American Insert Flange makes the majority of our products in our machining facility in New Jersey. We also have a network of machine shops that we use for certain types of flanges. For example, some customers need our bolting rings to be hot-dipped galvanized, so we send the bolting rings out to one of our certified suppliers and have this process done. AIF runs a creative an innovative machine shop that helps provide you with the best possible product, at the best possible price, in the shortest amount of time.(and we still make the majority of our products in-house!)
