Icyuma gikonjesha gishobora kugabanywamo icyuma cya aluminium zinc cyometseho icyuma (icyuma cya galvalume), icyuma cyometseho icyuma hamwe nicyuma cya aluminiyumu ukurikije ibyuma bitandukanye.
Urupapuro rwicyuma rushyutswe ni ubukonje-buzengurutswe bukomeza gushyuha-urupapuro rwicyuma kandi rukaba rufite umubyimba wa 0.25 ~ 2.5mm.Ikoreshwa cyane mubwubatsi, gupakira, ibinyabiziga bya gari ya moshi, gukora imashini zubuhinzi, ibikenerwa buri munsi nizindi nganda.
Urupapuro rwicyuma rushyutswe kandi rwitwa urupapuro rwa galvanised cyangwa urupapuro rwera: ni ubwoko bwimbeho ikonje ikomeza gushyuha-shyira urupapuro hamwe nuburinganire, hamwe nubunini bwa 0.25 ~ 2.5mm.Ubuso bwa plaque yicyuma ni bwiza, bufite imirongo ifunze cyangwa amababi ya zinc.Ipine ya zinc irakomeye kandi irwanya kwangirika kwikirere.Mugihe kimwe, isahani yicyuma ifite imikorere myiza yo gusudira hamwe nubukonje bukonje.Ugereranije nurupapuro rwicyuma, urwego rwicyuma rushyushye rwicyuma rushyushye cyane, rukoreshwa cyane mubice bisaba kurwanya ruswa ikomeye.Urupapuro rwa Galvanised rukoreshwa cyane mubwubatsi, gupakira, ibinyabiziga bya gari ya moshi, gukora imashini zikoreshwa mu buhinzi n'ibikenerwa buri munsi.
Ubugari ntarengwa bwibisahani byometse kumiterere yicyuma ni 600 ~ 1800mm, naho uburebure bwibanze ni 2.5, 3.0, 3.5, 4.0, 4.5, 5.0, 5.5, 6.0, 7.0, 8.0mm.Ubugari: 600 ~ 1800mm, amanota 50mm.Uburebure: 2000 ~ 12000 mm, amanota ukurikije mm 100.
