The thickness of cold-rolled strip and sheet is 0.1, the width is 100, both are hot rolled steel strip or steel plate as raw material, at room temperature by cold rolling mill.
Cold rolled strip and sheet has the advantages of smooth surface, flatness, high precision and good mechanical properties, the products are mostly rolled, and a large part is processed into coated steel plate factory.
The production efficiency of rolled cold-rolled sheet is high, easy to use, conducive to subsequent processing, so widely used, has gradually replaced the same thickness of hot-rolled sheet (see sheet laminated), only a small number of special-purpose cold-rolled alloy steel plate to take the single sheet rolling, cold-rolled strip and sheet production in the industrialized countries accounted for about 30% of the total output of steel.
