Ikhoyili Yensimbi ye-Galvalume (i-Bobin De Aco Galvalum) inazo zombili izici zensimbi eyakhiwe ngokushisa-diphu kanye nensimbi ye-aluminiyamu yediphu eshisayo.Ngakho-ke, lapho kusetshenziswa ishidi lensimbi elidiphu elishisayo, kungasetshenziswa ikhoyili yensimbi ye-galvalume, futhi ingabuyisela ingxenye yeshidi lensimbi ye-aluminiyamu yokucwilisa eshisayo.Inohlu olubanzi lwezinhlelo zokusebenza.
Mayelana nokuhlinzekwa kanye nesidingo, ngemva kweminyaka yokulungiswa nokuncintisana kwemakethe, imboni yaseChina yamakhoyili ensimbi ye-galvalume isizinzile kancane kancane.Ubudlelwano bokuhlinzekwa kwemakethe kanye nesidingo buyalingana.Izinga lokukhiqiza nokuthengisa lingaphezu kwama-90% njalo ngonyaka, futhi inani elikhulu lemikhiqizo lithunyelwa kwamanye amazwe minyaka yonke.
