1. Kub dov, khaus, pov tseg thiab qis. Cov hlau pleev qhov dej saum npoo yog npub ntub thiab yog me ntsis ntxhib.
2. Polished deg ua: lub nto yog uniformly hauv av, thiab qhov loj me me lis yog 80 ~ 100; Qhov saum npoo yog ci ntsa iab thiab cov nplaim muaj nplua zoo. Feem ntau nws yog siv txoj hlua khi ntawm 180 ~ 200 ntawm 2A lossis 2B phaj.
3. Unidirectional nto ua, tsis yoojyim, qhov kev ua haujlwm saum npoo no yuav yog qhov ntau yam hauv architectural applications. Cov txheej txheem cov kauj ruam yog ua ntej polished nrog ib tug ntxhib abrasive thiab thaum kawg nrog ib tug abrasive muaj ib qhov loj me me ntawm 180.
4. Tom qab txias rolling, annealing, descaling, thiab thaum kawg lub teeb dov nrog matte yob. Qhov no yog qhov feem ntau siv los ua cov ntawv siv architectural. Tsuas yog lub xeem me txias dov nrog ib tug polishing yob tom qab ntuav thiab zom zaws, lwm cov txheej txheem yog tib yam li 2D, nrog ib qhov chaw me me ci ci uas yuav tsum tau ci ntsa iab thiab ci ntsa iab.
