80 Folding Door

Guangdong DERCHI Doors & Windows Co., Ltd. specializes in high-end aluminum system doors and windows, with a core focus on safety, innovation, and smart home integration. The 80 Series Folding Door exemplifies their commitment to merging functionality with aesthetic design, tailored for modern residential and commercial spaces. Below is a detailed overview:

Core Features & Technologies

Space Optimization:

The folding door utilizes a multi-panel folding mechanism that slides smoothly along an upper track system. When fully opened, it achieves near-total space openness (up to 100% opening rate), seamlessly merging indoor and outdoor areas (e.g., living rooms with balconies or courtyards). This design maximizes natural light and visual continuity.

Key Features of 80 folding Door

The 80 Bifold Door, engineered to blend design aesthetics with practicality, simply proves that all its features complement each other in the achievement of smooth operation, maintenance of structural integrity, and added aesthetic appeal to the space it serves.

Thermal Break Design

Heat loss is decreased to the lowest minimum; hence, energy costs are reduced.
Top-Hung Bottom-Sliding System

Properly guided from the top with the weight distribution done across the track to give maximum stability.
Concealed Hinge Design

Hidden hinges create clean sight lines and at the same time provide strength to the overall structure.
Reinforced Intermediate Posts

Structural reinforcement between panels not only increases its resistance to wind pressure but also balances the force.
Balanced Force Distribution

Central force points prevent any form of uneven stress which tends to cause door sagging and warping.
Self-Adjusting Hinges

With adjustment features incorporated into the hinge, it helps to compensate for the settling condition and reduces maintenance to be done periodically.
Balanced Bearing Technology

Precision bearings reduce friction to a minimal level to make it work smoothly and without much effort.
ENHANCED WATERPROOFING

Optional water-blocking low threshold track will prove very helpful when water tries to infiltrate, especially during periods of heavy rain.
MINIMALIST MODERN DESIGN

Clear lines, with hidden structural elements maximizing the glass area with the least obstruction.
