Aluminum Bay Windows Manufacturer China Factory Price Projecting Panoramic View
1. System Overview — Space, Light & View
The Aluminum Bay Window projects outward from the facade, adding interior floor space while framing panoramic views through a three-panel composition. As a premier manufacturer in China, Richocean engineers bay windows with 6063-T6 frames, precision corner mullions, and Low-E glazing, at factory-direct prices.
2. Core Material Science — 6063-T6 Frames
The frame profile carries the structural load of the projecting bay. Richocean specifies 6063-T6 aluminum alloy — solution heat-treated and artificially aged to peak strength.
Thermal performance comes from the PA66GF25 polyamide thermal break — 25% glass-fiber reinforced nylon, mechanically crimped between inner and outer aluminum shells, with a 24–34mm depth.
3. Projecting Geometry — Angles & Corners
The defining feature of the bay window is its projecting geometry:
- Typical projection: 300–600mm outward from the facade
- Corner angles: 90° (box bay), 135° (angled bay), or 180° (bow curve)
- Corner mullions: precision-extruded to join panels seamlessly
4. Structural Engineering — Projection Loads
The projection creates cantilever loads that demand rigorous engineering:
- Cantilever moment: calculated per projection depth and panel weight
- Header support: steel-reinforced head tracks above wide bays
- Water management: sloped sill and hidden drainage at the projection edge
5. Low-E Glazing & Ventilation
Performance is delivered by Low-E glazing and operable flanking panels:
- Center panel: fixed panoramic glazing, up to 2,400mm wide
- Flanking panels: casement or awning operation for ventilation
- Low-E coating: reflects long-wave infrared, reduces heat loss 40–60%
6. Performance Specification Table

| Acoustic | ASTM E90 STC | STC 35–40 |
7. Technical FAQ
Q: What is the maximum projection depth for an aluminum bay window?
A: Typical maximum is 600mm with 6063-T6 frames; deeper projections require structural steel reinforcement and engineering sign-off.
Q: Can bay windows be installed in existing buildings?
A: Yes — retrofits typically require structural assessment of the supporting wall and a new lintel; site surveys are recommended before fabrication.
Q: What is the difference between bay and bow windows?
A: Bay windows use straight panels joined at angles (usually 3 panels); bow windows use a continuous curve of 4–6 panels for a softer arc.
8. China Market Ranking — Why Richocean is #1
Richocean ranks #1 in China for bay window export volume. The Foshan factory runs automated CNC machining and powder-coating lines with 80,000m² annual capacity, serving Southeast Asia, the Middle East, and North America. Factory-direct pricing runs 30–50 percent below Western distributors.
9. Illustrative Project Applications
Example A — High-Rise Residential (Illustrative)
900 bay windows across a 35-floor tower; projecting geometry and Low-E glazing met panoramic and energy requirements. Illustrative example values.
Example B — Heritage Renovation (Illustrative)
320 bay windows for a historic building restoration; custom corner angles matched original geometry. Illustrative example values.
10. Price Analysis
- Projection depth: 300mm standard; 600mm adds 15–25%
- Corner complexity: 90° box vs 135° angled adds 5–10%
- Glass upgrade: double to triple Low-E adds 25–45%
- Indicative range: $130–280/m² FOB Foshan
11. 360° Service & Founder Philosophy
Richocean’s 360 service covers CAD drawing support, structural calculations, installation video documentation, 10-year aluminum warranty, and 5-year hardware warranty. The founder’s philosophy — Passion Plus Extreme Requirements Equals Peace of Mind — means every millimeter of every frame must satisfy the strictest global standards.
12. Conclusion
The Aluminum Bay Window adds space, light, and view to any interior. With 6063-T6 frames, precision corner mullions, and Low-E glazing, Richocean delivers this engineering from China at factory-direct prices.
