Platt has a wide selection of electrical and related materials. Their service is top notch. If you can't find what you are looking for on Platt's website, just call and ask about the specific items. Their suppliers often provide Platt with very detailed catalogs on a specific category. I have never needed neon manufacturing supplies.
Because of work, I order and pick-up materials from Platt often. But I don't believe they deal in materials specifically for Neon sign manufacturing, if that is what you're asking for. They deal in electrical parts, such as lighting ballasts, Romex wiring, CAT 5/6 tele/data cable, electrical conduits of all types, wiring for over head power lines, motor control components, etc. As for a catalog, you can check them out at platt.com to see if they might have what you need.
