This document specifies the classification and code, dimension, dimension tolerance, shape, measurement of dimension and shape, weight and rounding off for numerical values for twin-roll casting thin gauge hot-rolled steel strip and sheet (hereinafter referred to as ¡°steel strip and sheet¡±). This document applies to hot-rolled thin steel strips, slitting steel strips, as well as steel strip cross-cut steel plates ¨C with a thickness of 0.6 mm ~ 2.0 mm and a width of 900 mm ~ 1800 mm ¨C which are produced by twin-roll casting and rolling process.
