1, kharashyada daawaynta hooseeya: kharashka ka hortagga miridhku galvanized kulul waa ka hooseeya qiimaha daahan kale rinjiga;
2, waara: kulul-maquufinbar xagasha birta galvanizedwaxa uu leeyahay sifooyinka dhalaalaysa dusha sare, lakabka zinc labis ah, ma dahaadh ka daataan, dhibic lahayn, adhesion xoog leh, iska caabin daxalka xoog leh, deegaanka ku hareeraysan, heerka caadiga ah kulul-muquufin galvanized dhumucdiisuna waxay ka hortagtaa miridhku waxaa lagu hayn karaa in ka badan 50 sano dayactir la'aan; Magaalooyinka ama meelaha xeebaha ah, lakabka caadiga ah ee kuleylka kuleylka leh ee ka hortagga miridhku waxa lagu hayn karaa 20 sano iyada oo aan la hagaajin;
3, isku halaynta wanaagsan: lakabka galvanized iyo birta waa isku-dhafka birta ah, waxay noqdaan qayb ka mid ah dusha birta, sidaas darteed cimri dhererka dahaarka waa la isku halleyn karaa;
