Several decades of experience in the area of aluminium, a consistent quality policy, innovative product development, customer orientation and a reliable supply service from the foundations on which we have built our company into a know-how leader in the field of PREMIUM ALUMINIUM SYSTEMS.

As an owner-managed family business, we think in terms of generations and set ourselves exceptionally high standards. Short term quarterly thinking and shareholder value do not enter our vocabulary.

STEMESEDER stands for quality, innovation, short decision-making paths and sustainability, and not for short term profiteering.
