China exports approximately 4.2 billion square meters of aluminum windows annually, with Foshan Guangdong Province accounting for roughly 35% of total export volume. This article provides technical specifications, production process data, certification requirements, and export pricing for ventanas (aluminum windows) manufactured in China. Data is based on factory audits, product testing reports, and export order records from manufacturers serving Latin America, North America, Europe, and the Middle East.
The ventanas de aluminio y cristal category covers aluminum-framed windows with glass infill. These systems are the most common export format from China due to their balance of structural performance, thermal efficiency, and cost.
Standard residential window sizes exported from China follow modular dimensions. Common widths range from 600mm to 2400mm; heights from 600mm to 2100mm. The following table shows FOB China pricing by window type and size.
| Window Type | Width x Height (mm) | Glass Config | Unit Price (USD) | MOQ |
|---|---|---|---|---|
| Single casement | 600 × 1200 | 5+12A+5 tempered | $85–$120 | 10 |
| Double casement | 1200 × 1200 | 5+12A+5 tempered | $140–$195 | 10 |
| Sliding window | 1500 × 1200 | 5+9A+5 tempered | $125–$175 | 10 |
| Fixed picture | 1800 × 1500 | 5+12A+5 tempered | $160–$220 | 8 |
| Bay window | 2400 × 1500 | 5+12A+5 Low-E | $320–$450 | 5 |
Primary frame profiles for ventanas de aluminio y cristal use 6063-T5 aluminum alloy. Minimum wall thickness is 1.4mm for outer frames, 1.6mm for sash frames, and 2.0mm for mullions and transoms. Frame depth ranges from 50mm to 70mm depending on the series. Thermal break profiles use PA66 GF25 polyamide strips with widths of 14.8mm, 18.6mm, or 24mm.
The production process for ventanas de aluminio in China follows a standardized sequence. Each step has associated quality control checkpoints.
Profiles are extruded from aluminum billets (AA6063 or AA6061). Extrusion press capacity ranges from 800T to 2500T depending on profile cross-section. After extrusion, profiles undergo online quench followed by aging:
Each batch is accompanied by a mill certificate specifying alloy grade, tensile strength, yield strength, and elongation (≥8%).
Two coating systems are available for ventanas de aluminio:
| Process | Coating Thickness | Adhesion (cross-cut) | Salt Spray Resistance | Warranty |
|---|---|---|---|---|
| Powder Coating (polyester) | 60–80 micron | Class 0 | 1000h (ASTM B117) | 10 years |
| PVDF (fluorocarbon 3-coat) | 30–40 micron total | Class 0 | 4000h (ASTM B117) | 20 years |
| Anodizing | 10–20 micron | Class 0 | 500h (ASTM B117) | 5 years |
For coastal projects within 500m of saltwater, PVDF coating is mandatory. Powder coating is sufficient for inland applications. Wood-grain transfer finish adds $8–$15 per square meter surface area.
Polyamide 66 (PA66) thermal break strips with 25% glass fiber reinforcement are roll-pressed into the aluminum profile cavity. Strip width options and resulting frame U-values:
| Strip Width | Frame U-Value | Application |
|---|---|---|
| 14.8mm | 2.8–3.2 W/m²K | Mild climates |
| 18.6mm | 2.2–2.6 W/m²K | Temperate climates |
| 24mm | 1.8–2.2 W/m²K | Cold climates |
| 34mm (multi-chamber) | 1.4–1.8 W/m²K | Passive House / extreme cold |
Ventanas de aluminio correderas (sliding aluminum windows) use horizontal sash movement on nylon or stainless steel rollers. This configuration is preferred for projects requiring space-efficient operation and large glass areas.
Testing for sliding aluminum windows follows EN 12207, EN 12208, and EN 12210 standards. Data below is from third-party laboratory testing.
| Test Parameter | Standard | Result | Rating |
|---|---|---|---|
| Air Permeability | EN 12207 (100 Pa) | ≤0.5 m³/h·m | Class 4 |
| Water Tightness | EN 12208 (300 Pa) | No leakage at 600 Pa | Class 8A |
| Wind Load Resistance | EN 12210 | ±1800 Pa | Class B5 |
| Thermal Transmittance | NFRC 100 | U=1.8 W/m²K (24mm PA66) | Energy Star Zone C |
| Acoustic Insulation | ISO 140-3 | 32–38 dB | Class 3–4 |
Ventanas de aluminio corredizas refers to horizontal sliding window systems. These are functionally similar to correderas but often specify wider frame profiles and heavier-duty hardware for commercial or high-rise applications.
| Series | Frame Depth | Wall Thickness | Max Sash Size | Application |
|---|---|---|---|---|
| 50 Series | 50mm | 1.4mm | 1200 × 1500mm | Residential |
| 60 Series | 60mm | 1.6mm | 1500 × 1800mm | Residential / light commercial |
| 70 Series | 70mm | 1.8mm | 1800 × 2400mm | Commercial |
| 80 Series | 80mm | 2.0mm | 2000 × 3000mm | High-rise / hurricane zones |
| Glass Package | Makeup | U-Value (W/m²K) | SHGC | VT | STC |
|---|---|---|---|---|---|
| Standard Double | 5mm Clear + 12A + 5mm Clear | 2.8 | 0.70 | 0.78 | 31 |
| Low-E Double | 5mm Low-E(#2) + 16A + 5mm Clear | 1.8 | 0.42 | 0.70 | 32 |
| Triple Glazed | 5mm Low-E + 12A + 5mm Clear + 12A + 5mm Low-E | 1.1 | 0.35 | 0.62 | 36 |
| Laminated Triple | 6mm Laminated Low-E + 16Ar + 5mm Clear + 16Ar + 6mm Laminated | 0.9 | 0.32 | 0.58 | 40 |
Argon gas fill (90% minimum concentration) reduces center-of-glass U-value by approximately 16% compared to air-filled units. Warm-edge spacers (Swisspacer or TGI-Spacer) add approximately 0.02–0.04 W/m²K improvement at the edge zone.
