DC01 steel (khoom siv 1.0330) yog European txheem txias-kuav los tiag zoo qis-carbon steel tiaj tiaj khoom rau cov ntawv txias.
Cov npe ntawm cov npe ntawm DC01 Steel
DC01-A: Tso cov teeb meem tsis cuam tshuam rau qhov tshwm sim lossis txheej txheej sab nraud, xws li qhov hws hle, cov duav me me, cov cim me, kos me ntsis thiab xim me ntsis.
DC01-B: Cov chaw zoo dua yuav tsum tsis pub dawb los ntawm qhov tsis xws luag uas tuaj yeem cuam tshuam cov tsos yam tsis zoo ntawm cov xim pleev xim lossis cov pleev xim hluav taws xob zoo. Lwm qhov chaw sab nraud yuav tsum sib ntsib yam tsawg kawg ntawm nto.
DC01+ZE: Electrolytically zinc coated
DC01EK: Conventionally enamelled
