High-ceilinged spaces in hollow lobbies often require LED displays to create visual focal points, but traditional screens pose load-bearing challenges due to their heavy weight. Carbon fiber ceiling-mounted mesh screens, through material innovation and structural optimization, achieve a "light as a cicada's wing yet strong as a rock" display solution, offering new possibilities for load-bearing environments.

Material Revolution: The Key to 70% Weight Reduction

The screen frame utilizes T700 carbon fiber composite material, which has a density of only 1.7g/cm³ (approximately one-third that of aluminum alloy) and a tensile strength of 2400MPa (four times that of steel). A 200-square-meter mesh screen weighs only 800kg, a 1.8-ton reduction compared to traditional steel screens. This is equivalent to the weight of 400 bottles of mineral water suspended in a 10-meter ceiling. Carbon fiber's low creep (deformation rate <0.01%) ensures long-term installation without sagging. In a hotel lobby example, the screen maintained a horizontal error of <2mm after five years of use. Structural Innovation: The Load-Bearing Wisdom of Grid Mechanics

Using a regular hexagonal grid topology, a single carbon fiber beam acts as a truss-like support, distributing single-point forces throughout the entire grid. ANSYS finite element analysis shows that a 20-meter span of grid screens can withstand the vibration loads of a Category 12 typhoon, while bearing only 4 kg per square meter. The screen modules are suspended, with silicone shock-absorbing pads absorbing vibration energy and preventing resonance from affecting the building structure. In a museum atrium project, a 60-square-meter grid screen was suspended beneath a glass dome. Architectural design institute calculations showed that the additional load was equivalent to the weight of 0.5 layers of curtains. Project Case: Breaking Through Load-Bearing Limits

Commercial Complex Starry Sky Dome: The 300-square-meter carbon fiber mesh screen utilizes ultra-thin 0.8mm carbon fiber panels combined with transparent light-guiding film, achieving a light transmittance of 35%. It creates a dynamic starry sky effect without obstructing natural light. The overall load is controlled at 5kg/square meter, far below the architectural design requirement of 15kg/square meter.

Airport Departure Hall: The 150-square-meter curved mesh screen is hoisted along the dome's curve. Each module weighs only 1.2kg and is secured with 32 sets of aviation-grade slings. Wind tunnel testing shows that the amplitude is less than 5mm at a wind speed of 25m/s, meeting the airport's high safety standards.

Art Center Multimedia Installation: The 80-square-meter foldable mesh screen utilizes carbon fiber memory alloy connectors. When unfolded, it suspends in a wave-like pattern in the atrium, bearing a load of only 3.8kg/square meter. When retracted, it can be compressed to 150mm, making it easy to transport and install, and suitable for various temporary exhibition settings. Through breakthroughs in both materials science and structural engineering, the carbon fiber hoisted grid screen reduces the load-bearing requirements of LED displays to one-third of traditional solutions. This enables a "visual spectacle with zero burden" installation in load-bearing sensitive areas such as hollow lobbies and glass curtain walls, opening up a new path for the multimedia transformation of architectural spaces.
