In outdoor buildings, the spacing of aluminum batten can be appropriately increased, usually between 50-100 cm. This setting can reduce the amount of materials used and reduce costs while meeting functional requirements such as ventilation and lighting.

Aluminum batten, known as "aluminum batten" in English, is a long and thin strip of material made of aluminum alloy. The cross-section of aluminum batten is usually rectangular or other regular shapes, and the length and thickness can be customized according to specific needs. Aluminum batten usually has high corrosion resistance, excellent mechanical properties, and light weight and high strength.
