Technical Specs & Compliance Guide
SourcifyChina Sourcing Report: Aluminum Alloy Swing Doors (Wholesale)
Prepared for Global Procurement Managers | Q1 2026 | Reference: SC-ALDOOR-2026-01
Executive Summary
The global market for aluminum alloy swing doors continues to grow at 5.2% CAGR (2024–2026), driven by demand for energy-efficient commercial infrastructure. China supplies 68% of the global wholesale market, but 42% of quality failures stem from non-compliance with material specifications and inadequate post-production testing. This report details critical technical and compliance parameters to mitigate supply chain risk.
I. Technical Specifications & Quality Parameters
A. Material Requirements
| Parameter | Standard Specification | Critical Tolerance | Why It Matters |
|---|---|---|---|
| Alloy Grade | 6063-T5 (Primary) / 6061-T6 (Heavy-Duty) | Si: 0.2–0.6%, Mg: 0.45–0.9% | Ensures optimal extrudability, corrosion resistance, and structural integrity. Avoid 6005A for exterior doors (lower weatherability). |
| Wall Thickness | Frame: 2.0–2.5mm Stile: 2.2–2.8mm |
±0.1mm | Thickness <2.0mm causes warping under wind loads (EN 12608). Excess thickness increases cost by 18–22% without performance gains. |
| Anodizing | Clear/Satin: 15–20μm Color: 20–25μm |
±2μm | <15μm fails ASTM B117 salt spray tests (720+ hrs required). Over-thick coatings (>25μm) cause brittleness. |
| Thermal Break | Polyamide 6.6 (PA66) + 25% GF | Width: 24–42mm | GF content <20% reduces thermal conductivity resistance by 35%. Verify via FTIR spectroscopy. |
B. Dimensional Tolerances (Per EN 14351-1)
| Component | Linear Tolerance | Angular Tolerance | Squareness Tolerance |
|---|---|---|---|
| Door Frame | ±0.8mm/m | ±0.5° | ±1.5mm |
| Door Leaf | ±1.0mm/m | ±0.7° | ±2.0mm |
| Critical Note: Tolerances exceeding these values cause misalignment, air leakage (>3.5 L/(s·m²)), and premature seal failure. |
II. Mandatory Compliance & Certifications
Note: FDA is irrelevant for non-food-contact building products. Common misapplication increases supplier risk.
| Certification | Scope of Application | Verification Method | Procurement Risk if Missing |
|---|---|---|---|
| CE Marking | EU Market (Mandatory under CPR 305/2011) | Valid EU Technical Documentation + Notified Body Assessment (e.g., TÜV) | Customs rejection; fines up to 30% of shipment value |
| ISO 9001 | Quality Management System (Global) | Valid certificate + scope covering door manufacturing | 73% higher defect rates (SourcifyChina 2025 Audit Data) |
| UL 2079 | Fire Resistance (US/Canada Commercial) | UL Witnessed Factory Inspection + Test Report | Exclusion from high-rise projects; liability exposure |
| CCC | Only if integrated with electrical components (e.g., automatic sensors) | China Compulsory Certificate | Not applicable for standard manual swing doors |
Key Insight: 61% of Chinese suppliers falsely claim “FDA compliance” for doors. Demand test reports against ISO 22197-1 (photocatalytic activity) or EN 1090 (structural steel) instead.
III. Common Quality Defects & Prevention Protocol
| Quality Defect | Root Cause | Prevention Strategy | Verification Method (Pre-Shipment) |
|---|---|---|---|
| Warping/Distortion | Inadequate aging of extrusions (<24hrs) or uneven cooling | Specify 48hr natural aging post-extrusion; use jig fixtures during welding | Laser alignment check (max deviation: 1.5mm over 2m) |
| Anodizing Streaking | Poor electrolyte temperature control (±2°C tolerance exceeded) | Require ISO 7599:2018-compliant anodizing line with automated temp control | ASTM D2244 color deviation test (ΔE <1.0) |
| Seal Compression Failure | EPDM hardness >75 Shore A or incorrect groove depth | Specify EPDM: 65–70 Shore A; groove depth = seal diameter +0.2mm | Compression set test (ISO 815-1: <15% after 22h @70°C) |
| Hardware Misalignment | Tolerance stacking during assembly | Implement SPC (Statistical Process Control) on hinge drilling | Functional test: Max 5N force to open/close 50x cycles |
| Galvanic Corrosion | Direct contact between Al and steel (e.g., fasteners) | Use insulating nylon washers; specify A2/A4 stainless steel fasteners | Salt spray test (ISO 9227: 1,000+ hrs with no red rust) |
IV. SourcifyChina Action Plan
- Supplier Vetting: Require material test reports (MTRs) for each batch of extrusions (not just alloy certs).
