This article documents pricing ranges, material specifications, performance ratings, certifications, procurement parameters, and installation data for aluminum alloy door and window systems.
Aluminum Doors and Windows Pricing Structure
Factory Pricing by System Type
Pricing is quoted per square meter of opening area, FOB Foshan, based on 6063-T5 aluminum profiles, double glazed units, and standard hardware. The table below lists base prices before volume discounts.
Volume Discount Tiers
Hardware upgrades (multi-point locks, friction stays, lift-and-slide tracks) add USD 12-45 per unit. Wood-grain sublimation finish adds USD 18-32/m2. Anodized finish adds USD 8-15/m2.
Aluminium Windows and Doors: Material Specifications
Alloy Grades and Extrusion Parameters
All ROGENILAN aluminum doors and windows use 6063-T5 and 6063-T6 alloy extrusions. The table below documents the metallurgical and extrusion parameters.
Surface Treatment and Spray Coating
Profiles undergo pre-treatment (degreasing, alkali etching, chromate conversion) before coating. Three finish systems are standard:
Thermal Break Strip Specifications
Thermal break strips separate the interior and exterior aluminum profiles to reduce heat transfer. ROGENILAN uses polyamide 66 (PA66) strips reinforced with 25% glass fiber.
Windows and Doors Performance Ratings
U-Value and Thermal Performance
U-values are measured per GB/T 8484 (Chinese standard) and EN ISO 10077-1 (European). The table below lists performance data by glass configuration.
Structural and Weather Performance
Aluminum doors and windows are tested per GB/T 7106 for wind resistance, water tightness, and air permeability. Performance grades:
Doors and Windows Certifications
International Certification Standards
ROGENILAN aluminum doors and windows carry the following certifications:
Test Documentation Requirements
Each production batch ships with a mill test certificate documenting alloy composition (Si 0.40%, Mg 0.68%, Fe 0.20%), mechanical properties, coating thickness, and weather performance test results. Third-party test reports from SGS, TUV, or Intertek are available on request with a 7-day lead time.
Procurement, MOQ and Packaging for Windows and Doors Aluminum
Order Quantities and Lead Times
Payment Terms and Packaging Specs
Packaging: profiles wrapped in PE film, glass units separated by EPE foam boards, hardware packed in individual cartons. Complete units loaded into steel racks inside 20GP or 40HQ containers. A 20GP container holds approximately 500-800 m2 of window/door units; a 40HQ holds 1,200-1,800 m2.
Aluminum Extrusion Manufacturing Process
Extrusion Line Parameters
The manufacturing process for aluminum doors and windows begins with billet casting and extrusion. ROGENILAN operates two 1800-ton and one 2500-ton extrusion presses. Key parameters:
Cutting, Machining and Assembly
After aging, profiles are cut to length using CNC double-miter saws (accuracy +/- 0.2mm). Machining operations include:
- Drainage groove milling: 5mm x 20mm slots at 300mm intervals
- Hardware groove milling: euro-groove (16mm) or multi-groove profiles per system
- Gasket groove routing: continuous EPDM gasket channel
- Punching for fixed points: 8mm holes at 400mm centers
- CNC corner crimping: 4-head automatic crimping machine, 40-60 kN force per corner
Assembly tolerance: frame diagonal deviation max 2mm per 1000mm. Corner joint gap max 0.15mm. All assembled frames undergo squareness inspection before glazing.

Gasket and Sealant Specifications
EPDM gaskets are tested per GB/T 528 for tensile strength (12 MPa min), elongation at break (250% min), and compression set (25% max after 70 hr at 100C). Silicone sealants meet GB/T 14683 Type S (structural) or Type F (non-structural) requirements.
Installation Technology and Project Case
Installation Steps
Installation follows a 6-step procedure documented in the ROGENILAN installation manual:
- Opening preparation: Verify opening dimensions (+/-3mm tolerance), clean concrete surfaces, apply waterproofing membrane to sill.
- Frame positioning: Place frame in opening with 10mm expansion gap per side. Use steel shims at corners and load points.
- Fixing: Secure frame with expansion bolts or chemical anchors at 400mm centers. Torque to 25 Nm.
- Sealing: Inject low-modulus silicone sealant between frame and wall. Apply weatherproofing tape over sealant joint.
- Glazing installation: Insert glass units with EPDM gaskets. Set bearing blocks at quarter points. Install pressure plates at 150mm centers.
- Commissioning: Test operation (force 100N max for sliding, 80N max for casement). Verify water drainage weep holes are clear. Conduct spray test at 500 Pa for 15 minutes.
Case Study: Dubai Residential Tower (2025)
A 24-floor residential tower in Dubai Marina installed 3,200 m2 of ROGENILAN aluminum doors and windows in 2025. The project used casement windows (6063-T5, 1.6mm, 34mm thermal break) with 5+27A+5 Low-E + argon glass to meet Dubai Municipality thermal requirements.
The client also sourced aluminum sliding windows for balcony areas and aluminum entrance doors for the lobby from the same production line, consolidating quality control and reducing freight cost per m2.

Cost Lifecycle Analysis (20-year, 100 m2 project)
For projects requiring large glazing spans (sash over 2.0 m2), hurricane-rated performance, or 30+ year service life, aluminum doors and windows provide the lowest total cost of ownership despite higher initial price. The fire-rated A1 classification and 100% recyclability also align with LEED and BREEAM project requirements.
For complementary product lines, ROGENILAN also manufactures aluminum doors and windows systems and aluminium sunroom and wintergarten structures using the same 6063-T5 alloy and thermal break technology.
