- Tilt-in sash for indoor cleaning
- Traditional aesthetic look
Aluminum Folding Windows
Bi-fold multi-panel sashes that fold seamlessly to one side, opening up full pass-through spaces for modern indoor-outdoor living environments.
- Smooth top-hung roller track
- Low threshold floor transition
- Custom panel count up to 7 sashes
Skylight Roof Windows
Heavy-duty roof glazing systems built to withstand snow loads and torrential storms. Available in fixed or electric motorized configurations.
- Reinforced structural aluminum alloy
- Laminated safety solar glass
- Smart sensor & remote controls
Why Global Importers Choose Grandor Aluminum Windows
Integrated raw material extrusion, glass tempering, and precision assembly inside our 155,000 m² facility remove supply chain friction.
6063-T5 Profile Extrusion
Architectural aluminum alloys extruded in-house ensure uniform wall thickness (1.4mm - 2.0mm), structural rigidity, and resistance to environmental stress.
Polyamide Thermal Barriers
High-density PA66 nylon thermal break strips divide exterior and interior profiles, cutting heat transmission and reducing HVAC energy load.
Insulated Glazing Units
In-house tempered, Low-E coated, argon gas-filled double or triple glazing packages optimized for UV protection, safety, and acoustic dampening.
Surface Treatment Durability
Advanced electrostatic powder coating and anodizing lines resist corrosion, color fading, and salt spray in coastal harsh climates.
Multi-Point Security Locks
Equipped with premium hardware systems that lock sashes into heavy steel keepers at multiple frame points to prevent forced entry.
Project Specification Support
Our engineering team provides structural calculations, CAD shop drawings, and custom color matching for builders, architects, and wholesalers.
