Tsis tas li ntawd, txias dov kuj suav nrog qee yam tsis tshua muaj ntau yam, xws li txias dov lub thawv phaj, txias dov tawv phaj, txias dov ntawv, thiab lwm yam. Ob pawg no feem ntau muaj npe vim lawv cov duab sib txawv thiab cov khoom siv. Lub tsev galvanizing nrog pre-annealing kho cov txheej txheem galvanizing;
