HAVI has expanded its distribution centre in Azambuja, Portugal, as part of its strategic growth plan. The extension adds more than 8,000 m² to the existing 10,000 m², bringing the total floor area to 18,000 m². This expansion has increased storage capacity by approximately 90% in frozen storage areas and by 30% in ambient temperature areas.

The project combines a steel structure with a self-supporting steel deck roofing system. This solution simplified the roof installation by eliminating the need for secondary purlins. The roof was built using the INCO 155.3 profile, with a thickness of 1.20 mm, employing 15 m long sheets to span 7.50 m in two spans.

Under these conditions, the profile can achieve an ultimate load capacity of approximately 300 kg/m², subject to project-specific verification. This load capacity allows for the integration of a photovoltaic system beneath the roof sheet while supporting permanent loads and snow loads.

This project demonstrates the ideal application of self-supporting steel deck roofing for large industrial buildings. By eliminating secondary purlins, this self-supporting solution reduces installation stages and dead loads. As a result, it offers competitive costs within its range of application while significantly improving construction schedules.
