Product Details

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.
