Exterior Wall Profiles Great Wall Board Price Procurement and Quotation Guide

Industry Background: Thermal Insulation and Energy-Saving Demand Drives Exterior Wall Profile Upgrades

With persistent summer high temperatures, the thermal insulation performance of building exteriors has become a key indicator for engineering procurement. According to the "General Code for Building Energy Efficiency and Renewable Energy Utilization" GB 55015-2021, the heat transfer coefficient of exterior walls in hot summer and cold winter regions must be ≤0.8 W/(m²·K). Traditional single-layer aluminum panels struggle to meet this standard, while exterior wall profiles Great Wall board with thermal break structures effectively block thermal bridges, making them the preferred choice for projects. 佛山市壹元建材科技有限公司, deeply rooted in the local Foshan market, focuses on providing national standard compliant thermal insulation aluminum profiles to help projects achieve energy-saving goals.

Material Characteristics: Structure and Thermal Insulation Principle of Great Wall Board

Exterior wall profiles Great Wall board adopts a composite design of aluminum alloy base material and PA66 nylon thermal break strips, forming a thermal insulation cavity. Experimental data shows that a 25mm wide thermal strip can reduce heat conductivity by over 40%, lowering the overall window heat transfer coefficient K value to 1.8-2.5 W/(m²·K). Surface treatment uses fluorocarbon spraying (three coats one bake) or powder spraying, with weather resistance of over 20 years. The product wall thickness strictly follows GB/T 5237-2017, with main load-bearing parts ≥1.8mm to ensure structural safety.

Engineering Standards and Construction Specifications

Installation of exterior wall profiles Great Wall board must follow the "Technical Code for Metal and Stone Curtain Wall Engineering" JGJ 133-2001. Key points:

• Keel spacing: vertical ≤1200mm, horizontal ≤600mm;
• Connectors use stainless steel bolts, no less than 4 fixing points per square meter;
• Expansion joints between panels reserved 6-8mm, filled with weather-resistant sealant.

During procurement, request the manufacturer to provide profile cross-section drawings, thermal strip test reports, and wind load resistance calculation sheets. 佛山市壹元建材科技有限公司 can provide a full set of technical documents and support on-site technical briefing.

Selection Tips: How to Evaluate Exterior Wall Profiles Great Wall Board Quotations

Exterior wall profiles Great Wall board quotation is affected by the following factors: aluminum ingot price (about 60%), surface treatment process, thermal strip brand (domestic vs. imported price difference 15-20%), and custom length. The price range for conventional engineering sizes (width 100-200mm, thickness 20-30mm) is approximately 150-350 RMB per square meter (including fluorocarbon spraying). The local service capability of Great Wall board profile manufacturers is crucial. 佛山市壹元建材科技有限公司 leverages the advantages of the Foshan aluminum profile industry cluster, direct supply reducing intermediate links, significantly improving cost-effectiveness. It is recommended to request at least three quotations for comparison, focusing on thermal strip material and profile tolerances.
