Umuyoboro wa galvanised ugizwe ahanini nicyuma fatizo hamwe na zinc. Ibyuma shingiro mubisanzwe ni ibyuma, bitanga imbaraga zidasanzwe no guhindagurika. Ipitingi ya zinc ni igipande cyangwa ibice bya zinc - icyuma gishyizwe hejuru yicyuma cyibanze hifashishijwe amashanyarazi cyangwa ashyushye - uburyo bwo gutwika. Iyi mavuta ntabwo ishimishije muburyo bwiza gusa, ariko cyane cyane, itanga uburyo bwiza bwo kurwanya ruswa, ikongerera cyane igihe cyumurimo wicyuma.
