Taa, ọkpọkọ ígwè galvanized nwere nnukwu ahịa ahịa kwa afọ na ahịa ígwè. N'ihi teknụzụ nhazi mmepụta, a na-ekewa ọkpọkọ galvanized n'ụdị abụọ: ọkpọkọ electro galvanized na ọkpọkọ na-ekpo ọkụ. Na ndụ, a na-ejikarị ndị mmadụ na-akpọ ọkpọkọ galvanized nke na-ekpo ọkụ dị ka ọkpọkọ galvanized. N'ikwu okwu n'ụzọ dị mfe, ọkpọkọ galvanized na-ekpo ọkụ nwere uru arụmọrụ karịa ọkpọkọ galvanized electro. E wezụga nke ahụ, n'ihi ọnụ ahịa nhazi dị elu, ọnụahịa ígwè ígwè dị ntakịrị ọnụ karịa nke electro galvanized pipe. Dị ka a na-achị, mgbe atụnyere na-ekpo ọkụ tinye galvanized ígwè ọkpọkọ, akụkụ anọ ígwè ọkpọkọ nwere bụghị otú ezi ihe onwunwe na dum, karịsịa ihe onwunwe nke corrosion eguzogide. N'ime afọ ndị na-adịbeghị anya, n'ihi amụma mba, a kpochapụrụ ọkpọkọ electro galvanized n'ahịa nchara.
Mgbe a bịara na ọkpọkọ galvanized, anyị ga-ama banyere okwu ahụ bụ "galvanization". Hot tinye galvanized ígwè anwụrụ ga-mere nhazi ebe a ga-guzobere a oyi akwa nke alloy gburugburu ọkpọkọ n'ihi anụ ahụ mmeghachi omume n'etiti gbazee zinc na ígwè. N'ihi ya, ụdị ọkpọkọ a nwere nguzogide corrosion siri ike karịa ụdị ndị ọzọ a na-ahụkarị. Tụkwasị na nke ahụ, ọkpọkọ ígwè ahụ nwere mkpuchi dị nnọọ mma na ihe onwunwe adhesion siri ike nke oyi akwa zinc ka ọ na-agbatị ndụ ọrụ nke ọkpọkọ. Ọzọkwa, ma e jiri ya tụnyere ọkpọkọ ndị ọzọ na-emekarị, ọkpọkọ ígwè galvanized na-ekpo ọkụ nwere ọtụtụ uru doro anya na ọtụtụ ebumnuche n'ezie na ndụ.
N'ikwu okwu na teknụzụ, galvanization metụtara itinye ihe mkpuchi zinc na-echebe na ahụ ígwè ma ọ bụ ígwè, iji gbochie nchara. Galvanization nke na-ekpo ọkụ bụ ụzọ a na-ejikarị eme galvanization, nke a na-emikpu ozu ọkpọkọ n'ime bat nke zinc gbazere. N'ozuzu, dị ka akụrụngwa nke ọkpọkọ, galvanized ọkpọkọ nwere abụọ edemede: pre galvanized ọkpọkọ na-ekpo ọkụ tinye galvanized ígwè ọkpọkọ. Ọkpụkpọ nke mbụ galvanized na-ezo aka na ọkpọkọ welded bụ nke mebiela, iwepụ nchara, phosphoriization, na ihicha usoro tupu galvanization.
