Marka mitirka birta birta ah ee birta ah, xulashada birta, sida caadiga ah tixgelinta ugu weyni waa: sifooyinka farsamada (xoogga, adkaanta, iwm.), waxqabadka iyo kharashka.Laakiin qaybaha galvanized, ka kooban xulashada alaabta, tayada galvanizing-kuleylku waxay leedahay saameyn weyn.

Mid ka mid ah daxalka ee habka ka hortagga daxalka birta galvanized noocyo kala duwan oo deegaanka ah laakiin waa in fiiro gaar ah si ay u isticmaalka sifooyinka, ku dhowaad dhammaan birta ku haboon galvanizing kulul-muquufin, sida kulul-rogid, bir qabow-duubay, birta tuuray, birta been abuurka ah, alaabta birta ah ee la shubay sida birta, inta badan ka hortagga daxalka waxay noqon kartaa hab galvanizing kulul, si loo horumariyo nolosha.

Tiro ayaa la isticmaalay kaarboonka caadiga ah iyo daawaha hoose ee xoogga sare ee dhismaha birta galvanized alaabta ugu caansan.Si kastaba ha ahaatee, maaddooyinka ugu muhiimsan ee kiimikada si loo helo lakabka galvanized ee ugu fiican ee walxaha birta ah waa: kaarboonka ≤0.25%, maadada fosfooraska ≤0.04%, maadada manganese ≤1.35%, content silicon ≤0.03% ama 0.15% ~ 0.25 % (0.03% 0.15% luminta birta rabshadaha leh, maqaarka madow ee shaqada, diirka).Sida iska cad, ma aha dhammaan kaarboonka caadiga ah iyo birta qaab-dhismeed ee hooseeya ee-hooseeya inay buuxiyaan shuruudaha kala duwanaanshahan ka kooban.
