Product Features: Unique shaped blades in a梭形 (streamlined) design, with a double-arc surface, offering an elegant and technologically advanced look to enhance the modernity of architectural appearance. Large cross-section and hollow structure for high strength, suitable for large-span installations, and also protective for glass curtain walls. The blade angle is adjustable from 0° to 105°, controlled by either electric or manual means, allowing for the adjustment of blade angles according to solar angles to achieve a balance between shading and daylighting. Driven by a concealed motor or an external motor linkage, the structure is scientifically designed, easy to install and assemble, and operates stably. Diverse installation options support both horizontal and vertical installations, suitable for indoor and outdoor shading on flat, vertical, and sloping buildings. Blade color can be customized according to the designer's or client's requirements, complementing the architectural decor style. High-performance materials typically use aluminum alloy blades, coated with fluorocarbon for corrosion resistance, aging resistance, wind pressure resistance, waterproofing, wear resistance, and sun resistance, with a long service life. A variety of blade sizes are available (e.g., 85mm, 180mm, 210mm, 250mm, 300mm, 450mm, etc.), suitable for actual needs.
