PPGI Coil Structure by HengZe Steel
HengZe’s Prepainted Galvanized Steel Coil (PPGI) is engineered with a multi-layered coating system that enhances corrosion resistance, paint durability, and overall product lifespan.
| Base Metal | High-quality galvanized steel with zinc coating (60–275g/m²) for strong rust protection. |
| Chemical Coating | Improves paint adhesion and adds extra corrosion resistance. |
| Primer Layer | Enhances bonding between substrate and topcoat, protects against moisture and chemicals. |
| Topcoat | Colored surface layer (PE, SMP, PVDF) for UV resistance, color retention, and surface durability. |
| Back Coating | Optional bottom layer for added protection and insulation compatibility. |

Frequently Asked Questions about PPGI
Yes, many of our prepainted galvanized steel coils are available with a removable protective plastic film (typically 30–80 μm) applied on the top-coated surface. This film helps protect the paint layer during fabrication, shipping, and installation, minimizing surface scratches or paint loss.
The Harmonized System (HS) code for PPGI coils is generally 721070 when the thickness is under 1.5 mm and width is over 600 mm. However, the exact classification can vary by country or application, so we recommend confirming with your local customs authority.
PPGI coil pricing depends on multiple variables, including:
Zinc coating weight (e.g., Z60–Z275 g/m²)
Paint system (Polyester, SMP, PVDF, etc.)
Color and surface finish (e.g., gloss, matte, woodgrain)
Paint thickness (top and back coating)
Coil dimensions and order quantity
For an accurate quotation, please provide detailed specifications and color preferences.
For general applications, HengZe PPGI coils use:
Top coat: 15–30 μm
Back coat: 5–15 μm
PVDF systems may require higher film thickness (up to 30 μm) to meet demanding weathering and UV resistance standards. Proper paint thickness ensures long-lasting color, gloss retention, and corrosion protection.
Service life depends on the coating system and environmental conditions:
PE (Polyester): 5–8 years
SMP (Silicon Modified Polyester): 10–15 years
PVDF (Polyvinylidene Fluoride): 15–25 years
In coastal, industrial, or highly humid regions, we recommend using PPGI with higher zinc coating weight and PVDF paint for enhanced corrosion resistance.
