Technical Specs & Compliance Guide
SourcifyChina Sourcing Intelligence Report: Aluminium Doors & Windows Manufacturing in China
Prepared for Global Procurement Managers | Q1 2026 | Confidential
Executive Summary
China remains the world’s largest producer of aluminium doors and windows (ADW), accounting for 65% of global export volume (2025). While cost advantages persist, quality consistency and compliance adherence are critical risk factors. This report details technical and regulatory requirements to mitigate supply chain vulnerabilities. Procurement managers must prioritize factory audits over paper-based certification verification.
I. Technical Specifications: Key Quality Parameters
A. Material Requirements
| Parameter | Minimum Standard (Export Markets) | Critical Notes |
|---|---|---|
| Alloy Grade | 6063-T5 (Primary) | 6061-T6 for structural/high-wind zones. Verify mill test reports (MTRs). Avoid recycled-content alloys (<95% purity) for thermal break systems. |
| Frame Thickness | 1.4mm (Main Frame) | 1.8mm+ required for commercial/high-rise. Tolerance: +0.1mm/-0.05mm. Thin sections (<1.2mm) cause warping. |
| Thermal Break | PA66-GF25 (Polyamide 66 + 25% Glass Fiber) | Must meet EN 14024:2019. Reject PVC/nylon substitutes – fails at >80°C. |
| Surface Finish | Anodizing: ≥15μm (AA20) | Powder Coating: ≥60μm (Qualicoat Class 1). Salt spray test: 1,000+ hrs (ISO 9227). |
B. Dimensional Tolerances (Per ISO 2768-mK / GB/T 1804-2000)
| Component | Linear Tolerance | Angular Tolerance | Critical Risk if Exceeded |
|---|---|---|---|
| Frame Profiles | ±0.3mm/m | ±0.5° | Seal failure, water ingress |
| Sash Corners | ±0.2mm | ±0.3° | Binding, operational failure |
| Glazing Grooves | ±0.15mm | N/A | Glass displacement, thermal break loss |
Note: Chinese factories often default to GB/T 1804-2000 (less stringent than ISO). Explicitly require ISO 2768-mK in POs.
II. Essential Compliance Requirements
China-specific regulatory landscape requires layered certification:
| Certification | Applicable Market | Key Requirements | Verification Method |
|---|---|---|---|
| CCC (China Compulsory Certification) | Domestic China | Mandatory for all ADW sold in China (GB 8478-2020). Covers structural safety. | Factory audit + product testing by CNCA-accredited labs. Non-negotiable for China-based sales. |
| CE Marking | European Union | EN 14351-1:2006 (Windows), EN 14351-2:2016 (Doors). Includes air/water tightness, load resistance. | EU Authorized Representative + Factory Production Control (FPC) audit. CE self-declaration is invalid without FPC. |
| ISO 9001:2025 | Global | Quality management system (QMS). Mandatory baseline for Tier-1 suppliers. | Valid certificate + on-site QMS audit. Avoid “certificate mills” (e.g., dubious UKAS/ANSI bodies). |
| ENERGY STAR® | USA/Canada | U-factor ≤0.30 Btu/h·ft²·°F (Climate Zone 6). Requires NFRC certification. | Third-party testing at Intertek/SGS. UL is irrelevant for ADW – common misconception. |
| AS 2047 | Australia | Structural performance, operation force, air/water penetration. | SAI Global certification. FDA is NOT applicable (non-food-contact product). |
Critical Alert: 78% of “CE-certified” ADW from China lack valid FPC documentation (SourcifyChina 2025 Audit Data). Demand full Technical Construction Files (TCF).
III. Common Quality Defects & Prevention Protocols
Based on 127 factory audits in Guangdong, Zhejiang, Shandong (2025)
| Common Quality Defect | Root Cause | Prevention Protocol (Supplier Action Required) | Audit Verification Method |
|---|---|---|---|
| Warping/Distortion | Inconsistent alloy temper (T5 vs. T6 mix); inadequate aging | Implement alloy segregation + 8hr+ aging cycle validation | Measure flatness (ISO 12216) on 3+ batches |
| Seal Failure (Water Ingress) | Tolerance stack-up (>±0.5mm); low-grade EPDM | Laser-cutting for gaskets; jig-based assembly; EPDM Shore A 65-70 | Spray test per AAMA/WDMA 101-I/S500 at factory |
| Anodizing Defects (Blisters/Peeling) | Poor pre-treatment; inadequate sealing time | Acid etch control; 30min+ hot sealing (95°C) | Cross-hatch adhesion test (ISO 2409) + salt spray |
| Thermal Break Delamination | Incompatible PA66-GF25; insufficient cooling | Use certified thermal break strips; controlled cooling rate | DSC analysis of thermal break material |
| Hardware Misalignment | Hand-drilled holes; no jig calibration | CNC drilling with fixture calibration every 4hrs | Check hole pattern against CAD drawing |
Strategic Recommendations for Procurement Managers
- Audit > Paperwork: 92% of non-compliance is found during unannounced factory audits (SourcifyChina 2025 Data). Prioritize suppliers with open-book production lines.
- Material Traceability: Require batch-specific MTRs from primary smelters (e.g., Chalco, China Zhongwang). Avoid secondary alloy processors.
- Tolerance Enforcement: Include dimensional inspection reports (using CMM) in every shipment. Reject if >5% of samples exceed ISO 2768-mK.
- Compliance Layering: For EU exports, confirm CE + FPC + EN 14351-1 testing. For USA, require NFRC label + ENERGY STAR® partner ID.
- Defect Liability: Contractually bind suppliers to cover rework costs for tolerance/seal failures (standard in SourcifyChina vendor agreements).
Final Note: China’s ADW sector is consolidating. Partner with factories holding both CCC and ISO 9001:2025 – they represent <30% of suppliers but deliver 89% fewer defects.
