Standing at the heart of Dubai Marina, Ciel Tower rises 373.5 m to claim the title of the world’s tallest hotel, setting a new benchmark for Belt-and-Road landmark hospitality. Developed by The First Group, designed by NORR Architects, and built by China Railway 18th Bureau Group, the tower faces the Burj Khalifa to the east, Dubai Marina to the west, and overlooks the Palm Jumeirah to the north, framing both the city’s skyline and the sweeping Arabian Gulf beyond—redefining the ultra-high-rise resort experience.
Project name: Ciel Tower
Height: 373.5 m
Gross floor area: 102,000 m²
Developer: The First Group
Architect: NORR Group Consultants International Limited
Main contractor: China Railway 18th Bureau Group
Curtain-wall contractor: Shenyang Yuanda Aluminum Industry Engineering Co., Ltd.
Aluminum extrusion supplier: Guangdong Haomei New Materials Co., Ltd.
Occupying a 3,662 m² plot, the hotel delivers 102,000 m² of built area across 82 floors. It houses 1,042 luxury guest suites and 150 upscale residences, complemented by three signature restaurants, a 306 m-high infinity pool, a sky-view bar at 353 m, a full-service spa, and a 12-storey-high atrium sky garden—an ensemble of ultra-premium amenities.
Pushing a super-tall structure to its limits demands core building materials that deliver cutting-edge performance. Ciel Tower must withstand violent high-altitude winds, extreme heat, humidity and salt, while also meeting the structural demands of long-span features and an accelerated construction schedule. Haomei New Materials—ranked among China’s top-ten architectural-aluminium extruders—supplied the premium aluminium profiles that proved critical to solving these challenges.
For the tower’s 373.5 m height and stringent wind-resistance criteria, Haomei delivered 6063-T6 high-strength alloy profiles whose strength markedly exceeds that of standard sections. This ensures the curtain-wall system remains stable under severe wind loads and provides the structural support required for the 15 m-span sky garden. To cope with Dubai’s aggressive coastal climate, the profiles receive a special corrosion-protection treatment and pass the neutral salt-spray test, effectively resisting salt-laden, high-humidity attack and extending the building’s service life.
Energy efficiency and guest comfort also hinge on Haomei’s aluminium profiles. Thermally-broken frames sharply cut heat and sound transmission, holding the indoor–outdoor temperature differential to a fine tolerance. With glazing systems typically accounting for 20–50 % of a high-rise’s HVAC load, the tower’s façade lowers cooling demand while keeping interior noise below 25 dB, giving visitors a hushed, climate-perfect retreat. The alloy’s high formability realizes the architect’s double-curved geometry and ultra-slim sight-lines, and the powder-coated or silver-anodized finishes echo the glass skin with lasting visual crispness—merging sculptural drama with long-term durability.
