Kubijyanye no kubumba ibicuruzwa dufite ubwoko bubiri bwibicuruzwa, aribwo ubushyuhe bwo kugabanya insinga zanyuma hamwe nubushyuhe bwo kugabanya insinga. Ubushyuhe bwo kugabanya umugozi wanyuma watewe inshinge hamwe na polyolefine kandi ifite UV hamwe no kurwanya abrasion. Amashanyarazi ashyushye ashyizwe muburyo bwa spiral imbere yigituba, bitanga uburyo bwizewe butarinda amazi kandi bukingira kubutaka bwaciwe ninsinga cyangwa insinga zuzuye umwuka. Ubushyuhe bwo kugabanya ubushyuhe, bukozwe nibikoresho bishyushye bishushe hamwe na polyolefin ihuza ibice, kandi bifite imikorere myiza yo gufunga, kurinda bikoreshwa cyane cyane mukwikingira no gufunga kumashanyarazi yumuriro muto.
