Eyona ngongoma ibalulekileyo kwiukugoba ukusetyenzwayeeprofayili ze-aluminium yezoshishino kukuba nemizobo ethile yokucubungula, ukuze sikwazi ukucubungula ngokwemizobo. Ngenxa yokuba ukugoba kucutshungulwa kwi-angle, ukuba ukugoba kwenziwa kwii-angles ezahlukeneyo, umphumo uya kuhluka. Abanye abantu baya kuba nexhala, emva kweiprofayile ye-aluminium yemizi-mvelisoigobile, ngaba kuya kubakho imigca okanye imibimbi kwindawo egobayo? Enyanisweni, akukho mfuneko yakuzikhathaza kakhulu ngale nto. Ukujonga kumatyala okusebenza, oku akwenzeki.Emva kokugoba,Iiprofayili ze-aluminiumzisetyenziswa kakhulu kwisixhobo sokuhambisa umgca, njengemigca yokuhambisa ukutya, imigca yokuhambisa, njalo njalo. Iiprofayili ze-aluminiyam ezigobileyo zingasetyenziselwa ukwakha isakhelo ukuba nje sithuthwa nge-engile.
