Product Description

Product Features

These folding sliding doors can seamlessly connect indoor and outdoor spaces. The design without fixed panels ensures an extremely wide opening width, guaranteeing a spacious and comfortable passage. When closed, the large area of folded glass combined with slender profiles creates a transparent indoor and outdoor interactive experience. The system offers versatile opening configurations, allowing the glass panels to fold either inward or outward.
Features a flush fan frame structure to reduce exposed contact points. Both the upper and lower parts of the door leaf are made of the same profile, without any additional overlapping compensating materials.
The brand-new profile concept integrates two different facade visual effects and can achieve completely concealed hardware components.
Reinforcing middle columns are installed between the door panels, ingeniously integrating mechanical components into the door body to enhance overall wind pressure resistance.
Adopts a structural design bearing weight at the bottom and guiding sliding at the top, with vertical coordinated force application. Pulley components are constructed of steel for excellent load-bearing and corrosion resistance.
Custom-engineered hardware maximizes component concealment, meeting strict requirements for both functionality and minimalist design.
The folding door system is designed to prevent hand pinching, providing an extra layer of safety and reassurance during daily operation.
The profile surface is treated with premium powder coating, offering exceptional weather resistance and a sophisticated frosted texture.
This folding and sliding system is an ideal choice for creating transparent, open architectural spaces. When fully open, it maximizes the extension of the indoor living area, and when closed, it provides an expansive, unobstructed view of the outdoors.
