SLEEK has always focused on the research and development and production of minimalist doors and windows. While ensuring the structural safety and functionality of our door and window systems, we strive to use simple, extremely narrow geometric lines to showcase the visual appeal and artistic expression of the doors and windows in conjunction with the architecture. SLEEK follows the architectural design philosophy of "Less is More" proposed by the modernist architect Mies van der Rohe. "Less is more" is not a trend, but a core principle.

SLEEK champions simplicity. We use technological methods to simplify doors and windows, refining each design element to a cleaner, purer expression. SLEEK minimalist sliding doors bring more light into the building's interior, creating a transparent space and better showcasing the connection between the interior and exterior.

SLEEK features large expanses of transparent glass and a simple structural system. From the inside out, it seamlessly integrates the interior and exterior views, and from the outside out, it also allows the two to flow together into a single space.
