1, Kharashka daawaynta oo hooseeya: Qiimaha dhuujinta kululbar xagasha birta galvanizedka-hortagga ayaa ka hooseeya qiimaha dahaarka kale ee rinjiga;
2, waara: kulul-muquufin galvanized birta birta leh sifooyinka dhalaalaysa dusha sare, lakabka Zinc uniform, dahaadhayn lahayn, dhibicyo lahayn, adhesion xoog leh, iska caabin daxalka xoog leh, deegaanka ku hareeraysan, heerka caadiga ah kulul-muquufin galvanized dhumucdiisuna waxay noqon kartaa 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;
