Kuwonetsa katundu:
Mapaipi a aluminiyamu amagawidwa makamaka m'mitundu yotsatirayi.
Malingana ndi mawonekedwe: chitoliro cha square, chitoliro chozungulira, chitoliro cha chitoliro, chitoliro chapadera, chitoliro cha aluminiyamu chapadziko lonse.
Malinga ndi njira extrusion: msokonezo zotayidwa chitoliro ndi wamba extrusion chitoliro.
Malinga ndi kulondola kwake: chitoliro cha aluminiyamu wamba ndi chitoliro cholondola cha aluminiyamu, momwe chitoliro cha aluminiyamu cholondola nthawi zambiri chimayenera kukonzedwanso pambuyo pa extrusion, monga kujambula kozizira, kugudubuza.
Mwa makulidwe: chitoliro cha aluminiyamu wamba ndi chitoliro chochepa cha aluminium.
Magwiridwe: kukana dzimbiri, kulemera kwake.
