Custom Flat-Type Refined Steel Profile for Fireproof Glass Curtain Wall, High Precision & Fire Rated, Q345B/Q460 Steel, Customizable Cross-Section
Product Introduction
Designed specifically for fire-resistant glass curtain walls and high-end architectural facades, our flat-type refined steel profiles (also called precision steel profiles) are manufactured using advanced cold-forming and precision welding processes. The unique double-chamber internal structure significantly enhances structural rigidity, while maintaining a sleek, minimalist appearance. The slim cross-section enables larger span installations, perfectly balancing the demand for transparent, open spaces with strict fire safety requirements.
Key Advantages
✅ Slim Profile with Large Span Capacity
Thin cross-section allows larger span structures without compromising strength, delivering unobstructed views and modern minimalist aesthetics.
✅ Fire Rated & High-Strength Steel Construction
Made of Q345B/Q460 high-grade steel, meeting international fire safety standards for commercial and public buildings.
✅ High Precision & Full Customization
Tight dimensional tolerances (±0.3mm) and customizable cross-sections, wall thickness, and lengths to match your architectural drawings.
✅ Prefabricated Modular Installation
Pre-fabricated components for quick on-site assembly, with high finished product fixation strength for reliable performance.
✅ Long-Lasting Corrosion Resistance
Optional hot-dip galvanizing or powder coating treatments for excellent weatherability and long-term outdoor durability.
