kub-dip galvanized steel
DX51D + Z kub-dip galvanized steel yog raws li tus qauv EN, thawj 'D' txhais tau tias qhov no yog hom hlau rau kev siv txias txias, cov khoom siv ntawm DX51D + Z yog 1.0226, qhov kawg 'D' qhia cov txheej txheem thev naus laus zis kub -dip galvanizing, raws li cov neeg siv khoom sib txawv ntawm zinc zinc- hlau alloy coated (ZF), zinc-aluminium alloy coated (ZA), aluminium-zinc alloy coated (AZ).
DX51D + Z galvanized ntawv kuj tseem muaj cov ntawv galvanized. DX51D + Z yog ib daim ntawv galvanized nyob rau hauv ntau yam ntaub ntawv, uas yuav ua tau nrog xoom spangle los yog li niaj zaus paj spangle nto. Tab sis tsuas yog siv tau yooj yim khoov thiab deformation.
DX51D + Z galvanized steel ntawv hais txog qhov chaw ntawm ib txheej ntawm zinc phaj. Galvanizing yog ib qho kev siv ntau thiab siv tau zoo ntawm kev khaws cia corrosion.
