Thanks to our fully automated technology and contact-free mixer processes, we ensure up to 100% formula accuracy and consistency. The absence of heavy metals such as lead in our raw materials is a clear indicator of our commitment to environmentally friendly manufacturing. Moreover, our production infrastructure is compatible with all climate and geographic conditions worldwide, allowing us to deliver strong, long-lasting, and UV-resistant profiles.

In our production processes, we prioritize environmental sensitivity and energy efficiency, operating within the framework of the EN ISO 50001 Energy Management System and aiming for sustainable manufacturing.
