Ibyuma bya galvanizike ni ubwoko bwibikoresho byitwa (zinc, aluminium) bisizwe hejuru yicyuma kirekire kandi kigufi cyicyuma gikonje cyangwa kizunguruka.Gishyushya bishyushye bifite ibyiza byo gutwikira kimwe, gukomera gukomeye hamwe nubuzima burebure.Imyitwarire igoye yumubiri na chimique hagati yubushyuhe bwa dip galvanised strip substrate hamwe nigisubizo cyashongeshejwe cyashongeshejwe cyangirika cyangirika zinc-fer alloy layer igizwe nuburyo bworoshye.Umuti wa aliyumu uhujwe na zinc igaragara neza hamwe na strip substrate.Kubwibyo, kurwanya ruswa kwayo birakomeye.
