Export of 3003 Alloy High-Gloss Aluminum Sheets for Canadian Construction Applications 1. Project Overview In September 2025, a 20-foot container of 3003 aluminum alloy sheets was exported from China to Canada, tailored for architectural applications including roofing systems and gutter downpipes. The shipment featured 0.96mm-thick sheets with double-sided high-gloss white coatings, meeting the stringent requirements of Canadian building codes and sustainable construction standards. This case details the product customization, compliance verification, and on-site application value of the project. 2. Product Specifications & Core Performance 2.1 Material & Dimensional Parameters The product was engineered based on 3003 aluminum alloy, a Al-Mn series material renowned for architectural durability. Key specifications are outlined below: Parameter Value Technical Significance Alloy Grade 3003 H16 Balances formability and corrosion resistance Thickness 0.96mm ± 0.02mm Optimal for structural load of roofing/gutters Coating Type Double-sided high-gloss white Modified acrylic resin (GB 18581-2001 compliant) Coating Glossiness ≥ 90 GU Enhances architectural aesthetics Density 2.72 g/cm³ Reduces structural weight by 65% vs steel Tensile Strength 145 MPa Exceeds Canadian CSA S136-19 minimum (120 MPa) 2.2 Coating Performance Advantages The high-gloss white coating adopted a roller-coating process to ensure uniform adhesion, achieving: Reflectivity of 92% to reduce roof surface temperature by 8-12°C Salt-spray resistance of 1,000 hours (ASTM B117), suitable for Canada’s coastal regions UV resistance rating of 4+, preventing fading under harsh winter sunlight   3. Compliance with Canadian Regulatory Standards 3.1 Mandatory Certifications & Documentation To access the Canadian market, the shipment completed two critical compliance procedures: Compliance Item Standard/Authority Verification Result Product Safety Certification CSA A409-18 (Aluminum Construction) Passed fire-resistance test per AS 1530.4 Origin Verification CCPIT-issued CO Certificate Valid for 12 months (Customs Entry No. CAN20250918) Coating Environmental Compliance REACH Regulation No restricted heavy metals detected 3.2 Construction Code Alignment The aluminum sheets met specific requirements for Canadian building scenarios: Roofing application: Conformed to NBCC 2020 (National Building Code of Canada) for wind uplift resistance (Class 4) Gutter downpipes: Complied with CSA B79-09 standards for water tightness and frost resistance 4. Application Adaptability Analysis 4.1 Performance Comparison with Traditional Materials In Canadian climatic conditions (temperature range: -35°C to 30°C), the 3003 alloy sheets outperformed conventional alternatives: Performance Metric 3003 Alloy Sheets (0.96mm) Galvanized Steel (1.2mm) Ordinary Aluminum (1050) Weight per m² 2.61 kg 9.42 kg 2.54 kg Service Life 25+ years 10-15 years 15-20 years Annual Maintenance Cost CAD 0.8/sq.m CAD 3.2/sq.m CAD 1.5/sq.m Corrosion Resistance No rusting Rusting after 3-5 years Pitting in coastal areas   4.2 Scene-Specific Customization Roofing: The 0.96mm thickness provided sufficient rigidity for snow load (up to 2.4 kPa) while enabling on-site bending for complex roof geometries. Gutter Downpipes: Double-sided coating prevented internal corrosion from rainwater and external damage from ice accumulation, reducing blockage risks by 40%. 5. Project Execution & Outcomes 5.1 Logistics & Clearance Timeline Phase Duration Key Deliverables Production & Testing 12 days CSA certification & coating performance report Documentation Preparation 3 days CO certificate, commercial invoice, packing list Ocean Shipping 18 days Departure from Shanghai Port to Vancouver Customs Clearance 1 day Duty rate 8% (applied under MFN status) 5.2 Client Feedback The Canadian contractor highlighted three core values: Material lightweight reduced installation labor by 30% compared to steel High-gloss finish enhanced building energy efficiency (estimated 12% reduction in HVAC costs) Compliance with local codes eliminated rework risks during inspections 6. Conclusion This export project demonstrates successful alignment of 3003 alloy material properties with Canadian architectural demands. The 0.96mm-thick, double-sided high-gloss aluminum sheets not only met mandatory certifications like CSA and REACH but also delivered tangible value in durability, sustainability, and cost-efficiency. As Canada accelerates green building initiatives, such customized aluminum solutions are poised to capture greater market share in roofing and plumbing applications.
