Kev txheeb xyuas qhov zoo ntawm galvanized zinc coated steel kauj yuav tsum muaj kev ntsuam xyuas los ntawm ntau qhov ntev, nrog rau cov tsos, muaj pes tsawg leeg, thickness, adhesion, thiab corrosion kuj. Cov hauv qab no yog cov txheej txheem tshwj xeeb thiab cov cim tseem ceeb:
Kev Ntsuam Xyuas Kev Pom Zoo: Kev ntsuam xyuas thawj zaug ntawm txheej txheej thiab qhov tsis xws luag
Kev soj ntsuam pom: Saib xyuas qhov chaw nyob rau hauv lub teeb ntuj kom ntseeg tau tias nws yog du thiab tiaj tus, nrog lub silvery -white metallic luster thiab qhov txawv "hnub qub-zoo li" kev ntxhib los mos.
Cov khoom tsim nyog yuav tsum tsis muaj qhov sib txawv ntawm cov xim sib txawv, tsis muaj xim, xim dub, tev, flaking, lossis qhov chaw tsis muaj xim.
Me ntsis zinc flow marks yog tso cai, tab sis yuav tsum tsis txhob cuam tshuam tag nrho kev ua tau zoo.
Magnifying Glass Pab: Siv 5-10x magnifying iav los tshuaj xyuas cov ntsiab lus hauv zos, lees paub qhov tsis muaj pinholes, npuas, lossis kev suav nrog.
