Galvalume Steel Coil (Bobin De Aco Galvalum) ili ndi mawonekedwe onse achitsulo chovimbitsidwa chamalata ndi chitsulo choviika chotentha cha aluminium.Chifukwa chake, pomwe chinsalu chachitsulo choviyitsa chotenthetsera chimagwiritsidwa ntchito, koyilo yachitsulo ya galvalume ingagwiritsidwe ntchito, ndipo imathanso kusintha pang'ono pepala lachitsulo choviyitsa cha aluminiyamu.Iwo ali osiyanasiyana ntchito.
Pankhani ya kupezeka ndi kufunikira, patatha zaka zambiri zakusintha ndi mpikisano wamsika, makampani aku China a galvalume zitsulo akhazikika pang'onopang'ono.Ubale wopezeka pamsika ndi wofunikira ndi wokwanira.Kupanga ndi kugulitsa kumaposa 90% chaka chilichonse, ndipo zinthu zambiri zimatumizidwa kunja chaka chilichonse.
