Isakhiwo sokugquma somgca wensimbi ye-galvalume yi-Zn-Al alloy, kwaye ukubunjwa kwe-coating ngu-55% Al, 43.3% Zn, kunye ne-1.6% yeSi.Ngenxa yokumelana nokugqwesa kwayo okugqwesileyo, olu hlobo lwentsimbi lusetyenziswa kakhulu kwihlabathi liphela.
Ukuphuhliswa kwentsimbi ye-aluzinc.Ngokubhekiselele kunikezelo kunye nemfuno, emva kweminyaka yohlengahlengiso kunye nokhuphiswano lwemarike, ishishini le-coil yensimbi ye-galvalume yaseChina liye lazinza ngokuthe ngcembe.Ubudlelwane bobonelelo lwemarike kunye nemfuno bulungelelanisiwe.Izinga lemveliso kunye nentengiso lingaphezulu kwe-90% ngonyaka, kwaye inani elikhulu leemveliso zithunyelwa ngaphandle minyaka le.
