Technical Definition
Aluminum alloy curtain wall is a non-load-bearing exterior building enclosure system constructed from precision-formed aluminum alloy panels and paired glass units, designed to deliver weather resistance, structural stability, and architectural design flexibility. Developed based on modular dry-hanging structural principles, it reduces building load and lowers long-term maintenance costs. As a core solution in the building decoration industry, it supports the upgrading of super high-rise and landmark building facades. Main product series include: 1. Fluorocarbon aluminum veneer series: A high weatherability standard series suitable for coastal, high-temperature, and sandstorm-prone regions, with 25+ years of service life and resistance to UV and salt spray erosion.
2. Unitized glass curtain wall series: A high-efficiency prefabricated series suitable for super high-rise projects, with factory pre-assembly and fast on-site installation.
3. Framed glass curtain wall series: A cost-effective standard series suitable for mid-rise commercial buildings, with flexible panel layout and easy maintenance. The product design follows core principles of high reliability, long service life, low maintenance, and design adaptability, with full consideration of harsh outdoor working conditions and full lifecycle reliability design standards.
Technical Principle
The core working principle of the system is based on modular dry-hanging structural design. Aluminum alloy panels and glass units are mounted to a concealed aluminum alloy keel framework via precision mechanical fasteners, eliminating the need for wet mortar installation. The full operation logic follows a clear chain: 1. Structural load transfer: Panel dead load, wind pressure, and seismic forces are transferred directly to the building main structure through the keel system, avoiding concentrated load on the building facade.
2. Weather sealing: Multi-layer EPDM gaskets and sealant create a continuous air and water barrier to prevent rain penetration and air leakage.
3. Thermal expansion accommodation: Designed sliding connections between panels and keels accommodate material expansion and contraction across extreme temperature ranges, preventing structural deformation. Core innovative design modules include the multi-layer fluorocarbon coating layer, which delivers 30-year color retention and resistance to acid rain and salt spray, and the modular keel system, which enables quick alignment and single-panel replacement without full facade disassembly. Compared with traditional stone curtain walls, the system reduces facade weight by 60-70% to cut structural foundation costs, and eliminates the 3-5 year repainting cycle required for traditional paint and tile facades.

Technical Advantages and Differentiation
Compared with conventional aluminum curtain wall products in the global market, our solutions have formed verified core competitive advantages through independent R&D and technical innovation, validated by long-term application across global client projects. 1. Long-term weatherability in harsh outdoor environments: Supported by automated fluorocarbon spray lines with 70% PVDF resin content, tested per ASTM B117 salt spray standard. The coating retains 90% of original color after 25 years of outdoor exposure, with no chalking or peeling in accelerated aging tests. This eliminates frequent facade repainting cycles, reducing long-term maintenance costs by 60% compared to traditional systems.
2. Flexible custom fabrication for complex architectural designs: Supported by 20 automated CNC processing lines and an in-house design team for facade deepening. The system can fabricate double-curved, perforated, and large-format panels up to 3m x 6m, with dimensional tolerance controlled within ±0.5mm. This enables realization of complex curved facades that cannot be achieved with prefabricated stone or tile products, while reducing on-site modification work.
International Standards and Compliance
All R&D, design, production, and testing processes strictly follow the latest international standards and industry specifications, with a complete compliance system to meet procurement and regulatory requirements across global markets. Core followed standards include ASTM E119 fire resistance, ASTM E331 water penetration, EN 13830 curtain wall performance, and BS EN 12179 wind resistance standards. The products hold ISO 9001 quality management, ISO 14001 environmental management, and EU CE certifications, with full third-party test reports, material certificates, and compliance declarations available for all export markets.
Typical Application Scenarios
Aluminum alloy curtain wall systems are widely applied across global industries, providing mature and stable technical solutions for diverse project requirements. 1.
