Si loo hagaajiyo iska caabbinta daxalka, tuubada birta guud (tuubada madow) waa la galvanized.Tuubo bir ah oo la galvanizedwaxaa loo qaybiyaa laba nooc oo ah kuwa lagu shubo kulul ee galvanized iyo kuwa lagu shubo korontada. Lakabka galvanizing-ka kulul ee lagu shubo kulul waa mid qaro weyn, qiimaha lagu shubo korontadana waa mid hooseeya, sidaa darteed waxaa jira tuubooyin bir ah oo galvanized ah. Maalmahan, iyadoo la horumarinayo warshadaha, baahida loo qabo tuubooyinka birta galvanized ayaa sii kordheysa.
Badeecadaha tuubooyinka birta ah ee lagu shubo kuleylka ayaa loo isticmaalay meelo badan, faa'iidada ay leedahay isticmaalka kuleylka ee lagu shubo kuleylka ayaa ah in cimriga ka hortagga daxalka uu dheer yahay. Waxaa si weyn loogu isticmaalaa munaaradda korontada, munaaradda isgaarsiinta, tareenka, ilaalinta waddooyinka, tiirka nalalka waddooyinka, qaybaha badda, qaybaha dhismaha birta, xarumaha kaabayaasha saldhigga, warshadaha iftiinka iwm.
Galvanization-ka kulul ee lagu shubo biyaha waa in marka hore la shiido tuubada birta ah, si looga saaro oksaydhka birta ah ee dusha sare ee tuubada birta ah, ka dib marka la shiido, iyada oo loo marayo xalka amooniyam chloride ama zinc chloride ama amooniyam chloride iyo haanta isku dhafan ee xalka biyaha ee lagu nadiifiyo, ka dibna lagu shubo haanta lagu shubo biyaha kulul. Galvanization-ka kulul ee lagu shubo biyaha kulul wuxuu leeyahay faa'iidooyinka dahaarka isku midka ah, isku dhejinta xooggan iyo cimri dheer oo adeeg ah. Inta badan hababka waqooyiga waxay qaataan habka dib-u-cusboonaysiinta zinc ee tuubada tooska ah ee gariiradda galvanized.
Nolosha tuubooyinka birta ah ee lagu shubo biyaha kulul ee deegaanno kala duwan isku mid ma aha: 13 sano meelaha warshadaha culus, 50 sano oo badweynta ah, 104 sano oo xaafadaha ah, iyo 30 sano oo magaalada ah.
