JIS G3141 is a standard in the Japanese Industrial Standards (JIS), which is specifically for the technical specifications and quality requirements of cold-rolled steel sheets and coils. This standard covers all aspects of cold-rolled steel sheets and coils, including chemical composition, mechanical properties, dimensional representation methods, tolerances, weight, appearance, test methods, etc.
JIS G3141 applies to cold-rolled steel sheets and strips, including mirror steel strips (cold-rolled steel strips with a width of less than 600mm) and steel sheets cut from mirror steel strips.
