Anti-Corrosion Process & CE Certification BIPV Curtain Wall Steel Columns
Anti-Corrosion Process & CE Certification BIPV Curtain Wall Steel Columns from YTDR Group are tailored for global BIPV (Building-Integrated Photovoltaic) infrastructure projects. As a professional steel pipe manufacturer with rich overseas supply experience, we focus on solving corrosion and compliance pain points of B-end clients, providing high-performance, CE-certified steel columns that meet international market access requirements. Our products have been widely applied in 20+ countries across Europe, the Middle East, and North America, trusted by numerous engineering contractors and BIPV system integrators.
Core Quantitative Parameters (Focus on Anti-Corrosion & Compliance)
● Material: High-strength Q550 low-alloy steel (Yield strength ≥ 550MPa, Tensile strength 670-830MPa, Elongation ≥ 18%); optional Q355/Q420 materials for different load requirements
● Specifications: Outer diameter φ48mm - φ325mm, Wall thickness 3.0mm - 16.0mm, Length 6m - 12m (customizable); Pipe type: ERW welded / Seamless steel columns, Dimensional tolerance ≤ ±0.05mm
● Process: Precision hot-rolled forming + anti-corrosion treatment integration process; anti-corrosion process includes pre-degreasing → shot blasting (surface roughness Ra 40-70μm) → primer coating → finish coating, all processes comply with CE (EN 10219) standard requirements
● Standards: CE Certification (EN 10219), ISO 9001:2015 Quality Management System, GB/T 1591-2018, compatible with EU BIPV infrastructure design specifications
● Surface Treatment: Dual anti-corrosion system – Hot-dip galvanizing (zinc coating thickness ≥ 85μm, salt spray test ≥ 1000 hours) + optional 3PE/epoxy powder coating (coating thickness 2.5-3.7mm, salt spray test ≥ 2000 hours); surface adhesion ≥ 5MPa
l Anti-Corrosion Solution: Dual anti-corrosion process (hot-dip galvanizing + optional 3PE coating) passes 1000-hour neutral salt spray test (corrosion rate ≤ 0.01mm/year), solving the pain point of short service life of ordinary steel columns in coastal and high-humidity BIPV scenarios. Our products have a service life of ≥ 25 years, 60% longer than industry average single anti-corrosion products.
l Load-Bearing & Pressure Resistance: Q550 high-strength material ensures vertical load-bearing ≥ 15kN/m and horizontal wind load resistance ≥ 2.2kN/m², suitable for large-span BIPV curtain walls (span ≥ 10m). Passed third-party static load and fatigue tests, with test data traceable.
l Precision & Assembly Efficiency: Precision forming process ensures column ovality ≤ 0.5mm and straightness ≤ 2mm/m, matching perfectly with BIPV curtain wall connectors. Reduces on-site installation errors by 40% and shortens construction cycle by 20%.
ISO 9001:2015 integrated quality management system – strictly implemented from raw material procurement to finished product delivery (raw material inspection rate 100%, in-process inspection 3 times, final inspection 100%). Supporting certifications: CE (EN 10219, compliant with EU market access), SGS/BV third-party inspection reports (covering toughness, mechanical properties, coating quality), and CO (Certificate of Origin) for preferential tariffs. All certifications are traceable online via YTDR’s official platform, eliminating overseas clients’ concerns about quality compliance and market access barriers.
● High-Rise Commercial Building BIPV Curtain Walls: Applied in 100+ meter high-rises (e.g., office buildings, luxury hotels) in Europe, where high toughness and wind resistance are required. Our pipes have been supplied to 25+ such projects in Germany and France (e.g., Frankfurt Financial Center BIPV project), case studies available.
● Low-Temperature Region BIPV Projects: Suitable for BIPV curtain walls in Northern Europe (Sweden, Norway) and Northern America, resisting low-temperature brittle fracture. Cooperated with 20+ low-temperature region projects, case studies available.
● Public Infrastructure BIPV Projects (Earthquake-Prone Areas): Used in airport terminals, stadiums in the Middle East and Southeast Asia (earthquake-prone zones), where high toughness ensures structural safety. Supplied to 18+ public projects (e.g., Jakarta International Airport BIPV curtain wall), case studies available.
1. Supply Chain Capabilities
● Production Capacity: YTDR Group has an annual production capacity of 80,000 tons for BIPV special steel pipes; lead time for standard sizes is 7-15 days, and for customized sizes is 15-25 days (bulk orders can be negotiated for accelerated production).
● Logistics Support: FOB (Tianjin/Shanghai), CIF, and EXW terms are available; long-term cooperation with top shipping lines (Maersk, CMA CGM) to ensure on-time delivery (average sea transportation time to Europe 25-30 days, to North America 30-35 days); door-to-door delivery service is provided for key clients.
● Quality Inspection: 100% full inspection before shipment (including dimensional measurement, material testing, and coating inspection); third-party inspection (SGS/BV) at the buyer’s request is supported; 12-month quality warranty (free replacement for non-human damage caused by product quality).
2. After-Sales Support
● Technical Support: Professional technical team (with 10+ years of BIPV steel pipe design experience) provides free pipeline layout suggestions and load-bearing calculation services; 24/7 online after-sales service (supporting English, Spanish, and Arabic).
● Documentation Package: Complete and standardized export documents, including material certificate, SGS/BV test report, packing list, commercial invoice, CO certificate, and fumigation certificate (if applicable), ensuring smooth customs clearance.
