Great Wall Board Ceiling Wholesale Procurement and Quotes: Engineering Selection and Technical Guide

During the hot summer season, the demand for thermal insulation and energy efficiency in building ceiling systems increases significantly. Great Wall board ceilings, as an aluminum alloy ceiling solution combining decoration and functionality, are widely used in shopping malls, office buildings, hospitals, and other public buildings. This article provides professional references for engineering procurement on wholesale selection and quotation of Great Wall board ceilings, from the perspective of industry standards, material properties, and construction specifications.

Industry Background: Application Trends of Great Wall Board Ceilings in Thermal Insulation and Energy Saving

According to the General Code for Building Energy Efficiency and Renewable Energy Utilization (GB 55015-2021), the heat transfer coefficient of public building envelopes must meet strict limits. Aluminum alloy Great Wall board ceilings, due to their metal reflective properties, can effectively reduce solar radiation heat absorption. Combined with insulation rock wool or glass wool layers, they can significantly reduce air conditioning energy consumption. Foshan Yiyuan Building Materials Technology Co., Ltd. specializes in direct supply of engineering aluminum materials, leveraging the local industrial chain advantages in Foshan to provide Great Wall board ceiling products that meet national energy efficiency standards.

Material Properties: Performance Parameters of Aluminum Alloy Great Wall Boards

The base material of Great Wall boards is 3003 series aluminum alloy, with a thickness typically of 0.6-1.2 mm. The surface is treated with fluorocarbon spraying or polyester powder coating, providing weather resistance exceeding 20 years. The thermal conductivity of aluminum alloy is approximately 230 W/(m·K), but through an air gap or filling with insulation material, the overall heat transfer coefficient can be reduced to below 0.5. Common board widths are 100-300 mm, and lengths can be customized up to 6 meters. A variety of colors and wood grain textures are available to meet diverse design needs. For specific performance parameters, refer to the standard GB/T 23444-2009 Metal and metal composite panels.

Engineering Standards: Key Points of Design and Construction Specifications

• Design specifications: Great Wall board ceiling systems shall comply with Code for acceptance of quality of building decoration engineering (GB 50210) and Code for acceptance of energy efficient building construction (GB 50411). The spacing of keels is typically 600-900 mm, and wind loads and maintenance loads should be considered.
• Insulation structure: It is recommended to lay 50 mm thick rock wool (density ≥100 kg/m³) behind the panels and use a breathable membrane to prevent condensation.
• Installation requirements: Reserve expansion joints (≥5 mm) between panels, use dedicated clips for connection, and ensure flatness deviation ≤2 mm/2 m.

Selection Suggestions: How to Choose a Great Wall Board Ceiling Factory

In wholesale procurement of Great Wall board ceilings, focus on the manufacturer's qualifications, product test reports (e.g., salt spray test ≥1000 h, color difference ΔE ≤1.5), and supply capability. Foshan Yiyuan Building Materials Technology Co., Ltd., as a professional Great Wall board manufacturer, offers free samples, detailed design, and transportation services. We can customize sizes according to engineering drawings to reduce on-site waste. For summer heat insulation projects, we recommend products with high-reflectance coatings (solar reflectance index SRI ≥80) to further enhance energy efficiency.
