The new M5 facility of Manni Sipre, located at the production site in Mozzecane (Verona), was developed to expand the logistics and operational capacity of the division dedicated to the distribution of steel products. The project involved the construction of a new warehouse of approximately 13,800 m², designed for the storage of steel in commercial lengths, addressing the growing need for efficiency in logistics management and supporting the group’s steel supply chain activities.
From the earliest design stages, the project was conceived not only as a functional expansion, but also as a tangible demonstration of how industrial architecture can evolve towards more sustainable models. The goal was to integrate low-impact materials and technologies without compromising structural performance, durability, or construction speed. This approach fostered collaboration between different group companies and technological partners, with a strong focus on innovation and reducing the building’s carbon footprint.
A central role was played by the solutions developed by Manni Sipre and Isopan. The building’s structural framework was constructed using steel components supplied by Steelior, Manni Sipre’s structural division, incorporating low CO₂ steel profiles sourced from international suppliers. These include XCarb by ArcelorMittal, made with over 75% recycled scrap and produced in electric arc furnaces (EAF) powered by 100% renewable energy; Chalibria by AFV Beltrame Group, a carbon-neutral certified steel produced using electric furnaces, recycled scrap and offsetting through certified credits (PAS2060/ISO 14068-1); and ARVZERO by Arvedi Group, an innovative net-zero carbon steel produced via electric furnace with over 90% recycled content and Endless Strip Production (ESP) technology. This material selection enabled the combination of high structural performance with a reduced environmental impact.
For the building envelope, high-performance sandwich panels by Isopan were used, designed to ensure energy efficiency, safety and long-term durability. In particular, approximately 4,500 m² of Isoparete Fire Evo 120 mm panels were installed for the façades, and 9,300 m² of Isofire Roof 80 mm panels for the roofing. These systems provide excellent thermal insulation and fire resistance, contributing to the overall quality of the building and stable internal conditions for stored materials.
The most innovative aspect of the project lies in the insulation material used within the panels. This is the first application of Spanrock Low Carbon (LC Spanrock) stone wool, developed by Rockwool Core Solutions at the request of Isopan. This next-generation mineral insulation is produced using electric melting in arc furnaces, replacing traditional coal-based processes. Thanks to this technology, it is possible to reduce the Global Warming Potential (A1–A3) by up to 45% compared to conventional production methods.
The Environmental Product Declaration (EPD) for LC Spanrock, to be released shortly, will provide even more transparent and verified data to support project certification under leading sustainability frameworks.
In a European context where the building stock must evolve to meet new regulations and climate targets, this project demonstrates a practical path towards decarbonisation. By adopting low-impact materials and construction solutions, the industrial sector can achieve measurable progress in reducing emissions across the entire value chain, particularly in relation to Scope 2 and Scope 3 emissions.
