Intshayelelo: Iisokethi ze-Aluminium zomnqamlezo zidlala indima ebalulekileyo kumzi mveliso wezinto zokwakha kunye nokuhombisa, ngokukodwa kummandla we-scaffolding kunye nezixhobo zayo. Njengecandelo elibalulekileyo, ezi zisoko zibonelela ngezibonelelo ezininzi kunye neempawu ezisebenzayo. Kweli nqaku, siza kuhlola ukubaluleka kweesekethi ze-aluminium zomnqamlezo, ukukhanya kwizibonelelo zabo kunye nokubonelela nge-valuua
