Chang Yi NFRC Certified Aluminum Sliding Glass Door Heavy Duty Load Bearing Double

Product Description

We are a professional manufacturer of aluminum sliding doors, the space-saving gliding door solution for patios, balconies and room partitions. Featuring 6060-T6 thermal break profiles, heavy-duty stainless steel rollers and multi-point locking, our sliding doors glide smoothly with large glass panels for panoramic views and natural light. Available in single, double and multi-panel configurations with optional low threshold, fly screen and lift & slide systems. Fully customizable in size, color and glazing. NFRC certified, OEM/ODM supported. Contact us for a quotation, or send your drawings for a custom quote.

Key Features

1. Space-Saving Gliding Design — the door slides horizontally along the track, occupying no interior or exterior space — ideal for patios and balconies.

2. Smooth & Quiet Operation — heavy-duty stainless steel bearing rollers glide quietly and smoothly, built for frequent daily use.

3. Large Glass Panels — big glazing areas provide panoramic views and abundant natural light.

4. Thermal Break Energy Efficiency — PA66GF25 thermal break profiles with optional Low-E or triple glazing achieve a U-Factor as low as 1.2 W/(m²·K).

5. Multi-Point Locking Security — multi-point locks with anti-lift blocks prevent prying and panel lifting.

6. Weather Resistance — EPDM gaskets and weatherstripping brush seals keep out wind, rain and dust, with high water tightness.

7. Optional Low Threshold — level-access threshold allows barrier-free passage for wheelchairs, strollers and elderly users.

8. Flexible Configurations — single, double and multi-panel designs; fly screen, lift & slide and fixed + sliding combinations available; OEM/ODM supported.
