Hi, We are looking to start up a Car aluminium radiator manufacturing company. Can you please suggest us the tubes for the radiators. I believe that the width of the tube is 1 inch, OD is 4mm and tube wall thickness is 0.5mm. Can you let us know the cost details of the tubes? Please suggest us few alternate tubes which are best used by the other aluminium radiator manufacturers across the world. Also let us know if you have branches in India.
