Appleton Stainless, Inc. opened its doors in April of 1999. Through our distribution partners, we supply pipe, tube, fittings and valves to such industries as food and dairy, biopharmaceutical, wastewater, ethanol, meat packing, pulp and paper, 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, polished pipe and tube, 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 distributors stainless needs.

As the industries changed, we have evolved, adjusting our focus to remain effective in the market place. Starting 1999 in a small warehouse in central Appleton, in 2001 we moved to a larger facility in Appleton’s Northeast Industrial Park.  Outgrowing that space, we moved to our current facility on Appleton’s Northwest side to further expand our inventory of polished pipe and tube in sizes up to 20”. 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;  If you require it sooner – ask!!  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. Yet we are large enough to handle small to medium sized projects with confidence. 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.
