Angerbach Bridge for the A44 near Ratingen

The newly built Autobahn section of the A44 from the interchange with the A3 (Ratingen-Ost) and the junction with the B227 in Velbert is one of the major projects to close a gap in the motorway network in North Rhine-Westphalia. The new section stretches over a distance of approx. 9 kilometers and includes building a total of five bridges. The bridge over the Anger valley is the longest of all five with a span of about 386 meters. It will be made of 4,500 tons of heavy plates produced by Ilsenburger Grobblech.

The Second Strelasund Crossing

The second crossing over the Strelasund or Strela Sound is one of the longest bridges in Germany. The core piece consists of six subsections joined to connect the island of Rügen close to Altefähr with Stralsund on the main land. Two lanes plus an additional third lane opened if traffic requires to do so run parallel to the old dam leading to the island.

The Ziegelgrabenbrücke is the most impressive part of the building. We delivered around 3.000 tons of heavy plates, amongst other to build the pillar.

Rion Antirion Bridge

The suspension bridge named after the former Greek state premier Harilaos Trikoupis connects the western Greek mainland near Patras with the Peloponnese peninsular. With its length of 2,500 meters it is one of the longest bridges worldwide. Instead of a 40-minute ferry transfer, it now only takes five minutes to make the crossing. Due to its particular location, the building is designed to withstand earthquakes with forces of 7.5 on the Richter scale.
Around 9,000 tons of sheets from Ilsenburg were used to build this suspension Bridge.


Bertelsmann Pavilion

The Bertelsmann pavilion at the EXPO-Plaza in Hanover consists of two building sections: a square block and an amorphous round body, the "Planet m".

The round section of the building rests on six pillars at a height of 9 meters above the EXPO-Plaza. It is 46 meters long, 36 meters wide and 24 meters high. To build this complex steel construction, we supplied approximately 5,000 tons of grade API 2W Gr. 50 and API 5L Gr. X52 heavy plates.

Exhibition Hall 9 in Hannover

With its length of 135 meters and a width of 238 meters, hall 9 on the Hanover fair grounds is the largest unsupported exhibition hall in Europe.  

The roofed area of the pillar-free area amounts to 32,000 square meters corresponding to a little more than three football pitches. The roof consists of a glass-steel-wood construction containing 2,400 tons of profiles and heavy plate
