Aluminum + Stainless Steel Dual Material: Aluminum alloy framework for lightweight high-strength performance, stainless steel reinforcement at critical structural points — dual-material combination balancing outdoor weather resistance with structural security, more comprehensive and reliable than single-material solutions
Outdoor-Specific Anti-Corrosion Treatment: All metal components undergo multiple anti-corrosion processes (anodizing/electrophoresis/powder coating) — UV-resistant, acid rain-proof, salt spray-proof, no rusting or fading from long-term outdoor exposure
1.5-Hour Fire-Rated Structure: Door body interior featuring professional fire-resistant thermal insulation materials — even as an outdoor courtyard gate, maintaining complete fire barrier capability, providing perimeter fire protection for courtyard buildings
Anti-Theft Reinforced Design: Stainless steel reinforcement at critical stress points + professional outdoor security locks + thickened door structure — courtyard gate security as the first line of defense cannot be compromised
Finished Outdoor Coating: Surface treatment specifically optimized for outdoor environments — weather resistance far exceeding indoor door standards, colour maintaining 5+ years without noticeable change through sun and rain exposure
Manual Opening Mechanism: Outdoor-environment-specific manual opening system — no electrical power required, unaffected by power outages or wiring faults, reliable all-weather operation
