yethu iipilisi zokuthenwa kwezilwanyana inokwenziwa ngentsimbi yeplastiki, ingxubevange yezinc, okanye intsimbi engatyiwa.

le iipilisi zokuthenwa kwezilwanyana eyenziwe ngentsimbi yeplastiki ingabizi, kodwa ayihlali ixesha elide.

iipleyiti zokuthenwa kwezilwanyana ezenziwe nge-zinc alloy azibonakali ziqaqambile, ezinobulukhuni obuhle kunye nokusebenza kakuhle kokuchasana nomhlwa,

iipliers zezilwanyana ezenziwe ngensimbi engenasici zibukeka ziqaqambile, ziqina ngakumbi kwaye zisebenza ngcono kwi-anti-rust kuneepliers zezilwanyana ezenziwe nge-zinc alloy.
