Application Scenarios

DERCHI's 80 series aluminum folding doors transform spaces by creating seamless transitions between indoor and outdoor areas. These accordion glass doors provide flexible solutions for both commercial and residential projects, maximizing space utilization and natural light.

Advanced Glass Technology

Our double-layer glass system features 5mm+20A+5mm configuration, where the 20mm air gap provides exceptional thermal insulation. Each unit is filled with inert gas to prevent fogging, condensation, and frost formation while significantly enhancing soundproofing performance. The glass panels are separated by PVDF aluminum spacers, ensuring superior corrosion resistance and weather durability for long-lasting performance

Superior Aluminum Materials

We exclusively use 6063-T5 aluminum alloy (silicon-magnesium-aluminum alloy) for all profiles, delivering high strength, excellent mechanical properties, superior toughness, and outstanding corrosion resistance. The 2.0mm wall thickness ensures structural stability and durability. All surfaces undergo powder coating (standard and metallic powders) with sandblasting pretreatment to remove contaminants and micro-burrs, significantly improving surface adhesion and coating bonding strength.

Advanced Assembly System

Frame and glass panels connect at 45° angles for aesthetic appeal and functionality. Frames utilize expansion corner codes for efficient assembly and flat corner joints. Glass panels feature integrated injection-molded corner codes for robust, durable construction. Bottom rails employ 90° screw connections to ensure secure and efficient assembly throughout the system.

Professional-Grade Hardware Solutions

Our systems incorporate stainless steel bottom support wheels and high-capacity hinges designed to handle large door panels reliably. The hinges feature built-in adjustment mechanisms that effectively prevent door sagging over time. Zinc alloy drainage covers are installed at drainage points to prevent water backflow while eliminating wind whistling and other noise issues.

Intelligent Structural Design

The high-track design uses unified profiles for frames and tracks with 45° connections, enhancing both aesthetics and water resistance. Low-profile tracks support embedded installation for barrier-free access. Water-resistant low tracks accommodate embedded installation with indoor-outdoor height differences ensuring waterproofing and smooth passage. Double sealing strips provide water protection and finger-safety features. The stainless steel bottom track delivers excellent load capacity and smooth operation.

Space-Efficient Specifications

The system occupies only 80mm of wall thickness while ensuring installation stability. Frame visible width measures 65mm, matching the 65mm surface dimension of top and high tracks for visual unity. The special low-profile track measures just 20.1mm, embodying barrier-free design principles. Water-resistant tracks at 55mm prevent rain infiltration while improving overall sealing. Glass panel face width of 55mm creates a slim profile that maximizes light transmission and transparency. The 70mm panel thickness accommodates high-performance multi-layer insulated glass for enhanced energy efficiency.
