glossy and clean finish makes it the first choice for most machinery production companies. That's why you can find cold-rolled steel in most household appliances, including washers, dryers, refrigerators, fans, and microwave ovens.
