How to select mesh panel patterns for light diffusion control?

Aluminum mesh panels serve as architectural screens that modulate natural light, reduce glare, and distribute daylight evenly. To optimize light diffusion, begin by evaluating perforation geometry: round holes offer soft-edged light patterns, while elongated slots create linear light striations. Slot widths of 2–4 mm with 15–25 % open area yield a balance between daylight penetration and shading. Hexagonal or staggered patterns scatter light more diffusely, minimizing hotspots and contrast. Pattern orientation also matters: aligning elongated perforations horizontally can soften direct sun angles, while vertical slots emphasize vertical light shafts. When maximizing uniformity, choose high-density micro-perforations (0.8–1 mm diameter) with open-area ratios below 10 % in combination with a backlit diffuser or translucent membrane. For dynamic visual interest, consider gradient open-area panels—denser perforations at the top transitioning to wider spacing below—to adapt light levels across a façade. Incorporate photometric studies (e.g., daylight factor analysis) to simulate how mesh patterns influence interior illuminance. By selecting the right pattern geometry, open-area ratio, and orientation, aluminum mesh systems can transform harsh sunlight into comfortable, evenly distributed daylight.
