4. Product Description

The 21m Heavy-Duty Clear-Span Marquee is an ultra-robust, large-scale structure engineered for the most demanding event environments, including high-rise rooftops, commercial plazas, and grand outdoor weddings. With a massive 21-meter column-free width and a soaring 7.36m ridge height, it provides a colossal interior volume. Crucially, its reinforced frame is specifically designed to withstand the high-wind conditions often encountered in elevated rooftop installations.

Key Features:

• Ultra-Heavy-Duty Frame for High-Wind Areas: Constructed with massive 112*203*4mm extruded aluminum alloy (GB6005-T6). This extra-thick 4mm profile provides exceptional structural rigidity, making it highly secure for rooftop venues and coastal areas prone to strong winds.

• Infinite Modular Configuration: The 21m span is fixed, but the length can be scaled infinitely in 5m bays (e.g., 21x30m, 21x40m, 21x50m) to perfectly adapt to the specific dimensions of your rooftop or ground-level venue.

• Industrial-Grade Weather Protection: Features double PVC-coated fabric (750gsm roof, 650gsm sidewalls) that is 100% waterproof, UV-resistant, and flame retardant (DIN 4102 B1 standard), ensuring absolute safety and comfort for high-profile guests.

5. Applications

Thanks to its extreme structural stability and grand scale, this 21m marquee is the premier choice for luxury hotel rooftop venues, commercial plaza activations, grand wedding banquets, and high-end corporate galas. It transforms exposed, wind-swept outdoor spaces into secure, majestic, and fully climate-controlled event hubs.
