Top placings for Donges young welders

Donges SteelTec takes part in the “Jugend schweißt” competition of the DVS Association.

Darmstadt, 02.06.2023. In the preliminary round of the “Jugend schweißt” competition, the trainees of Donges SteelTec GmbH achieved first and third places in the MAG and E-Hand processes. With torch in hand, they were able to demonstrate their manual skills in welding steel sheets. The young Donges welders were rewarded with valuable non-cash prizes and a cash gift. In addition, welding test certificates were issued for the welded fillet welds.

For the first-place winners, it is now on to the next round of the competition at state level in Kassel, and if the welds are perfectly set, then to the national competition in Essen in September. We are already keeping our fingers crossed!

Marco Arndt, responsible for welding training at Donges SteelTec, is proud of the young talent and sees their successful performance as confirmation of the good quality of training at Donges SteelTec.

Steel construction at first hand

Donges SteelTec supports pupils in their career orientation

The practical experience and orientation in the working world of a company is very important for young people on their way to career planning. Against this background, Donges SteelTec again gave boys and girls the opportunity to get to know the world of heavy steel construction on Girls’ & Boys’ Day this year. Nine young people gained their first insights in our technical office, where designers and structural engineers work out the basics for steel structures. After a tour through the individual departments of the company administration, they were finally able to marvel at the heavy, welded steel components for the bridge and building projects in the factory halls.

Donges SteelTec is a training company for construction mechanics and technical system planners. Perhaps the Girls’ and Boys’ Day could contribute to sparking an enthusiasm for building with steel among the young people.

Spectacular assembly of the Jauntal Bridge begins

One of the highest railway bridges in Europe gets a new steel superstructure

At 96 m, the Jauntal Bridge in Austria is one of the highest railway bridges in Europe. In the course of the construction of the new double-track Koralmbahn railway line, the existing single-track structure of the Jauntal Bridge will be upgraded to a modern, double-track steel truss composite structure. Donges SteelTec has been awarded the contract for the manufacture, delivery and assembly of the steel superstructure. The 3300 tonne steel structure will be manufactured at the Darmstadt plant. The 428 m long steel structure will first be assembled in three segments on a pre-assembly area below the existing bridge. The three structural elements are then moved transversely and longitudinally one after the other. In the process, the old and new supporting structures are connected to each other and the existing bridge is also pushed out.

The spectacular assembly work high above the river Drava begins in early January, when the first of the three segments of the new superstructure is first shifted transversely and then coupled to the existing structure. The first longitudinal shift will then follow in February. A technical and logistical challenge for our employees and, after the Danube bridge in Linz (bypass bridges), another milestone for our company in neighbouring Austria.

A successful year comes to an end

Management of Donges SteelTec looks ahead to the new year with confidence

At the last works meeting of the year, Dr Wolf Cornelius thanked all employees for their commitment and successful work in the past business year. Full order books and a correspondingly good presence of the company in the steel construction market allow the management to look positively into the next year. Against this background, the works council and the management agreed in advance on the payment of an inflation compensation to the employees. After so much positive news, the employees celebrated the end of the year in the Christmas-decorated inner courtyard of the company premises. Hot chestnuts, mulled wine and bratwurst from the Donges Grill ensured physical well-being and a good mood until late in the evening.

Donges SteelTec builds new Rhine bridge

Bridge construction division is pleased with major contract for the replacement construction of the Pfaffendorfer Bridge in Koblenz

Donges SteelTec, as part of the ARGE Pfaffendorfer Brücke consortium, has been awarded the contract for the replacement construction of the Pfaffendorfer Bridge in Koblenz.

As an important link across the Rhine, the existing bridge must be completely replaced by a new one. For this purpose, the 311 m long steel composite bridge, which is broken up in the area of the pier coves, will first be built in the lateral position next to the existing bridge and, after the demolition of the existing bridge, will be moved transversely into the final position.

Donges SteelTec is taking over the technical responsibility for the entire structure by preparing the structural analysis of the river bridge, the assembly planning and the execution and workshop drawings within the consortium. Around 5,500 tonnes of steel structure will be manufactured and corrosion-protected in the halls of Donges SteelTec GmbH in Darmstadt. Afterwards, the steel elements, weighing up to 450 tonnes, will be successively transported by ship via a pre-assembly site on the Rhine to the construction site, where they will be assembled above the Rhine by means of floating cranes.

The work for the new Rhine bridge will be carried out between 2023 and 2027

Major order from Salzgitter Flachstahl GmbH

Another milestone in the company history of Donges SteelTec GmbH.

 

Structural engineering division receives major order from Salzgitter Flachstahl GmbH for the construction of a new 63-metre-high production hall. The contract includes the delivery and erection of the primary as well as the secondary steel structure including the building envelope with doors and gates. Drainage, lightning protection and SHEVS are also part of the contract.

Donges SteelTec is preparing the shop drawings and the erection planning. It is planned to erect the 8500 tonne steel structure using conventional lifting assembly. Erection is scheduled to start in mid-2023.

The 183 m long, 46 m wide and 63 m high hall will be equipped over its entire length with a crane runway for two bridge cranes with a load capacity of 500 tonnes each. Due to the partially large distances between the columns, the crane runway girders are designed as open welded profiles with an overall height of 4500 mm.

The entire project is being realised as a joint venture with the company GP Hoch- und Ingenieurbau GmbH, Hanover.

“We are very proud to have been awarded the contract for this forward-looking project. In this new hall construction, we can perfectly combine our know-how and experience from structural steel engineering as well as bridge construction,” says Dr Wolf Cornelius, Managing Director of Donges SteelTec GmbH.

Irene tower Rimbach

Steel ladder to heaven on the Tromm

Donges SteelTec is building the new Irene observation tower on the Tromm for the municipality of Rimbach – a steel construction that resembles a ladder to heaven.

The assembly of the free-standing 34 m high and 50-tonne supporting structure with staircases, landings and railings made of galvanised or coated steel has now begun. An open cladding of wooden beams is being installed on the sides.

The futuristic-looking steel tower is a central component of the newly planned UNESCO Geopark Bergstraße-Odenwald.

Replacement and new bridge construction BAB A73 Bamberg-Lichtenfels

Donges SteelTec moves 1400-ton steel bridge of the motorway A73 into final position

Even storm “Zeynep” and “Antonia” could not stop our technicians: At the end of February, the second superstructure of the motorway bridge in the direction of Bamberg was shifted at the A73 junction Breitengüßbach Süd. The steel structure, which weighs around 1,400 tonnes, is 150 metres long and approx. 18 metres wide, was pushed into its final position over the weekend across the B 4 trunk road, the railway tracks and a field path. Completion of the 3-span steel composite bridge is planned for autumn 2022.
