Zeman Group – Success built on innovation, quality and tradition

Since the founding of Zeman & Co GmbH in 1965, companies with more than 300 years of experience in steel construction have come together under the umbrella of the Zeman Group. It is pioneers and constants in the industry that make up the success of the Zeman Group. Since the very beginning, the Zeman Group has operated sustainably, consolidated its position through innovations in mechanical engineering and expanded with foresight. The fruits of success are harvested at the right time and invested in further sustainable growth. This is the secure basis on which our customers can rely.


First constructions under a flying roof and open sky

In 1965, Hans Zeman and his partners founded the company Zeman & Co for the production of steel constructions. The first constructions were initially manufactured under a flying roof and in the open air, before the first own factory hall was built in Scheifling, Styria, in 1966.


Gavle trapezoidal profile procurement

By sourcing trapezoidal profiles from the Swedish Gavle Verken, Zeman & Co was able to erect hall buildings of higher quality, which greatly expanded the business field and the range of products. In 1969 and 1971 the Zeman & Co factory was expanded.


United Aluminium Plant Ranshofen

This order with a volume of more than 12 million Schillings caused an enormous growth spurt. The expansion of the company’s own production halls created the capacity to handle further large orders for General Motors, BMW and the Dürnrohr and Mellach district heating power stations.


Launch of our own trapezoidal profile production

With the founding of Austroprofil, the Austrian market leader for the production of trapezoidal profiles was established. The adaptation of the mechanical equipment also laid the foundation for Zeman-Maschinenbau.


Zeman & Co goes international

Zeman & Co took its first international steps to Saudi Arabia with the export of fully air-conditioned prefabricated houses. Further contacts in Jordan and Iraq were followed by major orders for the construction of turnkey cold storage houses and cattle farms.


Development of the LEGATO arch system

With the development of the arch roll former and its worldwide patenting, another innovative step was taken. The trapezoidal sheet metal arches represented a new architectural and construction element that enabled Zeman to open up the European market.
In addition to successful application in Austria, the LEGATO arch system is marketed within Europe via licence agreements. Zeman’s mechanical engineering division produced and exported the machines. The first customer was the Finnish company Rannila in 1988, further exports went to Germany and Portugal, among others, and later also to the Czech Republic, Italy and Russia.


European Steel Design Award

The first internationally sensational award for Zeman & Co, the European Steel Design Award, was presented for the “El Dorado” truss pyramid in Vösendorf, built in 1982. This project crowned a series of highly interesting projects realised in Austria.

First company foundation abroad

Immediately after the fall of the Berlin Wall, the Florprofile company was founded in Poland, marking the opening of the company group to the East. Equipped with the most modern roll formers and systems for the production of profiled sheet from its own machine production, Florprofile was able to contribute significantly to the success of the group of companies over many years.


Worldwide innovation: fully automated production of SIN corrugated web beams

Zeman was the first company in the world to develop a fully automated production line for welded sheet metal beams with a sinusoidally corrugated web. Order volumes of several 1000 tonnes became possible for the Zeman Group thanks to the increase in production efficiency. From then on, SIN corrugated beams were increasingly and successfully used in all areas of steel construction.

Machines made by Zeman became an export hit. The first machines for the production of SIN corrugated web beams were sold to Montana in Switzerland, Thyssen in Germany and others to Usinor in France, among others. Machines for the LEGATO arch system also sold worldwide.


Further company foundations, expansion of the Group’s own production capacities and export hits

From 1990-1992, the companies KOVOVE profily in the Czech Republic, as a supplier of trapezoidal sheet metal and roof and wall cladding, and the project company Zeman HDF in Poland, which is now considered the specialist for high-quality steel construction in Poland, were founded. In addition, the company GZP was founded, which has made a name for itself with the production of steel structures.
Zeman also built a new hall for its mechanical engineering division, Zeman Bauelemente. As a result, machinery exports went to the Codeme company in Brazil, and later to Turkey, Russia, Ukraine and China. Through its presence at trade fairs in the USA from 1998 and later also in Russia and other countries, Zeman machines were able to convince customers on all continents.


