I-Shingfong pvc trunking ikumgangatho ophezulu, inoluhlu olubanzi lwe-pvc duct, ngaphezulu kwe-200 yobukhulu obahlukeneyo kunye nobukhulu, sinokunikezela ngombala owenziwe ngokwezifiso we-pvc trunking. Ukuze kube lula ukufaka i-pvc duct, ngokuqhelekileyo siya kubeka i-tape yokubambelela ubukhulu obuphindwe kabini ngasemva kwe-pvc trunking. Imarike eyahlukeneyo inemodeli yayo yokuthengisa eshushu ye-pvc trunking encamathelayo. Umzekelo, enye imakethi ithanda i-pvc trunking kwiibhokisi ezipakishwayo, ezinombala omtsha oncamathelayo oluhlaza, abanye bathanda i-pvc trunking encamathele ebomvu-mnyama. Sineteyiphu encamathelayo ekumgangatho ophezulu wokunikezela.
