Andera Expansion, Andera Partners’ team dedicated to small and mid-cap companies, becomes the majority shareholder of Sotralu, a European specialist in premium aluminium joinery solutions, alongside the management team.
Through this transaction, Andera Expansion and the management team intend to consolidate Sotralu’s position as one of Europe’s leading suppliers of accessories for aluminium joinery and accelerate its growth.
Founded in 1978, Sotralu is a leading European player in the design and manufacture of premium solutions for aluminium joinery. The Group offers a comprehensive range covering all major window and door opening systems, including sliding, tilt-and-turn and casement systems, as well as locking systems, handles, hinges, rollers, corner profiles and other accessories.
Sotralu relies on an integrated industrial platform comprising four complementary sites located in France, Portugal and Italy. The Group generated approximately €45 million in revenue in 2025 and employs more than 200 people. International sales account for 75% of its revenue, with products sold in 46 countries to a loyal and diversified customer base of more than 300 clients. This broad product offering, combined with a recognised in-house engineering and design office, enables Sotralu to meet the most demanding specifications of aluminium system houses and window manufacturers across Europe and beyond.
This European platform has been built through acquisitions, including Erreti in 2013, GNS in 2018 and FR Accessories (Ragni) in 2023. Each acquisition has expanded the Group’s product offering and geographic reach. Following this change in ownership, Sotralu intends to use this new phase to accelerate its development through the launch of new products supported by its engineering and design office, the development of cross-selling opportunities between the Group’s entities and continued international expansion. Further M&A opportunities will remain a key driver of value creation for the Group.
A senior financing package led by BNP Paribas, LCL and Caisse d’Epargne complements the financing of the transaction and provides additional facilities to support industrial investments and future M&A opportunities.
Sotralu’s management team: “We are delighted to welcome Andera Partners as we enter a new phase of profitable growth for the Group. We would like to thank Bridgepoint Capital for its support in completing the acquisitions carried out during its ownership period.”
David Robin, Partner at Andera Partners: “We are convinced that Sotralu has strong fundamentals to return to sustainable growth. The Group has recognised industrial expertise, a highly complementary European platform and a high-quality product offering. We are fully committed to supporting the management team in this new phase of development, with the ambition of providing it with the resources required to accelerate growth.”
