From March 2026, the company officially becomes part of the Pianca & Partners network, the Milanese hub that brings together companies and professionals in contemporary design.
From the beginning of March 2026, Siderio has joined the Pianca & Partners network, a Milan-based space dedicated to dialogue between companies and design professionals. This step marks a significant milestone in the company’s development and strengthens its presence in Milan, one of the key international centers for design and architecture.
Joining a network of contemporary design
Entering Pianca & Partners represents an important moment in the company’s journey, which over the years has consolidated its role as a technical and project partner for architects, interior designers, and general contractors in the realization of bespoke metal elements and systems.
“Joining Pianca & Partners represents an important milestone for us and, at the same time, a new starting point,” comments Mattia Delbarba, third generation at the helm of the company. “Siderio began as a small artisan business founded by my grandfather Renato and, thanks to the work of my father Gianfranco and the vision developed over the years, it has grown into a recognized partner within the world of design.”
A strategic step toward Fuorisalone 2026
The company’s entry into the Milanese network is part of a broader strategy aimed at strengthening dialogue with the worlds of architecture and interior design. Siderio’s presence within Pianca & Partners will also be part of the path leading to the network’s activities during Fuorisalone 2026.
Within the Milan hub, Siderio will bring its expertise in the transformation of metal for design and furniture, positioning itself as a qualified partner for residential, contract, and professional projects. An entry that marks a new phase in the company’s role within the international design system.
