Muaj plaub yam loj ntawm extruded duab, thiab lawv yog:
1. Khoom.Cov duab no tsis muaj qhov qhib qhib lossis voids (piv txwv li, nqaj, lub kaum sab xis, lossis pas nrig).
2. Hollow.Lawv muaj ib los yog ntau qhov qhib los yog voids (piv txwv li, daim duab plaub los yog square tubes).
3. Semi-Hollow.Lawv muaj voids uas yog ib feem nyob rau hauv (piv txwv li, ib tug "C" channel muaj ib tug nqaim qhov sib txawv).
4. Kev cai Aluminium Extrusion Shapes.Cov duab zoo li no feem ntau muaj ntau yam extrusion. Lawv kuj tuaj yeem yog cov duab sib cuam tshuam nrog ntau yam xim profile. Cov duab no feem ntau yog raws li cov neeg tsim qauv kev qhia tshwj xeeb.
