SCH40 GI tubbada birta ah ee cidhifyada goglan waxa loola jeedaa tuubo bir ah oo la soo saaray si ay u buuxiso heerka SCH40 ee dhumucda gidaarka oo ka samaysan bir galvanized ah. "GI" waxay u taagan tahay "birta galvanized" oo muujinaysa in tuubada lagu dahaadhay lakabka zinc si looga ilaaliyo daxalka.
Erayga "darafyada jeexjeexan" ayaa tilmaamaya in cidhifyada tuubooyinka lagu nashqadeeyay jeexjeexyo si ay u fududeeyaan rakibidda isku-xidhka farsamada ama qalabyada. Cidhifyada jeexjeexan waxaa caadi ahaan loo adeegsadaa nidaamyada ilaalinta dabka, nidaamyada HVAC, iyo codsiyada kale halka loo baahan yahay xiriiryo sugan oo degdeg ah.
