Thin Frame Sliding Door

❶High-Precision Extruded Profile

6-series T5 aged aluminum alloy base undergoes integrated forging to sustain heavy load of full-size floor glass, with uniform 8mm thick solid cross-section. Cross diagonal inner supports disperse lasting weight from large glass panels. Polyester powder film outer coating resists coastal salt mist and rainy-region surface pulverization. Frames and sashes are produced via exclusive matching molds with precise dimensional error control, delivering even gaps for multi-panel linkage without frame distortion after years of frequent sliding.

❷Single-Joint Closed-Loop CNC Bent Hollow Aluminum Spacer

Instead of widely used segmented aluminum separators, CNC integrated bending creates a seamless closed-loop support structure with only one double butyl sealing layer to block external moisture penetration. Thickened aluminum structure fits thermal expansion of 27mm wide air cavity to prevent glue separation. Moisture-absorbing particles filled inside continuously remove residual vapor between glass layers, eliminating inner fogging and water droplets caused by temperature fluctuation.

❸Extra-Wide Cavity Tempered Safety Insulated Glass

All sets are equipped with 5-layer wide sound-insulating tempered viewing glass passing national mandatory safety test, filled with high-purity argon medium inside interlayer. The widened air layer weakens outdoor noise transmission and blocks cross flow of hot and cold air. Optional offline single-silver thermal coating blocks infrared heat in summer and retains indoor heat in winter to cut HVAC energy loss. Finely rounded glass edges wrapped with flexible anti-collision wrapping avoid breakage during transport, and broken glass forms blunt particles to prevent household scratches.

❹Triple Staggered Composite Track Sealing Wool Piles

Three layers of staggered flexible dust-proof wool strips are laid at overlapping track zones between sash and fixed frame. PET reinforcing film at strip roots solves lodging, fiber shedding and elasticity loss after long-term sliding. Interleaved multi-layer structure fills multi-grade track gaps, buffers harsh noise from hard aluminum friction and blocks outdoor dust, sand and cold air. Weather-modified PP raw material avoids hardening and shrinkage under long sunlight to retain stable sealing elasticity with low maintenance demand.

❺Sunken Arched Load-Bearing Silent Sliding Track

Sunken embedded track structure removes protruding steps to prevent tripping risks for elders and children. One-piece cast track with arched bottom supports evenly shares total weight of combined multi-panel sashes without long-term sagging or local deformation. Double rows of low-friction shock-absorbing bearing rollers deliver smooth sliding with light resistance, built-in left-right limit buckles stop sash side-slip and derailment under strong wind. Anti-abrasion protective coating on track surface guarantees smooth sliding without jamming noise after tens of thousands of cycles.

❻Graded Diversion Concealed Full-Range Water Drainage System

Stepwise layered diversion bins inside profiles guide infiltrated rainwater into independent water collection cavities by gravity to avoid overflow and corrosion of internal transmission hardware. Hidden drain openings on outer profiles fitted with dust & rainproof decorative caps keep minimalist neat facade without exposed apertures. Hydrophobic protective film on channel inner walls prevents sludge clogging and accelerates rainwater discharge during heavy rain, fundamentally eliminating backflow and cavity leakage risks.

❼14.8mm Full-Length Glass-Fiber Reinforced PA66 Thermal Break Strips

Full-frame laid 14.8mm widened glass-fiber filled nylon thermal isolation layers evenly mixed with 25% alkali-free glass fiber to restrain high-temperature creep and low-temperature brittle shrinkage, fully cutting off metal heat conduction paths between inner and outer aluminum layers. Cooperated with full-perimeter EPDM elastic edge strips to form composite thermal insulation system, it drastically slows indoor-outdoor heat loss, stabilizes constant indoor temperature in extreme seasons and greatly reduces HVAC operating power consumption.

❽Narrow Frame Custom Linkage Multi-Point Anti-Corrosion Hardware

Whole set of locking transmission components are custom-molded exclusively for ultra-narrow sliding structure, with zinc alloy base and multi-layer passivation anti-oxidation coating to resist oxidation and jamming in high-salt coastal and humid balcony environments. Side multi-point synchronous locking structure presses the sash evenly from all directions to eliminate air and water leakage gaps. Recessed hidden handles preserve minimalist facade aesthetics, and detachable wearing parts like rollers and lock points cut long-term whole-door maintenance expenses effectively.
