About Us

The The MAASS GLOBAL GROUP is a multinational business conglomerate of manufacturing plants, offices and stockists around the world.

Our 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 being the groupĀ“s largest production facility. In the late 1980's the company further expanded its distribution and manufacturing of flanges and fittings 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 manufacturing plant in Pune, India. In addition, the The MAASS GLOBAL GROUP opened sales offices in Singapore, Dubai and Shanghai to provide faster, more efficient and personalized service to its customers in the region.

In 2015, the The MAASS GLOBAL GROUP added a new division to its group; Maass Special Alloys Nederland BV. Complete piping packages (pipes, fittings, flanges etc.) in Special Stainless and Nickel Alloys can be supplied from our extensive network of reputed manufacturers and distributors.
