Kwimarike yokuhambisa,ixabiso le-aluminium extrusionisekelwe kwi-avareji ye-SMM yemali yosuku.

I-RAYIWELL MFG Limited ngumthengisi oqeqeshiweyo weplate ye-aluminium, iiprofayili ze-aluminium extrusion, kunye neentsimbi zetsimbi ezifana nentsimbi, i-coil yensimbi eyenziwe ngaphambili, i-coil yensimbi ye-Galvalume kunye neentsimbi ze-silicon. IKHAMPANIRAYIWELLBasebenzisane ngokusondeleyo nelitye elikhulu okanye elincinci e-China ngexabiso elihle kunye nexesha lokuhambisa elikhawulezayo kumgangatho ophezulu kubathengi bethu abafana nawe.
