Supermarket chain ALDI has opened its first store in Montcada i Reixac, located at 3 Plaça d’Espanya. The new supermarket has a sales area of more than 1,000 m², 71 parking spaces and a team of 17 employees, strengthening the company’s presence in Catalonia.
The project features a self-supporting roof deck made with the INCO 155.3 Deck profile, 1.00 mm thick. S280GD steel was used, with Z225 protection and a 25-micron pre-painted finish in Pirineo white.
One of the main challenges for the roof was adapting it to the structure. The main area comprises large bays, with spans of up to 8.10 m, which the INCO 155.3 Deck profile supports directly. The project also specifies a deflection limit of L/300, which is particularly demanding for spans of this size.
The profiled sheet therefore acts as the load-bearing element between the main supports. This removes the need for a conventional purlin system in this area of the roof. Its 155 mm depth provides the stiffness required to span these distances, while keeping the solution lightweight and simplifying the structural layout.
The remaining roof layers—thermal insulation and an external waterproofing membrane—are installed above the metal profile. The INCO 155.3 profile serves both as a structural element and as the base for the roof build-up.
The solution used in Montcada i Reixac shows how a deep profile can be adapted directly to the main structure, reducing secondary components and simplifying installation. This approach is particularly suitable for industrial, commercial and logistics buildings with large spans between supports.