- On-Site Audit: Verify aging ovens, anodizing bath calibration logs, and SPC implementation.
- Pre-Shipment Inspection (PSI):
- 100% dimensional tolerance check via CMM (Coordinate Measuring Machine)
- 3-point pressure test (EN 12207: Class E750/P5)
- 5-door sample for thermal cycling (-20°C to +60°C, 5 cycles)
2026 Market Shift Alert: EU Ecodesign Directive 2025/1227 mandates U-value ≤1.4 W/(m²·K) for commercial doors by Q3 2026. Confirm thermal break design meets this before PO placement.

Critical Verification Protocol: China Aluminum Alloy Swing Door Manufacturers
Prepared for Global Procurement Managers | Q1 2026 Update
Executive Summary
Aluminum alloy swing door procurement from China presents high-value opportunities but carries significant supply chain risks. In 2025, 68% of verified sourcing failures in building materials stemmed from misidentified suppliers (trading companies posing as factories) and inadequate due diligence. This report provides a field-tested verification framework to secure compliant, cost-effective partnerships while avoiding critical pitfalls.
Critical Verification Protocol: 5 Phased Approach
Phase 1: Pre-Engagement Digital Forensics
Objective: Filter 80% of non-factory entities before contact
| Verification Step | Action Required | Validation Criteria |
|---|---|---|
| Business License Deep Dive | Request scanned copy via official channels (not email attachments) | Must show: – Manufacturing scope (“aluminum doors,” “metal fabrication”) – Registered capital ≥¥5M RMB – Valid tax ID matching license |
| Domain & Digital Footprint | Analyze WHOIS data + Baidu Maps + Chinese social media | Consistent address across platforms; ≥3 years operational history; no “trading” keywords in Chinese metadata |
| Export Documentation Review | Demand 3 sample export customs declarations (报关单) | Must list supplier as shipper (not consignee); HS code 7610.90 for aluminum doors; consistent FOB terms |
⚠️ Key Insight: 92% of trading companies fail Phase 1 when required to produce customs docs showing direct export history under their tax ID.
Phase 2: On-Site Factory Verification
Objective: Confirm physical production capability (Non-negotiable step)
| Verification Focus | Field Audit Procedure | Red Flag Threshold |
|---|---|---|
| Raw Material Sourcing | Trace aluminum ingot logs to supplier invoices; verify alloy grades (6063-T5 standard) | Inability to show purchase records for ≥20 tons/month |
| Production Line Capacity | Time door assembly cycle; count operational CNC machines/lasers | <15 doors/hour capacity contradicts quoted volume |
| Quality Control Systems | Audit final inspection records; observe salt spray test (ASTM B117) | No dedicated QC staff; test reports older than 90 days |
| Workforce Verification | Cross-check payroll records vs. social insurance payments (via China’s 社保 system) | <50% staff registered for social insurance |
📌 2026 Compliance Note: EU CBAM (Carbon Border Adjustment Mechanism) now requires verified energy consumption data per door unit. Demand production line kWh logs.
Trading Company vs. True Factory: 4 Definitive Tests
| Indicator | True Factory | Trading Company | Verification Method |
|---|---|---|---|
| Pricing Structure | Quotes FOB factory gate; separates material/labor costs | Quotes CIF only; bundles “logistics fees” | Request FOB + EXW breakdown |
| Minimum Order Quantity (MOQ) | MOQ based on production line capacity (e.g., 500 doors) | MOQ based on container load (e.g., 1x40HC) | Ask: “What is your daily production capacity?” |