Expansion through integration of further companies into the Zeman Group

With the complete takeover of the international hall construction specialist PEM Buildings and the friendly integration into the Zeman Group, the steel construction project business was successfully expanded from England via the Urals to China.


European Steel Design Award

Zeman & Co received the second European Steel Design Award for the “Airport Tower” project at Vienna-Schwechat Airport. For this project, Zeman & Co built a steel structure for an oversized projection screen onto which a translucent membrane is stretched. The assembly platform was built with SIN corrugated web girders. It was the largest membrane structure in Austria in 2005.

European Steel Design Award

European Steel Design Award for Waagner Biro steel and glass, Zeman HDF and Zeman & Co for the atrium roof of the “Zlote Tarasy” (Golden Terraces), an office, entertainment and shopping centre in Warsaw.

Like a cloth draped over seven spheres – this is the image that the impressive architecture of steel and glass evokes in the viewer of the multifunctional building in the heart of Warsaw. At around 10,000 m², the geometrically complex grid shell is a huge free-form space. Triangular glass panes ensure the greatest possible flexibility in the design of the curvature. For the construction of the steel nodes, Waagner-Biro developed the technology that was already used in the construction of the roof of the Great Court in the British Museum. The use of this innovative technology resulted in an architectural landmark that is unique in its elegance throughout the country.

New foundation of the company Zekon Spolka z o. o.

Zekon is the new production facility that emerged from GZP, a company that has existed for 15 years. The company’s main area of activity is the production of steel structures for industrial and warehouse halls, sports facilities and shopping centres, as well as for the energy and petrochemical sectors.
Zekon has a modern and automated production line for the manufacture of straight and convergent corrugated web beams SIN, which have been in great demand in recent years due to their relatively low weight and price compared to welded hot rolled sections and lattice structures.
Zekon uses software invented by the Belgian company SCIA for the automatic control of production lines and numerical machines. This software is integrated with steel construction software such as BOCAD, AUTOCAD, STEELFAB and HYPESTEEL.

European Steel Design Award

European Steel Design Award for Waagner Biro steel and glass and Zeman HDF for the Baku Airport toll booth.

The elliptical entrance arch with a width of just over 72 and a depth of 28 metres welcomes visitors to Baku Airport both on arrival by road and in the air. To emphasise the geometric shape, the structure is supported by only two concrete foundations. The smooth architecture of the arch is accentuated by a clear interface at the support points of the concrete base on which it sits, to ensure a smooth transition from the arch to the ground
The arch consists of a steel structure supporting a cable net arrangement, which in turn supports the row of suspended gold-coloured perforated panels. To ensure efficient construction time, the tubes and steel plates that make up the main structural ring and support frame, respectively, were prefabricated off-site using special customised moulds.

European Steel Design Award for the roofing of the historic Salzburg Main Station

European Steel Design Award for Zeman & Cofor the roofing of the historic Salzburg main station.

The platform at the main building has its own listed roof, which was restored by Zeman & Co GmbH in the course of the conversion work. The over 100-year-old listed barrel roofs were restored and integrated into the new overall roof in such a way that they remain architecturally and statically independent.
For this purpose, the still riveted construction of the barrel roofs was dismantled by Zeman into thousands of individual parts, transported to the factory, refurbished there and then – according to the requirements of the new building – rebuilt somewhat offset. This historic construction was then integrated into the new platform roofs. Although the new roof structure has spans of up to 52 metres, the slender construction nestles up against the barrel roofs without touching them.
Thanks to the innovative fire protection concept, which took into account the melting out of the plastic membrane in case of fire, the strict fire protection specifications could be met without additional fire protection measures at comparatively low costs. The extensive construction work was carried out while the station was in full operation.
