Ibyiza bya coilvanisile: ifite imbaraga zo kurwanya ruswa.Irashobora gukumira ubuso bwicyuma cyangirika kandi ikongerera igihe cyakazi.Byongeye kandi, umuzingo wa galvanised urasa neza cyane, mwiza kandi mwiza
Ibyiza: ubuso bufite imbaraga zo kurwanya okiside, ishobora gushimangira kurwanya ruswa hamwe nubushobozi bwo kwinjira mubice.
Igiceri cya galvanised gikoreshwa cyane cyane mu guhumeka, firigo no mu zindi nganda.
Kurugero, isahani yinyuma yikigo cyimbere cyumuyaga, icyapa cyinyuma cyinama y'abaminisitiri, ibice by'imbere, hamwe na shell hamwe n'imbere mu gice cyo hanze byose bikozwe mubyuma.Ibidukikije bikora muri ibi bice bizahura nuburyo bukomeye bwa okiside nkimvura, urumuri rwizuba hamwe na ruswa yangirika, bityo ibishishwa bikoreshwa cyane.Ifite uruhare runini mubuzima bwuruganda nubuzima bwumuryango.
