Murakaza neza kumurongo ushimishije wimikorere yumuryango ikozwe mubikoresho byiza bya zinc alloy material.Inzugi zumuryango ntabwo zikora gusa ahubwo zisohora umwuka wubwiza nubwiza, bigatuma wiyongera neza imbere imbere.
Kumenyekanisha ibikoresho byacu byiza kandi byujuje ubuziranenge byumuryango, bikozwe mubikoresho byiza bya zinc.Iyi ntoki nziza cyane yerekana ubwiza nubwiza, ikongeraho gukoraho ubwami kumuryango uwo ariwo wose.
