As a flagship retail development on the Red Sea coast, the Mall of Arabia required a striking tensile roofing system to serve both as a visual icon and a climate-adaptive solution. Tamimi Steel & Membrane engineered and delivered one of the largest membrane roof systems in the region, ensuring durability, efficiency, and architectural impact.
The roof spans 22,000 m² and combines flying masts, arch and ring trusses, and perimeter steel framing to achieve long-span coverage and structural stability. The PTFE membrane panels form a lightweight yet powerful enclosure, optimized for light diffusion and thermal comfort.
The steelwork used carbon steel pipes and cold-rolled beams (ASTM A53 G-A / SASO SSA 1011), assembled with stiffeners and gusseted connections. The system integrates flying masts and compression rings to distribute membrane tension and wind loads effectively across the span
- The tensile roof is integrated with the mall’s main façade, acting as both a cover and a light-filtering element. The PTFE fabric allows controlled natural light, reducing HVAC load while preserving a bright, open atmosphere for shoppers.
Structure and Cultural Form
The tensile structure’s elegant curves and elevated masts provide a dynamic form that redefines the retail experience. It reflects both engineering rigor and architectural flair—perfectly aligned with the mall’s positioning as a premium destination.
