Kurinda imiyoboro ya galvanised ni ingirakamaro aho umuyoboro ukorerwa hanze cyangwa ugashyirwa ahantu hagwa imvura, ivumbi nubushyuhe. Igice cyo hanze gikozwe mu rupapuro rwicyuma rufite umubyimba utarenze mm 0,5; umuyoboro w'icyuma w'imbere ufite diameter yo hanze ya mm 219 n'ubugari bw'urukuta rwa mm 6-8.
Kubikorwa byinshi byingirakamaro, umuguzi abanza guhitamo umubiri wumuyoboro, hanyuma akemeza niba hakenewe urwego rwimbere rwa galvanis, urwego rwo kubika cyangwa gutwikira byongeye. Kugenzura ibi hakiri kare bituma gupakira no gushiraho urubuga birushaho guhanurwa, cyane cyane iyo ingano nini ya pipine yoherejwe mugice kimwe. Itanga kandi amahugurwa umwanya wo gushiraho bundles kumurongo wumurongo, nikintu gito ariko gifasha abakozi bakora munsi yingengabihe. Niba umuyoboro uzabikwa hanze ibyumweru byinshi, imipira yanyuma hamwe no kurinda imvura yoroshye nayo igomba kwitabwaho.
