A: The defining feature of our sliding doors is the minimal central interlock (the vertical bar where two panels meet). It measures just 20mm in width. This creates a virtually uninterrupted panoramic view, maximizing natural light and transparency.
A: Yes. Our system is designed for a "fully concealed" installation. The top, bottom, and side frames can be embedded into the walls, ceiling, and floor, leaving only the ultra-slim central interlock visible. This creates the stunning "floating glass" effect.
A: Absolutely. We specialize in hidden track installations, allowing your indoor flooring to flow seamlessly to the outdoor terrace without any tripping hazards. We use a specialized drainage system (concealed stainless steel tank) to ensure water flows away efficiently, even with a flat track.
A: Our heavy-duty roller system supports massive glass panels. We can manufacture sliding doors up to 9 meters high and 6 meters wide per panel. A single sash can weigh up to 800kg, allowing for truly floor-to-ceiling designs.
