About Us

The MAASS GLOBAL GROUP is a global specialist in open die, closed die and ring rolling products in all available material grades. We are 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.

The roots trace back to the 1940's, where the "Wilhelm Maass Flanschenfabrik GmbH" was founded in Essen, Germany. During the late 1970's and through the early 1980's the Maass family opened additional facilities in The Netherlands and the UK for their domestic markets and international sales. Soon thereafter, in 1982 Maass Flange Corporation in Houston, Texas was formed, today possibly being the group´s largest production facility. In the late 1980's the company further expanded its flange and fitting manufacturing and distribution of flanges and related products into Ontario, Canada.

In 1992, the Maass family opened its first Mexican manufacturing plant, located in Acuna and a sales office in Mexico City for the distribution of flanges, fittings, pipe and valves. Since 2006 we incorporated our own forging and machine manufacturer in Pune, India and recently we have successfully opened our commercial trading enterprise in Singapore.

Today, we have not only established ourselves with the help of our customers to be an international player, however also bringing a quality product accepted by all major international governing bodies such as Exxon, Shell and Norsok, just to name a few to your clients.

We hope you enjoyed your experience with Maass Global Group and look forward to your continued business !!
