Milestones in engineered timber construction
Milestones at a glance - from 1849 to the present
Start of a success story
Josef Wiesner registers as a member of the carpenter’s guild of Altheim, Upper Austria.
One step ahead
The carpentry acquires the first mechanized saw and fulfils commissions in the immediate vicinity.
From trade to industry
In 1921 Rudolf and Sebastian Hager take over the business, which from then on is operated under the name "Wiesner-Hager". They expand the company, adding the production of furniture, chairs and tables. Wiesner-Hager becomes the largest manufacturer in this field in Austria and furnishes numerous households, schools, cinemas and concert halls over the coming decades.
A milestone for glued laminated timber construction
Acquisition of a licence to manufacture triangular truss systems and formwork girders (DSB-Dreieckstrebenbau-Träger) as well as expanding engineering prowess propels the company to the next level and serves as the foundation for today’s glulam manufacturing.
From this moment on, roof systems are delivered throughout Austria from the company headquarters in Altheim.
Let's go overseas!
Construction of the Austria Pavilion designed by Gustav Peichl at the World's Fair in New York is designed by our construction engineers and shipped overseas.
Pioneering performance in Klagenfurt
WIEHAG builds the new Klagenfurt Exhibition Hall with a free span of almost 100 metres and a snow load of 200 kg/m2.
With this groundbreaking engineering achievement, the Altheimer company has established itself as a trailblazer in engineered timber construction.
WIEHAG GmbH is founded
Wiesner Hager KG is reorganized into the companies WIEHAG (timber construction, formwork, construction) and Wiesner-Hager furniture.
Dr. Erich Wiesner takes over the management of the WIEHAG Group as a majority owner.
Europe's largest plant for glued laminated timber construction
Major investment in building Europe's most modern plant for glued laminated timber construction using the latest technologies such as automatic sorting according to strength grading and the first CNC pressing jig for beam lengths of up to 50 metres.
Expansion of panel production
Further plant expansion for the manufacture of large-area panels for roof and wall.
From 2001 onwards
Spreading Your Ideas
WIEHAG enters the European arena with large-scale projects and challenges the steel construction sector. In 2001 and 2002, the ice-skating rink in Erfurt and the Neue Messe Karlsruhe were built with the largest engineered timber freespans. Another engineering marvel was Elm Park 2007 - a hybrid construction of wood, glass and steel. In 2010 a multi-storey office building was built in Garmisch-Patenkirchen.
Next Level Engineering:
WIEHAG develops and designs internationally renowned architectural structures such as the Canary Wharf Crossrail Station London (Foster + Partners) and the Macallan Whiskey Distillery Scotland (Rogers Stirk Harbor + Partners)
Grand Prize Dr. Erich Wiesner
Dr. Erich Wiesner is honoured with a lifetime achievement award for his role as head of Europe's leading timber construction company and champion for the timber industry.
