Ukwakheka kwekhoyili yensimbi ye-Zincalume ingu-55% we-aluminium, 43.4% kanye no-1.6% we-silicon ephulukiswe ngo-600℃.Ikhoyili yensimbi yeZinalume(bobina de galvalume) inobuso obumhlophe obusiliva.
Amakhoyili e-Galvalume asetshenziswa kakhulu ekwakhiweni, embonini ekhanyayo, ezimotweni, ezintweni zikagesi zasendlini, e-elekthronikhi, ezolimo, ezokufuywa kwezilwane nezokudoba, ukupakishwa kwempahla nezinye izimboni.Ukusetshenziswa kwayo ikakhulukazi kuyizingxenye ezimbili: amashidi ensimbi e-galvalume kanye namakhoyili apendwe ngaphambili.Eminyakeni yamuva nje, izimoto, ukwakhiwa, izinto zikagesi zasendlini kanye nezinye izimboni zaseChina ziye zabona ukukhula okusheshayo kwesidingo semikhiqizo ye-galvalume, ikakhulukazi ngokuthuthuka okusheshayo kwezakhiwo zokukhanya, ukwanda kwaminyaka yonke kokuphuma kwezimoto, ukuthandwa okubanzi kwemishini yasendlini, ngokuhlanganyela. amabhizinisi, izinto zikagesi eziphethwe ngokuphelele, kanye nenani elikhulu lemikhiqizo kagesi zithunyelwa ngaphandle, ukuze ukusetshenziswa kwamakhoyili e-galvalume/aluzinc kunyuke ngokushesha.Ukukhiqizwa kwasekhaya kwemikhiqizo ye-galvalume kuye kwathuthuka ngokushesha eminyakeni yamuva.
