Engineered Aluminum Sliding Windows for Overseas Projects
Grandor Door Industry Co., Ltd. manufactures commercial and residential thermal-break aluminum sliding windows engineered for effortless operation, weather durability, and high energy efficiency.
Precision Engineering & Global Compliance
Manufactured inside our 155,000 m² smart facility, our aluminum sliding window systems are tailored to meet stringent international building standards. By incorporating high-density polyamide thermal break strips, multi-cavity profile structures, and heavy-duty stainless steel track rollers, Grandor sliding windows provide smooth operation across wide sash spans without compromising on thermal insulation or acoustic control.
Whether your project requires standard 2-track sliding sashes, 3-track systems with integrated stainless steel security mesh, or minimal slim-frame architectural sliding windows, every sash is extruded, powder-coated, double-glazed, and performance-tested under one roof.
- Compliant with AS2047, CE EN 14351-1, and ASTM E283/E330/E547 testing standards.
- 6063-T5 architectural aluminum alloy profiles with 1.4mm to 2.0mm structural wall thickness.
- Insulated Low-E tempered glass, argon gas filling, and acoustic PVB laminated options available.

Why Global Importers & Builders Choose Our Sliding Windows
Designed to solve core challenges in high-density residential apartments, coastal villas, and commercial developments.
Thermal Break Insulation
High-density polyamide strips separate inner and outer aluminum frames, cutting heat conduction and reducing HVAC energy usage in hot and cold climates.
Smooth Track & Roller System
Precision tandem stainless steel rollers combined with heavy-duty aluminum tracks deliver whisper-quiet gliding for large double-glazed sashes up to 250kg.
Multi-Point Security Locking
Integrated multi-point hardware locks the window frame firmly along multiple latch points to provide enhanced forced-entry prevention and wind-load stability.
System Specifications & Custom Options
Configurations can be custom engineered based on your project drawings, structural requirements, and local climate needs.

Surface Coating
Automated powder coating and anodizing lines offering salt spray corrosion resistance.
Pre-Shipment Testing
Full window mock-up assembly, seal compression test, roller testing, and export plywood packing.
Frequently Asked Questions for Project Buyers
Practical details for architects, contractors, importers, and building material distributors.
Can Grandor customize aluminum sliding windows to meet local building codes?
Yes. We routinely manufacture sliding window packages compliant with Australian standards (AS2047 / AS1288), North American NFRC/ASTM ratings, and European CE EN 14351-1 requirements. Our engineering team reviews wind pressure requirements, glass thickness, and thermal target values before finalizing shop drawings.
What is the typical production lead time for container orders?
Standard manufacturing lead time is 25 to 35 days following shop drawing confirmation and deposit receipt. Scheduled phased container shipments can also be arranged for large commercial projects.
How do you ensure window finishes resist coastal weather conditions?
We use Qualicoat-certified architectural powder coatings and high-performance PVDF coatings designed to withstand high humidity, coastal salt spray, and heavy UV exposure. Salt spray test reports are available upon request.
What packing method is used to protect glass and frame profiles in transit?
All sashes and frames are wrapped in protective PE film, protective corner caps, bubble wrapping, and sealed inside IPPC-certified export plywood crates to prevent scratches and moisture ingress during ocean freight.
