"Take an open form (for curiosity), a closed form (for competence) and a good portion of invisible forms (for everything that is not prefabricated) and fuse them together... This is how a Denkform®is created."


Christine & Thorsten Seliger
CEOs Denkform
The foundation of our actions

Trust, integrity and fairness
We act honestly, transparently and with the highest ethical standards. Our aim is to maintain trusting relationships and always act responsibly.
Reliability & responsibility
Our customers and partners can rely on us - in every situation. We take responsibility for our actions and stand for quality, adherence to deadlines and sustainable solutions.


Strong partnerships
Long-term, trusting partnerships are the key to sustainable success. We rely on close cooperation, open communication and joint growth.
Sustainability
We offer customized solutions that conserve resources and are efficient. Our focus is on sustainable value creation, environmentally conscious action and future-oriented strategies.

denkform - our guidelines
denkform GmbH has been subject to German law since it was founded in 2001. We are committed to complying with applicable national laws and regulations and to making our daily decisions on this basis and our defined values.
Our business relationships extend beyond German borders, so we take it for granted that we also comply with international legal regulations. This also means that we do not participate in activities that are based on fraud, embezzlement, extortion, theft, embezzlement or any other deliberate damage to the assets of our customers or third parties.
We are convinced of our vision that trust, integrity and fairness are an essential part of our business success. We are working to ensure that this remains firmly anchored in our day-to-day work and to act as a reliable and responsible partner for our customers, employees and partners. Our mission is to make a positive contribution to our customers, employees and partners. We do this by offering our customers tailor-made solutions and contributing to their environmentally conscious and optimized value creation. We network our customers and partners, enabling us to respond quickly and efficiently to the respective current and future challenges of our customers. We are successful because we precisely identify our customers' requirements and offer the optimum solutions to meet them. In doing so, we keep our promises and value fair cooperation. By acting honestly and with integrity, we earn our mutual trust and that of our customers and partners.
We live an open corporate culture. Our talented employees are encouraged and developed. Values such as cooperation, partnership, helpfulness and integration are important to us. Our working atmosphere welcomes questioning things and pointing out inaccuracies. The success of denkform depends on everyone involved behaving honestly, with integrity and fairness. Therefore, denkform's guidelines include truthful and comprehensive communication. Our entrepreneurial success is made possible by heeding and living our guidelines.
As a family business, our guiding values are responsibility, stability, continuity, cohesion and reliability. Non-compliance with our guidelines can lead to considerable damage, not only to our company, but also to our employees and business partners. We do not tolerate breaches of the guidelines. Depending on the severity of the breach, anyone who violates them must expect measures under employment law, civil claims for damages and even criminal sanctions. These guidelines therefore supplement our corporate philosophy and contractual employment agreements.
We position ourselves on the following topics:
Human rights
We respect, protect and promote the applicable regulations for the protection of human and children's rights. We reject any use of child, forced and compulsory labor as well as any form of modern slavery and human trafficking. This also means that we check our suppliers to see whether we receive any indications that children are being employed or that employees are working under inhumane conditions.
Equal opportunities and equal treatment
We offer equal opportunities for all. We do not tolerate discrimination (with regard to salary components, promotions, etc.) on the basis of ethnic or national origin, gender, religion, ideology, age, disability, sexual orientation, skin color, political views, social background or other legally protected characteristics.
Environmental protection
As a commercial enterprise, we are committed to environmental compatibility and sustainability. We rely on environmentally friendly technologies and inform our customers and partners about trade-in processes and recycling. The aim is to maximize the life cycle of the products we sell. We use our resources and energy sparingly.
Communication / Employee development
We value clear and open communication. We respect the performance of our interlocutors, employees and colleagues and uphold their professional and personal reputation. This also means that we respect our employees' right to education, even if we are not legally required to implement a works council. Our employees can join trade unions of their choice. They are treated no differently than any other employee.
Protection of our employees
Although we are not a production company, we ensure that workplace risks for our employees are avoided. We pay particular attention to suitable workplace design and preventive maintenance. Our employees are encouraged to take appropriate breaks to balance their workload, and overtime is only worked by prior arrangement. Protection and security also apply to employee and customer data. We collect, record, process, use and store personal data only in accordance with legal requirements. We pay particular attention to information security, i.e. IT and EDP security.
This is us
A team in which individual strengths combine to form a strong whole. Where work is done with joy and commitment, successes and challenges are mastered together and everyone makes their contribution.
We stand for clear communication, customer-oriented advice and professional solutions - flexible, reliable and passionate.
With us, you gain creative minds, organizational professionals, technology enthusiasts and innovators. Each individual is an indispensable part of our team - together we will find the best solutions for your requirements.
