Doors for Houses Wholesale in China — Aluminum Door Specs, Pricing & Procurement Data

Aluminum doors for houses from China factories deliver thermal break performance, CE/AAMA certification, and configurable profiles at wholesale pricing between $85 and $350 per square meter. This article breaks down alloy grades, profile wall thickness, U-value ranges, certification requirements, and procurement terms for residential door projects — from single front door units to multi-unit bulk orders.

Aluminum Doors for Houses: Alloy Grades & Profile Specifications

6063-T5 vs 6063-T6 Alloy Properties

Chinese aluminum door manufacturers primarily use 6063-T5 and 6063-T6 alloy profiles. The difference affects yield strength and application suitability:

Property	6063-T5	6063-T6
Yield Strength (MPa)	110	180
Tensile Strength (MPa)	145	230
Hardness (HW)	≥8	≥13
Typical Application	Standard residential doors	High-load entry doors, windzone 3+
Cost Premium	Base	+5-8% over T5

For standard residential doors for houses in non-hurricane zones, 6063-T5 meets structural requirements at lower cost. Projects in coastal or high-wind regions should specify 6063-T6.

Profile Wall Thickness & Thermal Break Width Standards

Chinese national standard GB/T 5237 and international norms define minimum wall thickness for residential aluminum door profiles:

Door Type	Min. Wall Thickness (mm)	Thermal Break Width (mm)	Typical U-Value Range (W/m²K)
Single entry door	1.4	14.5-18	2.8-3.5
Double entry door	1.6	18-24	2.2-2.8
Interior door (non-thermal)	1.2	N/A	5.0-6.5
Sliding patio door	1.6	18-24	2.0-2.6
Folding/bifold door	2.0	24-28	1.8-2.4

Thermal break strips use PA66-GF25 (polyamide 66 with 25% glass fiber). Strips narrower than 14.5mm reduce thermal performance below EN 12631 Class C thresholds. For doors for houses requiring passive house certification, specify 24mm+ thermal break width with triple glazing.

Front Door Configurations: Pricing Tables & Size Options

Single & Double Front Door Price Breakdown

Wholesale pricing from Foshan aluminum door factories varies by configuration, glass type, and hardware grade. Below are factory-direct price ranges for standard residential front door configurations:

Configuration	Size Range (mm)	Glass Option	Price Range (USD/m²)	Unit Price Estimate (USD)
Single door, single glass	900×2100	5mm tempered	$85-120	$160-225
Single door, double glazed	900×2100	5+12A+5	$120-180	$225-378
Single door, triple glazed	900×2100	5+9A+5+9A+5	$180-260	$378-546
Double door, double glazed	1800×2100	5+12A+5	$140-200	$529-756
Double door with sidelight	2400×2100	5+12A+5 Low-E	$200-350	$1,008-1,764

Prices include thermal break aluminum frame, powder coating (standard colors), basic hardware lock set, and factory assembly. Shipping, custom color matching, and premium hardware (multi-point lock, electronic access) add 15-30% to base pricing.

Hardware & Accessory Cost Adders

Hardware selection impacts both cost and security rating for front door units:

Hardware Category	Base Option (USD)	Mid-Range (USD)	Premium (USD)
Lock set (single point)	$8-15	N/A	N/A
Multi-point lock (3-5 points)	N/A	$25-45	$55-80
Electronic smart lock	N/A	N/A	$120-280
Handle set	$5-12	$15-30	$35-65
Hinges (pair)	$3-8	$10-20	$25-50
Door closer	$6-15	$18-35	$40-75

Metal Doors for Houses: Steel vs Aluminum Performance Comparison

Structural & Thermal Performance Data

When sourcing metal doors for houses, the steel vs aluminum decision affects weight, thermal performance, corrosion resistance, and total cost. Data comparison:

Parameter	Aluminum (Thermal Break)	Steel (Insulated)	Steel (Non-Insulated)
Frame Weight (kg/m²)	3.5-5.0	12-18	10-15
U-Value (W/m²K, double glazed)	2.2-2.8	1.8-2.5	5.5-7.0
Wind Load Resistance (Pa)	2000-3000	3000-5000	2500-4000
Air Permeability (m³/h·m)	≤1.5 (Class 4)	≤1.0 (Class 4)	≤2.5 (Class 3)
Water Penetration (Pa)	≥300	≥350	≥200
Corrosion Resistance	Anodized/powder coat 15-25yr	Galvanized 8-12yr	Rust-prone without coating
Price (USD/m², base)	$85-200	$65-140	$40-80

Aluminum thermal break doors achieve U-values competitive with insulated steel at 35-60% lower frame weight — reducing structural load and installation labor. Steel doors offer higher wind load resistance but require periodic anti-corrosion maintenance in humid or coastal climates.

Coating & Surface Treatment Specifications

Surface treatment determines both aesthetics and durability for metal doors for houses:

Treatment	Standard	Thickness	Color Options	Guarantee Period	Cost Adder
Powder Coating	Qualicoat Class 1	40-80μm	200+ RAL colors	10-15 years	Base
Powder Coating (Class 2)	Qualicoat Class 2	60-120μm	200+ RAL + wood grain	15-25 years	+5-10%
Anodizing	Qualanod Class 1	15-25μm	Natural/silver/bronze/black	20+ years	+8-15%
Fluorocarbon (PVDF)	AAMA 2605	≥30μm	Custom metallic	20+ years	+15-25%
Wood Grain Transfer	In-house standard	Sublimation on powder coat	6-8 wood patterns	10-15 years	+10-18%

Exterior Doors for Houses: Certification & Compliance Requirements

Certification Matrix by Target Market

Exporting exterior doors from China requires certifications matching the destination market’s building code. Below are the primary certifications and their testing parameters:

Certification	Market	Key Tests	U-Value Requirement	Test Lab Cost (USD)
CE (EN 14351-1)	EU/UK	Wind load, water, air, mechanical	Per national reg (1.0-1.8 W/m²K)	$3,000-5,000
NFRC	USA	Thermal transmittance (U-Factor), SHGC	≤0.30 (north), ≤0.35 (south)	$2,500-4,000
AAMA 2605	USA (coating)	Salt spray 4000hr, humidity 4000hr	N/A	$1,500-3,000
Miami-Dade NOA	Florida, USA	Large missile impact, cyclic wind	N/A	$8,000-15,000
AS 2047	Australia	Wind, water, air, NCC compliance	Per NCC 2022 (varies by zone)	$4,000-7,000
ISO 9001	Global (factory)	Quality management system	N/A	$2,000-4,000/yr

Factories with existing CE and NFRC certification reduce buyer cost by $5,000-10,000 per project. Verify current certificate validity and scope — some certificates cover only specific profile series.
