Aluminum profiles for curtain walls are the primary structural material used in building curtain wall systems. Made from high-strength aluminum alloy through extrusion molding, they possess characteristics such as lightweight, corrosion resistance, ease of processing, and recyclability.
In practical applications, aluminum profiles for curtain walls require precise design based on building height, wind pressure, seismic resistance levels, and thermal performance requirements. Profile cross-sectional forms are diverse, commonly including exposed frame, concealed frame, semi-concealed frame, and unitized systems. Different systems impose varying requirements on the strength, stiffness, and sealing performance of the profiles. For example, concealed frame curtain walls rely on structural adhesive to fix the glass, requiring profiles with precise groove dimensions and surface treatment quality to ensure reliable bonding; while unitized curtain walls emphasize the modular assembly precision and airtight and watertight performance of the profiles.
