The exterior wall cladding system is a core element of building performance and aesthetics, and strip composite cladding has become the preferred solution for modern architecture due to its innovative design and comprehensive performance. This article systematically analyzes the characteristics of metal, stone, wood, glass, and composite coatings, and explores in depth the unique advantages of strip composite coatings: using high weather resistant composite materials, which combine corrosion resistance, UV resistance, and moisture resistance; The strip-shaped structure not only endows the building with a simple and modern visual hierarchy, but also optimizes thermal and sound insulation performance, reducing energy consumption and noise pollution.
