Iithayile zofikelelo olunyusiweyo, ezikwaziwa njengomgangatho wofikelelo onyusiweyo okanye {0}umgangatho ongashukumiyo, yinkqubo yomgangatho eyilelwe ngokukodwa iindawo ezifuna iimeko ezizodwa zokusingqongileyo.
Inqaku layo eliphambili kukudala indawo ephakamileyo phantsi komgangatho. Esi sithuba asikho nje ukuququzelela umzila kunye nolawulo lweentambo ezahlukeneyo kodwa kwakhona siphucula ngokufanelekileyo umoya kunye nokutshatyalaliswa kobushushu bomgangatho.
Iithayile zomgangatho wofikelelo onyusiweyo ngokuqhelekileyo ziquka izixhaso, imiqadi, kunye neepaneli. Iipaneli ziza kwizinto ezahlukeneyo, ezibandakanya kodwa zingaphelelanga kwi-PVC, intsimbi, kunye ne-aluminium alloy, nganye ineempawu zayo ezizodwa kunye nokusetyenziswa.
