Amashanyarazi ya galvanised ni ukurinda kwangirika hejuru yurupapuro rwicyuma no kongera igihe cyakazi.Ubuso bwicyuma gipfundikijwe nicyuma cya zinc.Ubu bwoko bwicyuma cyitwa galvanised coil cyitwa galvanised coil.
Ukurikije uburyo bwo gukora no gutunganya,icyumairashobora kugabanywa muri "Hot-dip galvanised coil coil", "Electro-galvanised coil coil", "Impande zombi kandi zifite impande ebyiri zitandukanye", "ibara ry'icyuma"
Amashanyarazi ashyushye ashyushye.Isahani yoroheje yibizwa muri zinc yashonzepisine, ku buryo urwego ruto rwa zinc rwometse ku buso.Kugeza ubu, ikorwa ahanini nuburyo bukomeza bwo gusya, ni ukuvuga kwibiza kwibiza amabati azengurutswe muri pisine.hamwe na zinc zashongeshejwe kugirango zikore amashanyarazi.
