There was a time when all of the material that came through our flange shop was domestic to the United States. However, in today’s competitive marketplace, we would almost be doing you a disservice not to give you an option of finding less expensive alternatives to some domestic material. Insert flanges are one of the few flanges left where most of them are still made from domestic material. However, on occasion, we do manufacture insert flanges out of foreign material. If you require that all material must be domestic, simply state this at the time of quotation. American Insert Flange prides ourselves in flexibility and doing our best to meet your pricing and quality needs.
