Architectural-Grade Aluminum Casement Doors
Grandor Door Industry Co., Ltd. manufactures factory-direct aluminum casement doors engineered with high structural integrity, superior thermal breaks, and multi-point security locking systems to fulfill strict international building standards.
Aluminum casement doors (also known as hinged aluminum doors or French doors) provide classic operation paired with modern performance technology. Engineered with 6063-T5 high-tensile aluminum profiles, our casement door systems deliver robust frame strength, outstanding weather tightness, and smooth, long-lasting hinge performance.
Whether specified for luxury villas, commercial office entrances, or patio access, Grandor aluminum casement doors feature advanced thermal barrier technology and double or triple Low-E insulated glass, significantly reducing heat transfer and acoustic infiltration across all climate zones.
Thermal Break Efficiency
Equipped with high-precision PA66 polyamide insulating strips to prevent thermal bridges, reduce energy bills, and stop interior condensation.
Multi-Point Security
Engineered with multi-point stainless steel locking systems and anti-pry hardware for exceptional intrusion resistance.
Weather Tight Seals
Dual and triple EPDM continuous gasket sealing ensures superior airtightness, water tightness, and noise reduction up to 42 dB.
Custom Architectural Finishes
Available in durable powder coatings, anodized finishes, PVDF coatings, and realistic Italian heat-transfer wood grain effects.

Frequently Asked Questions
Key information for overseas importers, contractors, and project managers procuring aluminum casement doors from China.
What are the structural advantages of Grandor aluminum casement doors?
Grandor aluminum casement doors utilize 6063-T5 architectural-grade aluminum extrusions with high wall thickness (1.8mm–3.0mm), combined with polyamide PA66 thermal breaks and heavy-duty multi-point hardware for superior structural stability, wind resistance, and thermal insulation.
Can aluminum casement doors be customized for specific climate zones and building codes?
Yes. Every door profile, thermal break depth, glass build-up (such as double or triple Low-E insulated glass, argon gas filling, and laminated safety glass), and hardware brand can be engineered to comply with AS2047, NFRC, CE, and ASTM specifications.
What hardware options are supplied with your casement doors?
We offer premium European concealed hinges, heavy-duty surface hinges, multi-point lock bodies, anti-burglary cylinder locks, and smart digital locking options sourced from leading brands or engineered in-house.
What is the typical production lead time for wholesale project orders?
Standard manufacturing lead time is approximately 25 to 35 days from approved shop drawings, supported by our integrated 155,000 m² production facility.
