Exterior Doors for Houses: Pricing & Configuration Options

China exports approximately 120 million door units annually, with exterior doors accounting for 28% of total door exports by value. Factory-direct pricing for aluminum exterior doors ranges from $280 to $850 per unit, depending on frame configuration, glass type, and hardware specifications. The table below breaks down pricing by configuration.

Configuration	Frame Material	Glass Type	Price/Unit (FOB)	MOQ
Single Door (900×2100mm)	6063-T5 Aluminum, 2.0mm	5mm+12A+5mm Tempered	$280–$360	10
Single Door + Sidelight	6063-T5 Aluminum, 2.0mm	5mm+12A+5mm Low-E	$420–$520	10
Double Door (1800×2100mm)	6063-T5 Aluminum, 2.2mm	6mm+16A+6mm Tempered	$580–$720	5
Double Door + Sidelights + Transom	6063-T6 Aluminum, 2.2mm	6mm+16A+6mm Triple-Silver Low-E	$720–$850	5

Frame thickness options range from 1.8mm to 2.2mm. The 2.0mm wall thickness meets AAMA 101 performance class for commercial applications. Powder coating adds $15–$25 per square meter surface area. Wood-grain transfer finish adds $35–$50 per door.

Door Core Construction Types

Three core types are available for exterior doors for houses applications:

Polyurethane (PU) foam-filled: Density 38–42 kg/m³, U-value 0.35–0.45 W/m²K. R-value of R-6 to R-8. Suitable for IECC Climate Zones 1–5.
EPS foam-filled: Density 16–20 kg/m³, U-value 0.45–0.55 W/m²K. Cost approximately 18% less than PU.
Honeycomb aluminum core: Density 28–32 kg/m³, U-value 0.50–0.60 W/m²K. 40% lighter than foam-filled panels, preferred for pivot door applications.

Hardware Configuration Tiers

Tier	Lock System	Hinges	Handle Material	Add-on Cost

Exterior Pivot Door Modern: Manufacturing Process & Material Specifications

The exterior pivot door modern design uses a floor-mounted or top-mounted pivot hinge system that shifts the door’s rotation axis away from the frame edge. This allows for panel widths up to 1400mm and heights up to 3200mm using stable aluminum frame construction.

Aluminum Alloy Specifications

Parameter	Standard Configuration	Heavy-Duty Configuration
Alloy Grade	6063-T5 (GB/T 5237)	6063-T6 (GB/T 5237)
Tensile Strength	≥160 MPa	≥205 MPa
Yield Strength	≥110 MPa	≥180 MPa
Elongation	≥8%	≥10%
Wall Thickness	2.0mm ±0.05mm	2.2mm ±0.05mm
Max Panel Width	1200mm	1400mm
Max Panel Height	2800mm	3200mm
Max Weight Capacity	200 kg	300 kg

Surface Treatment Process

All frames undergo a 7-stage pre-treatment line before powder coating:

Alkaline degreasing (pH 11–12, 55°C, 3 min)
Water rinse (ambient, 1 min)
Acid etching (pH 2–3, 30°C, 2 min)
Water rinse (ambient, 1 min)
Chromium-free conversion coating (Zr/Ti based, 30°C, 1 min)
Water rinse (ambient, 1 min)
Forced air drying (80°C, 5 min)

Powder coating uses polyester-based powder (AkzoNobel or Tiger Drylac) applied at 60–80 kV electrostatic voltage, cured at 200°C for 10 minutes. Coating thickness: 60–80 μm. Salt spray resistance: ≥1,000 hours (ASTM B117). UV resistance: ΔE ≤ 5 after 3,000 hours QUV-B (ASTM G154).

Thermal Break Technology

Polyamide 66 (PA66) thermal break strips with 25% glass fiber reinforcement are inserted between inner and outer aluminum profiles. Strip width options:

Strip Width	Frame U-Value	Application
14.8mm	2.8–3.2 W/m²K	Mild climates (Zone 1–3)
20mm	2.2–2.6 W/m²K	Temperate climates (Zone 4–5)
24mm	1.8–2.2 W/m²K	Cold climates (Zone 6–7)
34mm (multi-chamber)	1.4–1.8 W/m²K	Extreme cold / Passive House

Aluminum Entrance Door: Technical Performance Data

Glass Configuration & Thermal Performance

Glass Package	Makeup	U-Value	SHGC	VT	STC
Standard Double	5mm Clear + 12A + 5mm Clear	2.7	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(#2) + 12A + 5mm Clear + 12A + 5mm Low-E(#5)	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 (Super Spacer or Swisspacer) add approximately 0.02–0.04 W/m²K improvement at the edge zone.
