Product Description

Product Features
Innovative design and structural benefits
Our premium 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 options, allowing the glass panels to fold either inward or outward.

Features a flush fan frame structure to reduce exposed contact points. Both upper and lower parts of the door leaf are made of the same profile without extra 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 wind pressure resistance.

The door structure bears weight at the bottom and guides sliding at the top. The steel pulley parts feature excellent load-bearing and corrosion resistance capabilities.

Custom-made hardware for the folding doors maximizes component concealment while meeting high requirements of functionality and design.

Designed with a dedicated anti-pinch structure to protect hands and ensure a reassuring, user-friendly experience.

Profile surfaces are treated with Akzonobel powder coating, delivering strong weather resistance and a premium frosted texture.
