Appleton Stainless, Inc. opened its doors in April of 1999. We supply pipe, tube, fittings and valves to industrial customers that include manufacturers, other PVF distributors, and contractors in such industries as pulp and paper, biopharmaceutical, wastewater, ethanol, meat packing, dairy, power plants, semiconductor and mining.

Originally focused on the custom manufacture of stainless pipe/tube fittings, ASI has evolved into a stocking manufacturer of 45° laterals, reducing tees, custom reducers and many other unique or difficult to find piping products. We have coupled that with an inventory of more mainstream fittings to provide one-stop procurement for many of our customers' stainless needs.

Starting in a small warehouse in central Appleton, ASI has grown to its current facility in Appleton's Northeast Industrial Park where we offer our customers many specialty fittings, flanges, fabrication and custom machining with a heavy focus on fast turnaround. Our normal turnaround on most custom fittings is 5-7 working days, and needing it sooner doesn't have to mean tripling the price. We work with customers to find the solution that best fits the circumstance, be it air freight, expedited delivery, special packaging or other needs.

At ASI, you will find a company that is small enough to be nimble-adjusting shop schedules to adhere to the most demanding of customers' lead-time requirements. Our shop is structured for the expedience and efficiency you must have, while keeping the price competitive. With our focus on fast turnaround, you and your customer enjoy the peace of mind that we will have your fittings done on time and shipped when you want.
