Tayada Dahaarka ee la xoojiyey Karistaleynta dusha birta-yar ee birta ah waa labis (sida caadiga ah 1-2 mm dhexroorka), taasoo siinaya aasaas xasilloon oo ku dheggan rinjiga. Tani waxay keenaysaa dusha siman iyo midab midab leh ka dib dahaadhka midabka, taasoo ka dhigaysa mid si gaar ah ugu habboon codsiyada leh baahiyo bilicsan oo sarreeya, sida wejiyada naqshadaha iyo muraayadaha qalabka. Laqabsiga Hagaajinta Hagaajinta Inta lagu jiro hawlaha habaynta-sida foorarsiga iyo shaabadaynta-qaab-dhismeedka yar-yar waxa uu xaqiijiyaa qaybinta isku midka ah ee walbahaarka gudaha. Sidaa darteed, dahaarka zinc wuxuu u nugul yahay dildilaaca ama diirinta, si loo ilaaliyo heerka wax-soo-saarka inta lagu jiro hababka adag ee sameynta biraha. La jaanqaadida Isbeddellada Warshadaha Casriga ah Biraha waaweyn ee galvanized-ka ah ayaa inta badan laga saaray suuqyada waaweyn ee reer galbeedka (Yurub iyo Waqooyiga Ameerika) sababtoo ah joogitaanka walxaha sida rasaasta iyo antimony waxay soo dedejin kartaa daxalka korantada waxayna wax u dhimaysaa iska caabinta cimilada. Taas bedelkeeda, geeddi-socodka-yar-yar-yar ama "eber-spangle" (spangle-free) hababka waa kuwo deegaanka u fiican oo waara, iyaga oo u dejinaya xulashada substrate-ka caadiga ah ee alaabta birta ah ee midabka-dhamaadka sare leh. Fududeynta Dhammaystirka Ka-dib-u-socodka Ka-hortagga Qaybaha-yar-yar waxay mari karaan rogaal-celin toos ah (isku-darka isbarbardhigga iyo heerka xiisadda) si loo sii wanaajiyo dabacsanaanta xaashida iyo saxnaanta cabbirka, si loo buuxiyo shuruudaha adag ee hawlgalka ee saxnaanta sare.
