The Maass family of companies consists of a multinational business conglomerate. All of these companies operate independently of each other, but still work closely as a team. All of the Maass facilities are approved to strict quality control procedures and certified to ISO 9000-2015.

In 1989, under the guidance and direction of René Vilon, Maass Flange & Fitting Canada Inc. was born in London, Ontario. Through continuous growth we have become the leaders in supplying the products we manufacture to the petro-chemical, chemical, refining, pulp & paper, and nuclear industries throughout Canada.

During the years, we have proven ourselves to be successful in providing the services that our loyal customers require. It is this satisfaction from our customers that has empowered our growth to this date. We have continued to specialize in the manufacturing of flanges in stainless steel and other exotic alloys to the highest standards known in the industry. Our capacities range from 1/2 inch through 104 inch nominal pipe sizes and 150 pound through 2,500 pound pressure classes. These sizes are manufactured in accordance to the latest dimensional and material standards. Other standards, such as DIN and other European specifications, can be provided based on customer requirements. Other than flanges, Maass Flange & Fitting Canada Inc. also specializes in supplying butt-weld fittings, high pressure fittings, and other products related to the PVF industry.

As Maass Global was taking shape and becoming amongst the most diversified global flange manufacturers in the world by offering a complete line of material grades; Carbon, Stainless, Duplex, Low Alloy and Special Nickels in both small and large diameter sizes, combined with a full range of pressure classes, in 2015 Maass Flange & Fitting Canada Inc. changed its name to Maass Flange Canada Inc. to become more consistent within the global group.
