Great Wall Panel Specifications and Engineering Procurement Guide: From Industry Standards to Energy-Efficient Applications

In high-temperature summer conditions, building thermal insulation and energy efficiency have become core considerations for engineering procurement. Great Wall Panels, as a classic choice for aluminum curtain walls, directly affect thermal insulation performance and structural safety through specification selection. This article provides data-driven selection references for procurement managers from perspectives such as industry standards, material properties, and construction specifications.

Industry Background: Energy-Efficiency Requirements Drive Specification Upgrades

With the implementation of the “General Code for Building Energy Efficiency and Renewable Energy Utilization,” the heat transfer coefficient limits for exterior wall enclosures have been further tightened. Great Wall Panels use thermal break design to effectively reduce thermal bridging effects. The combination of profile cavity structure and thermal strips reduces the overall heat transfer coefficient (U-value) to below 2.0 W/(m²·K), meeting energy efficiency requirements for hot summer and warm winter regions.

Material Properties: Great Wall Panel Specifications and Performance Data

Great Wall Panels are typically made of 6063-T5 aluminum alloy with a fluorocarbon coating for weather resistance of over 20 years. Common specifications are as follows:

• Width series: 100 mm, 150 mm, 200 mm, 250 mm (standard length 6 m, customizable up to 8 m)
• Wall thickness range: 1.5 mm, 2.0 mm, 2.5 mm, 3.0 mm (common engineering choice: 2.0 mm)
• Thermal break type: strip-injection or glue-injection, thermal strip width 15 mm to 24 mm
• Moment of inertia: Ix = 12.5 cm⁴ (example: 200 mm panel width, 2.0 mm wall thickness)

Data shows: larger panel width provides higher bending stiffness but also more significant thermal bridging. Choosing 200 mm width with 25 mm wide thermal strips can achieve optimal thermal performance while maintaining wind pressure resistance (tested per GB/T 15227).

Engineering Standards: Design and Installation Specifications

According to JGJ 133-2001 “Technical Code for Metal and Stone Curtain Walls,” the following points must be noted for Great Wall Panel applications:

1. Connection structure: Use stainless steel clips or corner brackets with spacing ≤ 500 mm to ensure seismic performance.
2. Thermal calculation: Provide a node heat transfer coefficient test report; avoid thermal bridging at broken bridge parts.
3. Installation tolerance: Panel flatness ≤ ±2 mm per 2 m, joint width deviation ≤ ±1 mm.

Selection Suggestions: Matching Engineering Needs

For high-rise buildings (height ≥ 50 m), it is recommended to use panels with wall thickness ≥ 2.5 mm and width 200 mm, paired with deep-cavity thermal strips. For low-rise buildings and decorative moldings, 1.5 mm wall thickness, 150 mm width panels are more cost-effective. Before purchasing, request the manufacturer to provide test reports for wind pressure resistance, air permeability, and thermal performance (three-property tests).
