It features a flush fan frame structure to reduce exposed contact points. The special feature lies in that 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 the wind pressure resistance of the door.

The entire door structure design adopts the principle of bearing weight at the bottom and guiding sliding at the top, with vertical coordinated force application. The pulley parts are made of steel, featuring excellent load-bearing and corrosion resistance capabilities.

Hardware is an important component of the new platform. Custom-made hardware for Kassel folding doors maximizes the concealment of components and meets the extremely high requirements of functionality and design.

The KASAIER folding door is designed to prevent hand pinching, making it more reassuring to use.

The surface of the profile is treated with Akzonobel powder coating, which has strong weather resistance and a frosted texture that fully showcases its versatility and high-end quality.
