PPGI Coil

Description

1. Product Overview

The PPGI Coil is a high-performance, corrosion-resistant steel product manufactured by applying a premium organic coating to a zinc-coated galvanized iron substrate. It is primarily used in prefabricated building systems, roofing, cladding, and automotive components where long-term aesthetic durability is mission-critical. Offering an optimal balance of formability, weatherability, and lifecycle cost efficiency, PPGI Coil has become the strategic material of choice for industrial buyers seeking to reduce maintenance cycles while achieving consistent visual output across large-scale projects.

2. Key Specifications & Technical Characteristics

• Material Components: Hot-dipped galvanized steel substrate (DX51D, SGCC, or equivalent) + zinc coating (Z60–Z275 g/m²) + chemical conversion layer + primer + topcoat (polyester, PVDF, silicone-modified polyester, or epoxy)

• Purity / Grade Compliance: Conforms to ASTM A755 / A792, EN 10169, JIS G3312; coating hardness ≥ HB (pencil test), T-bend ≤ 3T

• Physical Characteristics:

  • Coil thickness: 0.12 mm – 1.5 mm

  • Coil width: 600 mm – 1,250 mm

  • Coating finish: Gloss (10–90 GU), matte, textured, wood grain, or metallic

  • Color range: RAL, Pantone, or custom digital match

• Packaging Options: Anti-rust paper + moisture-proof VCI film + galvanized steel pallets + reinforced edge protectors; seaworthy export packaging

• Shelf Life: 12 months under original packaging in dry, covered storage (≤50% RH, 5–35°C) without color degradation or corrosion

3. Core Industrial Applications

• Primary Industries: Construction (commercial & industrial roofing), HVAC, home appliances, automotive interiors, logistics infrastructure (warehouses, prefab shelters)

• Specific Operational Use Cases:

  • Roofing and wall cladding for factories and agricultural buildings

  • Roll-formed garage doors and window profiles

  • Electrical cabinets and white goods side panels

• Performance Advantage: Superior paint adhesion prevents delamination under bending or stamping; PVDF-coated variants resist UV fading for 20+ years, outperforming field-painted alternatives. Cost reduction comes from eliminating post-coating operations — cut, form, and install directly.

4. Competitive Advantages

• Quality Consistency: In-line coating thickness monitoring (accuracy ±2 µm) and salt spray testing (≥500 hrs for topcoat) ensure batch-to-batch uniformity certified by SGS/BV.

• Supply Reliability: Dual-source raw material agreements with Baosteel, POSCO, and ArcelorMittal; 98% on-time delivery rate over 36 months.

• Logistics Capability: Dedicated short-sea and container shipping routes from Tianjin, Shanghai, and Ho Chi Minh City ports to 60+ countries.

• Price Competitiveness: Direct mill allocation removes 2–3 intermediary layers; volume-driven pricing with quarterly index-linked adjustments.

• Sustainability: Chromium-free primer options available; fully recyclable substrate (EU WEEE and RoHS compliant); Scope 3 emission data available upon request.

• Technical Support: Full CAD library of recommended bending radii, fastener compatibility charts, and on-site coating repair protocols.

5. Commercial & Supply Information

• Minimum Order Quantity (MOQ): BULK 20MT per color / thickness combination

• Loading Capacity (per 20ft GP container): 22–24 MT (depending on coil inner diameter and packing method)

• Lead Time: 25 days after order confirmation and deposit (L/C at sight or T/T)

• Incoterms: FOB, CFR, CIF (major global ports)
