On October 16, 1854, the Vienna city magistrate granted Rudolph Philipp Waagner an "Iron trade authorisation". That same year, Anton Biró and Albert Milde & Co. merged. The company first used the name Waagner-Biro in 1924.
In 1906, the company provided the Vienna State Opera with stage equipment. Forty years later, the company rebuilt the opera house's roof. Other roof projects include Vienna's Stephansdom in 1948, the Munich Olympic facilities in 1969, the Prater Stadium in Vienna in 1985, and the Reichstag dome in Berlin, for which the company won a European Steel Design award in 1999. Waagner-Biro won another award in 2003 for the British Museum's Queen Elizabeth II Great Court.
Between 1910 and 1932, the company completed Schweden Bridge, Floridsdorf Bridge, Frieden Bridge, Augarten Bridge, and other bridges in Vienna. Other bridges built by Waagner-Biro include Europa Bridge in Innsbruck, Austria in 1962, North Bridge in Vienna in 1964, and bridges over the Danube River in the Vienna districts of Floridsdorf in 1979 and Brigittenau in 1980.
In 1982, the Dubai branch office opened. In 2000, Waagner-Biro Gulf LLC was established.
