Wrinkle Textured PPGI Coil
Embossed Matte Finish — Scratch-Resistant — Premium Aesthetic for Decorative Applications

Wrinkle textured PPGI coil features a specially formulated paint that creates an embossed, matte, wrinkle-finish surface during the curing process. Unlike standard smooth PPGI, the textured surface hides minor scratches, fingerprints and handling marks, making it ideal for applications where the product will be regularly touched or exposed to incidental contact.
The wrinkle finish is produced by controlling paint formulation, coating thickness and curing temperature to create a controlled surface texture. Typical wrinkle paint thickness is 25-35μm — heavier than standard smooth PE (15-20μm) — providing additional mechanical and weather protection.
Popular applications include garage doors, roller shutters, interior wall panels, decorative building facades, elevator interiors and premium consumer product housings where a high-end matte aesthetic is desired.
Technical Specifications
Available in various thicknesses, widths and coating options. Common standards include ASTM, JIS, EN and GB/T. Different industries may choose different specifications depending on service life, corrosion requirements and fabrication method.

PPGI vs PPGL
Both PPGI and PPGL are color coated steel products. The key difference is the substrate: PPGI uses galvanized (zinc) substrate while PPGL uses Galvalume (Al-Zn) substrate.
PPGI (GI Substrate)
Cost-effective color coated solution with broad market availability and wide application range.
PPGL (GL Substrate)
Premium color coated solution with 2-4× longer substrate corrosion life for demanding exterior use.
| Comparison Item | PPGI (GI Substrate) | PPGL (GL Substrate) |
|---|---|---|
| Substrate | GI (zinc coated) | GL (55% Al-Zn coated) |
| Corrosion Life | Good; standard outdoor performance | 2-4× longer than PPGI in same conditions |
| Cost | More economical | 5-10% higher |
| Best For | Interior, light exterior, appliances | Premium roofing, marine, harsh environments |
| Paint Adhesion | Excellent on zinc surface | Excellent on Al-Zn surface |
| Heat Resistance | Standard (GI substrate 230°C) | Higher (GL substrate 315°C) |
| Market Share | Higher volume, broader availability | Growing premium segment |

Quality Control and Inspection
Product quality is one of the key concerns for overseas buyers. Quality should be controlled not only by final visual inspection, but also by process stability, specification verification and export packing inspection.
Surface and Dimension Inspection
Surface condition, width, edge quality and dimensional tolerance are checked before delivery.
Pre-Shipment Quality Control
Packing condition, identification, quantity confirmation and shipment readiness are reviewed before export.
Thickness and Width Verification
Thickness tolerance, width and coil dimensions are checked to ensure the material is suitable for roll forming, profiling and project processing needs.
Coating and Surface Checking
Coating weight requirements and surface appearance are reviewed before packing and shipment.
Packing Inspection
Export packing is examined to ensure moisture-proof protection, steel straps and edge protectors are correctly applied.
Shipment Preparation
Quantity, identification, loading readiness and related documentation are confirmed before export delivery.
Standard Export Seaworthy Packaging
For steel export, correct packaging is extremely important. Even high-quality product can suffer surface damage, moisture exposure or edge deformation if packing is not suitable for sea shipment.
- Inner Moisture Protection: Waterproof kraft paper and plastic film help reduce moisture contact.
- Outer Steel Cover: Additional outer steel sheet gives stronger protection during handling.
- Edge Protection: Edge protectors reduce impact damage during lifting and stacking.
- Steel Strapping: Radial and circumferential straps help keep the coil stable.
- Pallet Support: Wooden or steel pallets can be used according to shipping requirements.
Shipping, Loading and Delivery Solutions
Shipping method depends on order quantity, coil size and destination requirements. Container shipment and break bulk vessel are the most common methods for steel coil export.
Container Shipment

Break Bulk Vessel Shipment
For large volume orders or oversized coils. Professional lifting, lashing and port handling for bulk steel procurement.
Small to medium orders: container shipment is preferred. Large-scale or project orders: break bulk vessel may be more efficient.
Frequently Asked Questions
What is PPGI?
PPGI (Prepainted Galvanized Iron) is galvanized steel coated with primer and paint on a continuous coil coating line (CCL). It provides color, aesthetics, and additional corrosion protection beyond the base zinc coating.
What paint systems are available?
PE (Polyester, 15-20μm, economy), SMP (Silicon Modified Polyester, 20-25μm, enhanced UV), HDP (High Durability Polyester, 20-25μm, premium), PVDF (Polyvinylidene Fluoride, 25μm, ultra-premium 20+ year exterior).
How to choose RAL color?
Provide RAL number (e.g. RAL 9003 Signal White), Pantone code, or physical sample. We color-match to ΔE ≤ 1.5 (visually identical). Popular: RAL 9002, 9003, 9006, 3009, 5015, 6005.
What is the difference between PPGI and PPGL?
PPGI uses GI (zinc) substrate; PPGL uses GL (Al-Zn) substrate. PPGL costs 5-10% more but lasts 30-50% longer. PPGL is preferred for premium exterior; PPGI is economical for interior and light-duty.
What is the MOQ?
25 MT per color/specification for full containers. Mixed containers: 5 MT/color minimum with 25 MT total.
Can wrinkle/textured finish be produced?
Yes. Wrinkle PE, embossed SMP and textured finishes are available for decorative applications. These finishes hide minor scratches and fingerprints.
