CK22 CK25 CK30 CK45 CK50 Hot Rolled Steel Coil 1000mm 1250mm 1500mm Width HRC Industrial Grade
Zhengde hot-rolled steel coils are manufactured using slabs (primarily continuous casting slabs) as raw materials. After heating, they are processed through rough rolling and finishing rolling units to produce high-quality strip steel. The hot steel strip exiting the final rolling mill is cooled to specified temperatures via laminar flow and coiled into steel strip coils, ready for various finishing operations based on customer requirements.
