A new approach to construction

STEEL AS A SUSTAINABLE BUILDING MATERIAL

In addition to its strength, steel is a key component in the construction industry's current transformation, allowing for more efficient and sustainable use of resources. Its exceptional durability, complete recyclability, and high load-bearing capacity make it a building material that meets not only technical but also ecological requirements. In the face of mounting pressure on resources and escalating climate protection requirements, steel provides a viable solution for the efficient, flexible and sustainable design of construction projects.

Steel proves its strengths particularly in the context of the circular economy: It can be recycled infinitely without any loss of quality. This is a significant advantage over many other building materials. Salzgitter AG further enhances this material advantage with technological innovation: The use of green electricity in electric arc furnaces is already well-established, and the planned gradual introduction of hydrogen-based direct reduction will see the consistent promotion of low-CO2 steel production.

Circularity with steel

A BUILDING MATERIAL IN THE CIRCULAR ECONOMY

Steel is the ideal material for circular construction. Its high material quality is retained for decades, enabling flexible repurposing and extended usage phases. Structures and components can be dismantled by type and reused directly, either in the same project or elsewhere.

Individual components and materials can also be efficiently reused before the material is finally recycled completely. Steel is a highly versatile and sustainable material, with its 100 % recyclability and consistent quality ensuring it is an essential component in the construction industry's efforts to conserve resources and reduce emissions.

THE GREEN STEEL HOME AS A TREND SETTING CONSTRUCTION CONCEPT

Our Green Steel Home reference project is a prime example of how circular construction works in practice, showcasing flexible usage concepts, easy dismantling, and the use of our low-emission beams made from SALCOS® Structural Steel.

The self-supporting steel structure forms the core of the innovative living concept, allowing maximum design freedom in terms of use and reuse of the building elements.

OUR GREEN STEEL PRODUCTS FOR A SUCCESSFUL TRANSFORMATION OF CONSTRUCTION

The recent changes in the construction industry have highlighted the need for building materials that offer both high performance and climate-friendly credentials. Green steel products are the answer: they combine the proven static and structural properties of steel with significantly reduced CO2 emissions during production. 

Salzgitter AG is currently in the process of transforming to low-carbon steel production. While direct reduction with hydrogen is currently being prepared and will be gradually implemented in the coming years, the electric furnace route is already being used successfully today—powered by green electricity and recycled scrap. This means that significant emission reductions can already be achieved today, while at the same time the infrastructure for climate-friendly direct reduction is being established.

CERTIFICATES

In order to ensure that construction is environmentally sustainable, it is essential to have reliable information about the materials being used. In the face of mounting pressure for climate protection and resource conservation, sustainable construction has emerged as a main challenge for the construction industry, transcending the status of a mere ideal.

The selection and evaluation of building materials plays a central role in this, as it significantly influences the ecological impact of a building throughout its entire life cycle.

Certification and verification of building materials are essential to make these impacts transparent and comparable. They provide reliable data on environmental impact, enable the calculation of a building's total emissions, and engender trust among builders, planners and investors.
