1. Cov txheej txheem ntau lawm
Cov txheej txheem ntau lawm ntawm galvalume nplooj ntawv thiab cov ntawv txias-dov hlau yog txawv. Cold-rolled steel daim hlau yog mechanically ua thiab undergo cov txheej txheem xws li dov, cua sov, txias, thiab trimming thaum kawg tau txais cov khoom. Galvalume phaj yog txheej ntawm aluminium-zinc alloy plated rau saum npoo ntawm steel phaj thiab ua tiav los ntawm cov txheej txheem tshwj xeeb. Cov txheej txheem no tuaj yeem ua haujlwm tau zoo rau lub neej ntawm cov hlau phaj thiab txhim kho cov khoom siv kho tshuab thiab corrosion kuj.
2. Cov khoom siv sib txawv
Cov cuab yeej cuab tam ntawm galvalume thiab cov ntawv txias-dov steel kuj txawv. Cold-dov steel phaj muaj lub zog siab thiab hardness, tab sis tsis zoo toughness thiab yooj yim tawg. Cov ntawv galvanized muaj qhov zoo toughness thiab plasticity, tuaj yeem hloov kho kom haum rau kev tsim qauv tsim qauv, thiab tsis yooj yim rau deform thiab tawg.
3. Cov khoom sib txawv corrosion kuj
Txij li qhov saum npoo ntawm galvalume phaj yog coated nrog ib txheej ntawm aluminium-zinc alloy, nws muaj corrosion kuj zoo, tuaj yeem siv tau ntev hauv huab cua hnyav, thiab tsis yooj yim corroded. Cold-rolled steel daim hlau tsuas yog muaj peev xwm los tiv thaiv corrosion tom qab nto tau pleev xim thiab lwm yam kev kho mob, tab sis lawv lub neej kev pab cuam luv luv.
