HYQJ120/155QC series panoramic heat-insulated sliding door is a narrow-edge American style panoramic product built with systematic thinking.

This series can be opened in the forms of two sliding sashes with one fixed sash, four sashes (two fixed and two sliding), or a central fixed sash flanked by two sliding sashes.

The lower track adopts a combined sinking drainage, which is conducive to the lower pulley not being easily immersed in water, using water pressure to drain water, smooth drainage, beautiful appearance, and increasing the service life of the lower pulley.

The lower track adopts a double-track design, and the glass sash adopts an ultra-load-bearing double-row wheel to make the door open and close more smoothly.

The door sash adopts a multi-strip sealing design, and the upper and lower overlapping parts of the indoor and outdoor sashes are equipped with special sealing accessories to block strong winds, insect-proof, dust-proof and water-proof.

The upper and lower hook cover sealing parts are added at both ends of the sash hook cover to increase its sealing performance and aesthetics.

The upper track is equipped with an anti-sway guide groove, and the door sash can use a rear-mounted adjustable anti-sway wheel to reduce the swing and shaking of the door sash during the sliding process.

Featuring an integrated design of glass and frame, this system elevates both elegance and function. It offers optimized sightlines, robust safety, and a structurally sound, aesthetically superior solution.
