1966   Georg Stemeseder laid down the foundation stone for today´s company in Hallein, Austria. His new company focused on the takeover of distribution agencies in the Austrian market and expanded to two employees in 1967.

1968   the company had grown to ten employees; it now has 170.

1995   In the 1990s, a lack of space led to the decision to construct a new company building. In 1994 the company moved into its new, architecturally appealing building in Hof near Salzburg.
When Austria joined the European Union, the company’s business relationships began to change and important decisions had to be taken: The development of protection systems for wooden windows made from aluminum heralded a new era in the company. The innovative products were presented for the first time at the “BAU 99” exhibition in Munich, and the high levels of demand in the market led to rapid growth.

1999   1999 together with Mr. Johann Itzlinger, Mr. Eng. Edgar Stemeseder assumed executive management of the company. The original distribution business was restructured.

2007   To increase the quality of the products and to improve the levels of flexibility, in the year 2007 the decision was taken to invest in the company´s manufacturing business.

2008  the new manufacturing systems went into operation. The company was thus able to draw on the latest powder coating systems and welding systems.

2010   Due to the rapid rates of growth the existing levels of capacity quickly hit their limits and the operations were extended once again in the year 2010. In addition to further capacity, new production lines for aluminum front doors, door panels and aluminum facings for front doors were also established
Today, the company G.S. Georg Stemeseder GmbH is also a designer of systems for aluminum front doors, aluminum facings, and door panels.

2015   The company has also risen to the challenge of becoming an international business and has established itself on the European market with success.
