At the heart of our new technology: New construction and reconstruction right on schedule
Whether it be maintenance, scheduled upkeep or unplanned damage, Slab production specialists are the central point of contact for the fitness of the production lines. In order to be able to optimally meet the mechanical repair requirements of the new electrical steelmaking plant, extensive new construction and revamping work is being carried out at BTA in Building 52 at voestalpine in Linz. The aim of voestalpine is to create a central location for the maintenance teams in the immediate vicinity of the steelmaking plant. The beginning of construction of the production building extension has been completed, and the overall construction project is right on schedule.
More space for modern maintenance
The fact that everything has been running smoothly so far is due to precise planning, teamwork and close cooperation. All of the project work is being carried out during ongoing operations and in parallel with other projects. Workshop capacity is being expanded in order to be able to integrate the new areas and tasks into the existing activities in Building 52. The mechanical wing in the existing Building 52 is being extended by roughly 650 m² to include a modern maintenance strategy. The on-call services in five-shift operation as well as repair, control and maintenance teams in day shift and two-shift operations are being accommodated.
Several construction sites, one objective.
Before the building could be extended, the hydraulic room and the existing gas cylinder storage had to be demolished and rebuilt. Es wurde weiter nördlich inklusive Verbindungsgang zwischen dem neuen Werkstätten-Trakt und dem neu errichteten Stiegenhaus wieder aufgebaut. Additional parking space has been installed on the north side in front of the workshop for the fleet of BTA emergency vehicles so that teams can be on site as quickly as possible. The heavy-duty road west of the extension as well as the seepage troughs and splash guard fence have already been relocated and adapted. The massive construction work around the building foundations and collision protection of the steel structures was completed in April 2025.
Verbindungen schaffen: Tradition meets innovation
The fact that voestalpine combines tried and tested methods with new ways of doing things, employs highly skilled people and uses state-of-the-art technologies is very evident in the workshop expansion. Zwischen den beiden neuen Gebäuden BG52 und BG53 wurde ein Verbindungsgang, der sogenannte Skywalk, zur sicheren Querung der Bahngleise und der Schwerlaststraße für den Schlackentransport errichtet. Zusätzlich entsteht einen Laufsteg zwischen einem anderen bestehenden Skywalk (LD3 / BG19 / Trafogebäude) und dem ostseitigen Werkstättentrakt BG52. The new construction and reconstruction focus not only to purely technical innovations but on the wishes and needs of the people who work in production. The modern workshop areas offer sufficient space and a pleasant working atmosphere. Thanks to the new skywalk, employees can quickly and safely enter and exit the buildings that house their social rooms, sanitary facilities and offices.
Conclusion: Stay fit for steel production of the future
The steel structures of the building extension, including the supporting structures, roofing and walls, are scheduled to be completed in September 2025. The flooring will be completed in October and November, and the heating, sanitary, electrical and crane systems will be commissioned at the same time. The exterior will be completed just in time for Christmas, which is when the structures will be handed over to the company. Ein bedeutendes „Geschenk“ für greentec steel am Standort Linz, das auch zukünftig die optimale Leistungsfähigkeit der Anlagen und des EAF sicherstellen wird.
Go to greentec steel
The greentec steel project of voestalpine is an ambitious step-by-step plan that makes a valuable contribution to the achievement of the climate goals. As a first step, the voestalpine Group plans to replace two blast furnaces with two electric arc furnaces (EAFs) by the year 2027. The investment volume amounts to roughly 1.5 billion euros.
Carbon emissions can be reduced by up to 30% as early as 2029 by making this switch from the blast furnace to the EAF. This corresponds to a savings of nearly 4 million tons of CO2 per year, amounting to nearly 5% of the carbon emissions in Austria. This makes greentec steel the largest climate protection program in Austria.
The two electric-arc furnaces will enable voestalpine to produce roughly 2.5 million tons of carbon-reduced steel by the year 2027, roughly 1.6 million tons in Linz and 850,000 tons in Donawitz. Learn more about greentec steel here.
