Customized Aluminum Profiles for Frameless Curtain Walls - Top China Suppliers & Factory

,

Our products are manufactured with precision tolerances, typically within ±0.1mm, ensuring perfect alignment and seamless glazing, making us a trusted supplier from China.

,

We apply anodizing or PVDF coating to our aluminum profiles, which guarantees corrosion resistance, UV stability, and consistent color quality. For frameless designs, our finishes are tailored to match the glass tint, minimizing visual contrast and enhancing aesthetic appeal.

,

In our factory, glass panels are securely bonded to aluminum supports using high-strength structural silicone, which eliminates the need for visible mechanical fasteners and provides a sleek appearance.

,

We meticulously control silicone joint widths, usually between 6–12mm, to ensure effective weatherproofing while maintaining an almost invisible transition between the glass and the framework.

,

Our aluminum profiles are strategically designed to harmonize with glass reflections, typically utilizing dark or neutral tones to create a subtle shadow line effect, adding elegance to your architectural project.

    Discover the Modern Facade Solution: Our Horizontal Hidden Frame Curtain Wall System
    This precision-engineered aluminum profile system creates seamless glass facades with minimal visible framing. The innovative "cross-shaped" structural design provides exceptional load-bearing capacity while maintaining clean sightlines, maximizing natural light penetration for commercial buildings and high-rise developments. Ideal for office towers, luxury hotels, and institutional buildings seeking contemporary aesthetics with superior weather performance and thermal efficiency.
    This system prioritizes a seamless, all-glass aesthetic. The glass panels are bonded to the aluminum support structure using high-strength structural silicone, minimizing or eliminating visible external aluminum framing. The aluminum substructure remains essential but is largely concealed.
