Accordion Door Manufacturer in China – Custom Aluminum Folding Solutions
Accordion Door Manufacturer in China – Custom Aluminum Folding Solutions
Accordion doors, also known as aluminum folding doors or bi-fold doors, are space-efficient opening systems widely used in residential, commercial, and hospitality projects. As a specialized accordion door manufacturer in China, ROGENILAN produces custom aluminum folding door systems with thermal break technology, meeting CE, NFRC, and AAMA certification standards. This article presents technical specifications, production data, pricing, and installation requirements for aluminum folding door projects.
Accordion Door Specifications and Technical Data
Aluminum Alloy Profile and Wall Thickness
ROGENILAN accordion door frames use 6063-T5 aluminum alloy with a minimum wall thickness of 1.6mm for main profiles and 1.4mm for auxiliary profiles. The 6063-T5 alloy provides a tensile strength of 160 MPa and yield strength of 110 MPa, suitable for spans up to 6 meters in folding configurations. The extrusion tolerance complies with GB/T 5237.1-2017 Class A standards.
Standard profile dimensions for accordion door systems:
Thermal Performance and U-Values
Thermal break accordion door systems use PA66 GF25 polyamide insulation strips with a width of 24mm. The thermal break assembly reduces heat transfer by separating the interior and exterior aluminum profiles. Tested U-values range from 1.4 to 2.1 W/(m²·K) depending on glass configuration:
Aluminum Folding Door Production Process
Extrusion and Surface Treatment
Raw aluminum billets are heated to 480°C and extruded through dies at 300-350 MPa pressure. After extrusion, profiles undergo aging treatment at 185°C for 6 hours to achieve T5 temper. Surface treatment options include:
- Anodized: 10-20 micron thickness, AA15 grade, color options: natural silver, champagne, bronze, black
- Electrophoretic coating: 12-18 micron film thickness, matte or gloss finish
- PVDF fluorocarbon coating: 35-40 micron total thickness, 20-year color retention warranty
- Powder coating: 60-80 micron thickness, RAL color matching available
The powder coating process uses epoxy-polyester hybrid powder cured at 180-200°C for 15 minutes. Salt spray testing exceeds 1000 hours per ASTM B117.
Thermal Break Assembly
PA66 GF25 insulation strips are inserted into profile grooves and crimped using a rolling machine with 3-5 tons pressure. The strip width determines the thermal break performance: 14.8mm for standard applications, 24mm for cold climates, and 34mm for passive house projects. The combined profile after thermal break assembly must pass a shear strength test of ≥24 N/mm.
