Zaj sawv Chromate Passivation (C2C) yog ua raws li electrogalvanizing los tsim cov xim uas passivation zaj duab xis nrog lub tuab ntawm li 8-15μm. Lub ntsev ua tshuaj txau tshuaj yuav nyob ntev tshaj 72 teev yam tsis muaj xeb dawb.

Ua los ntawm Q235 carbon hlau thiab lwm cov ntaub ntawv, qhov chaw yog Electro-greating, thiab cov txheej txheem txheej xim dawb yog 5-12μm, uas ua tau raws li cov kev kho mob tom qab muaj 5,

Kev kho mob bolts muaj xov ntawm ob xaus thiab tus pas nrig liab nyob hauv nruab nrab, uas yog siv los txuas cov phiaj tuab lossis teeb tsa GB / T 901). Cov ntaub ntawv cov khoom siv yog 45 # steel lossis 40cr, nrog galvanized lossis dub dub nto.

Lub hexagon ntswj pas nrig lub taub hau muaj lub taub hau hexagon npog qhov thiab yuav tsum tau ua kom nruj nrog cov hexagon ntsaws (txheem GB / T 70.1). Cov ntaub ntawv cov khoom siv tau 35crmo lossis 42crmo, thiab cov kev kho deg tau muab faib ua peb hom: electrogalvanized, xim zinc-plated, thiab dub zinc-plated.
