it's high dimensional accuracy,good surface quality,low surface roughness and higher mechanical properties at Cold-rolled state of the metal materials,generally only thin-sheet.Hot-rolled state of the metal relatively low intensity,surface quality is poor but good plasticity,generally is thick-sheet. Generally are hot-rolled first then cold-rolled.
ito ay mataas dimensional katumpakan,mabuting ibabaw kalidad,mababang ibabaw pagkamagaspang at mas mataas na mekanikal na mga katangian sa Cold-pinagsama estado sa mga materyales ng metal 锛 pangkalahatan lamang manipis-sheet.Hot-pinagsama estado ng ang intensity metal na may kababaang,ibabaw kalidad ay mababa ngunit magandang plasticity 锛 pangkalahatan ay makapal-sheet.
