PE Coated PPGI Prepainted Galvalume Steel Coil 0.2-0.6mm AZ100 For Indonesia Roofing Sheet Industry

Our PE Coated PPGI Prepainted Galvalume Steel Coil with AZ100 aluminum-zinc alloy coating is optimized for Indonesia's extensive roofing sheet manufacturing industry. Galvalume substrate (55% Al, 43.4% Zn, 1.6% Si) provides 3-6 times better corrosion resistance than conventional galvanized coatings, making it ideal for Indonesia's tropical climate with high rainfall, humidity, and coastal salt exposure. The AZ100 coating delivers superior cut-edge protection and long-term durability that Indonesia's competitive building materials market demands. The PE topcoat adds vibrant color options and additional UV protection while maintaining the cost competitiveness essential for Indonesia's price-sensitive residential and commercial roofing sectors.

Our PPGI coils are manufactured on continuous coil coating lines featuring advanced pretreatment, primer application, and precision top-coat curing systems. The multi-stage surface preparation process includes alkaline degreasing, hot water rinsing, and chromate-free chemical conversion coating to ensure exceptional paint adhesion and long-term corrosion resistance. Top-quality polyester, SMP, and PVDF paint systems are applied via reverse roll coating technology with closed-loop film thickness control, achieving uniform dry film thickness within ±2μm tolerance. Each coil undergoes comprehensive quality testing including color spectrophotometer verification against RAL/BS/Pantone standards, pencil hardness testing, T-bend flexibility assessment, reverse impact resistance evaluation, and salt spray corrosion testing per ASTM B117 for guaranteed performance in Indonesian tropical climatic conditions.

• Galvalume AZ100 Substrate: Aluminum-zinc alloy coating (55%Al-43.4%Zn-1.6%Si) at AZ100 (100 g/m²) provides 3-6x superior corrosion resistance versus conventional GI Z100, with excellent cut-edge sacrificial protection critical for profiled roofing sheets exposed to Indonesia's 2000mm+ annual rainfall.
• Tropical Climate Durability: PE coating system combined with Galvalume substrate tested to 1500+ hours salt spray resistance (ASTM B117) with less than 3mm scribe creep, ensuring structural integrity through Indonesia's monsoon seasons and coastal humidity.
• ACFTA Preferential Tariff (Form E): Certificate of Origin Form E under ASEAN-China Free Trade Area reduces import duties for Indonesian buyers, delivering landed cost savings of 5-8% versus non-preferential origin PPGI imports.
• Lightweight Gauge Options: Available from 0.20mm for cost-sensitive residential applications, enabling Indonesian roofing manufacturers to offer competitive end-product pricing while maintaining adequate structural performance with proper profile design.
• Jakarta & Surabaya Port Delivery: Regular container services to Tanjung Priok (Jakarta) and Tanjung Perak (Surabaya) ports with competitive ocean freight rates and 7-12 day transit times for responsive inventory management.

The consistent coating quality and precise dimensional control of our PPGI coils translate directly into manufacturing efficiency for downstream processors. Roll forming lines benefit from uniform strip profile and consistent friction characteristics, reducing tool wear and maintaining production speeds above 40 meters per minute for roofing profile production. The controlled coating thickness ensures complete substrate coverage even after deep profiling operations, eliminating touch-up requirements that slow production in competitive building materials markets. Our technical team provides complimentary color matching services using spectrophotometer analysis of customer-submitted samples, ensuring exact color reproduction within ΔE ≤1.0 for brand-consistent building projects. For large-scale developments, we offer coil-to-coil color consistency guarantees backed by batch-level quality certificates that document every production parameter from substrate zinc weight to topcoat peak metal temperature.

Every PPGI coil is protected with a polyethylene film masking layer over the painted surface, followed by waterproof kraft paper wrapping and heavy-duty steel strapping. Coils are mounted eye-to-sky on fumigated wooden pallets with full plastic shrink wrapping for maritime container transport. Inner diameter edge protectors prevent handling damage during loading and unloading operations. Each shipment includes detailed quality documentation: mill test certificates for the base steel substrate, coating weight certificates for the metallic coating layer, paint system datasheets listing primer type, topcoat chemistry, and DFT measurements, and RAL color comparison reports. We maintain ISO 9001:2015 and ISO 14001:2015 certified quality and environmental management systems. Third-party inspection by SGS, Bureau Veritas, or Intertek is available upon request. Our export documentation package includes Certificate of Origin, Form E/CO preferential certificates, fumigation certificates, and detailed packing lists ensuring smooth customs clearance in Indonesia and ASEAN and surrounding markets.
