Aluminum Great Wall Panel Specifications: A Complete Engineering Selection Guide

With the increasing demand for both decorative and functional performance in modern architecture, Aluminum Great Wall Panels (型材长城板) have been widely used in commercial facades, subway stations, airports, and other projects due to their unique three-dimensional texture and excellent weather resistance. Especially in high-temperature summer environments, the heat-insulating reflective coating on Great Wall panels can help reduce building energy consumption, aligning with green energy-saving trends. This article systematically analyzes Aluminum Great Wall Panel specifications from five dimensions: industry background, material characteristics, engineering standards, selection recommendations, and procurement guidance, providing a reference for engineering procurement.

1. Industry Background and Application Trends

Aluminum Great Wall Panels are a type of aluminum decorative panel with a continuous concave-convex cross-section resembling a city wall, hence the name "Great Wall Panel." The 2024 standard GB/T 23443-2024 for "Aluminum Single Panels for Building Decoration" specifies the mechanical properties and coating requirements for Great Wall panels. Currently, the engineering market demands Aluminum Great Wall Panel specifications with widths of 100-200mm, heights of 20-30mm, and lengths customizable up to 6 meters. Driven by summer heat, products with heat-insulating reflective coatings (such as PVDF and polyester) are preferred.

2. Material Properties and Thermal Insulation

The base material of Aluminum Great Wall Panels is 3003 or 5052 aluminum alloy, with a thickness typically of 0.8-1.5mm. The unique structure creates an air convection layer, and when combined with a low-emissivity coating, it reduces the heat transfer coefficient. Laboratory data (source: National Aluminum Profile Quality Inspection Center) shows that Great Wall panels with PVDF coatings can reduce surface temperature by 8-12°C compared to ordinary aluminum panels, effectively lowering indoor air conditioning load. Typical Aluminum Great Wall Panel specification cross-section parameters are shown in the table below:

3. Engineering Standards and Installation Specifications

According to GB 50210-2021 "Acceptance Standard for Quality of Building Decoration Engineering," Great Wall panel installation must ensure purlin spacing ≤600mm, panel joints of 3-5mm, and the use of hot-dip galvanized steel purlins. For Aluminum Great Wall Panel specification tolerances, the national standard requires width deviation ±0.5mm, height deviation ±0.3mm, and flatness ≤1.5mm/m. For thermal insulation projects, it is recommended to lay a 5mm thick reflective film behind the panels to further enhance energy efficiency.

4. Selection Recommendations

1. Choose coating based on environment: For high-corrosion coastal areas, PVDF coating is preferred; for inland areas, polyester coating is acceptable. 2. Choose thickness based on span: When purlin spacing ≤600mm, 1.0mm thickness is recommended; for >600mm, 1.5mm is required. 3. Insulation requirements: In high-temperature summer regions, choose Aluminum Great Wall Panel specifications with heat-insulating reflective coating, such as CCB-20030-F.
