A positive start to the year in a difficult industry situation: Salzgitter AG reports growth in important business segments, while the European steel industry continues to suffer from overcapacity, high energy costs, and import pressure. The integrated steel group from Lower Saxony, which produces both structural steel and reinforcing steel according to DIN 488, benefits from its broad positioning across multiple business fields.
While competitors like ThyssenKrupp and ArcelorMittal struggle with restructuring, the strategic diversification of Salzgitter AG proves to be a stabilizing factor. In addition to classical steel production using the blast furnace process, the portfolio includes areas such as heavy plate, precision tubes, and technologically specialized products. This alignment enables the group to cushion demand fluctuations in the construction sector – a major customer for long products and reinforcing steel – through other segments. The recent acquisition of control over the HKM steel plant in Duisburg also expands capacity in flat steel production.
For the building materials industry, the availability of code-compliant reinforcing steel according to DIN 488-1 and structural steel according to DIN EN 10025 is of central importance. Salzgitter serves this market with products of strength classes BSt 500 S (characteristic yield strength 500 N/mm²) as well as structural steels up to S355. The group's stable delivery capability directly impacts the calculations of reinforced concrete projects, as price stability and availability are essential factors in project planning.
In parallel with operational performance, Salzgitter AG is advancing the transformation toward climate-neutral steel production. The SALCOS project (Salzgitter Low CO₂ Steelmaking) envisages the gradual replacement of blast furnaces with direct reduction plants, in which iron ore is reduced with hydrogen instead of coke – similar to the approaches of SSAB and voestalpine. The production of green steel using hydrogen could reduce CO₂ emissions by up to 95%, which is particularly relevant for EPD-based building certifications according to DGNB. However, the economic framework conditions of this transformation are in focus: The uncertainty regarding US tariff refunds burdens export calculations and thus the refinancing of investments in climate-neutral production processes.
For planners and civil engineers, the positive start to the year for Salzgitter AG initially means a secure supply of code-compliant steel products. In the long term, it will be crucial at what prices and in what quantities green steel will be available – and whether it will be economically viable through lower CO₂ balances in the overall project evaluation.
