High Strength Ri Section Precision Steel Profile for Building Curtain Wall, Fireproof Anti-typhoon Shock Resistant Custom Steel Profile
Product Introduction
Ri section precision steel profile is a high performance cold formed steel material developed specially for building curtain walls and exterior facades. Its cross section looks like Chinese character Ri, combining solid structural rigidity, transparent visual effect and multi disaster resistance performance.
Boasting yield strength up to 460MPa and above, the profile realizes large span application with slim body, fully complying with fire safety, wind pressure and seismic design standards.
Core Advantages
• Slim profile design supports large span use, beautiful transparent effect without sacrificing structural safety
• Modular prefabricated structure enables fast installation and stable overall performance
• Multiple sizes available, customized processing to meet diverse architectural design demands
It delivers reliable fire protection capability while retaining elegant building appearance, perfectly unifies fire safety, practical functions and architectural aesthetics.
• High strength raw material effectively lowers wind resistance under strong wind pressure
• CNC cold bending processing keeps forming tolerance within ±0.3mm, uniform stress distribution without local stress concentration
• Scale shaped interlock structure and multi-direction drainage channels efficiently disperse wind impact force
• Built-in energy dissipation connectors buffer vibration and enhance overall structural stability
• High material ductility with fracture elongation over 18%, resistant to brittle fracture under deformation
• Yield ratio below 0.75 balances structural strength and shock absorption capacity
• Flexible 3D adjustable joints release seismic force and reduce inertial force transmission
• Double shock resistance structure layer absorbs seismic energy step by step
Stable structure keeps intact even under severe earthquake impact
