Thaum lub 'meter' steel workpieces, xaiv cov hlau, feem ntau yog qhov kev txiav txim siab tseem ceeb yog: cov khoom siv kho tshuab (lub zog, toughness, thiab lwm yam), kev ua haujlwm thiab cov nqi.Tab sis rau qhov chaw galvanized, muaj pes tsawg leeg ntawm kev xaiv cov ntaub ntawv, qhov zoo ntawm kub-dip galvanizing muaj kev cuam tshuam zoo.

Ib qho ntawm corrosion ntawm galvanized steel corrosion tiv thaiv txoj kev rau ntau qhov chaw tab sis yuav tsum tau them sai sai rau kev siv cov yam ntxwv, yuav luag tag nrho cov hlau yog tsim rau kub-dip galvanizing, xws li kub-dub, txias-dov hlau, cam khwb cia hlau, forged steel, cam khwb cia hlau cov ntaub ntawv xws li steel, feem ntau yog rau anti-corrosion yuav kub-dip galvanizing txoj kev, thiaj li yuav txhim kho lub neej.

Qhov ntau tau siv cov pa roj carbon zoo tib yam thiab cov hlau tsis tshua muaj siab-lub zog steel galvanized cov khoom siv feem ntau.Txawm li cas los xij, cov khoom xyaw tseem ceeb kom tau txais cov txheej txheem galvanized zoo heev ntawm cov khoom siv hlau yog: carbon cov ntsiab lus ≤0.25%, phosphorus cov ntsiab lus ≤0.04%, manganese cov ntsiab lus ≤1.35%, silicon ntsiab lus ≤0.03% lossis 0.15% ~ 0.25% (0.03% rau 0.15% ntawm qhov hnyav hlau poob, lub workpiece tsaus nti, tev).Obviously, tsis yog txhua yam ntawm cov pa roj carbon zoo tib yam thiab qis-alloy high-strength steel qauv ua tau raws li qhov yuav tsum tau muaj ntawm no muaj pes tsawg leeg.
