Sustainability as the key to long-term quality

DENA Stahlbau is committed to sustainability and consistently follows environmentally friendly practices. As a dedicated user of the German Sustainability Code and with an ISO 14001:2015 certified environmental management system, DENA has firmly embedded ecological responsibility in its corporate philosophy. Part of our commitment to renewable energy is demonstrated by the use of a photovoltaic system that further reduces our ecological footprint.

One key aspect of our sustainability efforts is the use of green steel from Stahlwerk Thüringen, which is obtained exclusively from recycled steel scrap. This practice lowers CO2 emissions by more than 50% compared to conventional steel production methods and effectively supports the circular economy. By working with pioneers like Stahlwerk Thüringen, DENA is making an active contribution to climate protection while ensuring the high quality and sustainability of its products.

In addition, DENA Stahlbau is also committed to upholding labor and human rights and acts strictly according to ethical principles. Our corporate policy is based on international standards and we place a high value on fair working conditions and the protection of human rights along the entire supply chain. Sustainable procurement is a key concern here, in which we work responsibly with our suppliers to ensure that our material and services are purchased under fair and ethical conditions.

Our commitment to a sustainable future is firmly rooted in our identity and reflects our desire to act responsibly and promote positive environmental impact. In doing so, DENA strictly adheres to the Code of Conduct to ensure the highest standards in all areas of business.
