PPGI Prepainted Galvanized Steel Coil

Product Overview

PPGI prepainted galvanized steel coil

PPGI is coated steel made on galvanized (GI) or galvalume (GL) substrate. After pretreatment, paint is applied and cured so the coil keeps corrosion resistance, weather resistance, color and formability in one product.

As a PPGI OEM manufacturer, Nicedeer supplies PPGI for construction, PPGI for home appliances, roofing PPGI coil, PPGI for corrugated sheet and PPGI for prefab house. Substrate options are AZ, GL and GI. Ask for the current PPGI export price and seaworthy packing.

Key Advantages

Why buyers specify Nicedeer PPGI

Coating plus metal substrate, with controlled PPGI coating thickness and PPGI corrosion resistance

Corrosion resistance

The organic film and metallic coating block moisture, oxygen and mild chemical attack. PPGI corrosion resistance is checked before shipment.

High weather resistance

High weather resistance PPGI uses SMP, HDP or PVDF systems so outdoor color holds up under UV.

RAL color chart

PPGI RAL color chart matching, including popular RAL 9006 / RAL 3005 PPGI, plus sample matching.

Formability

The film stays attached through shearing, bending, stamping and roll forming for corrugated sheet.

Made to tolerance

PPGI thickness tolerance, width, film build and PPGI coil weight 3–8 tons are set to the order.

Stable batches

Substrate, pretreatment, topcoat thickness, color difference and cure are controlled coil to coil.

Coating build-up

From the outside inward:

1. Topcoat: weather, color, scratch resistance

2. Primer: intercoat adhesion and corrosion hold

3. Conversion film: limits electrochemical attack

4. Zinc or Al-Zn: sacrificial protection

5. Steel base: structural strength

Coating Systems

SMP / PE / PVDF PPGI

Choose the paint by climate and the service life the roof or wall must deliver

Economy

PE polyester

Good adhesion, easy forming and a wide color range for mild outdoor exposure.

Service: about 7–10 years

Use: general workshops and temporary buildings

Harder film

SMP

Higher hardness and better gloss retention than standard PE, useful in sandy or abrasive sites.

Service: about 10–15 years

Use: dry regions, farm buildings, mining sites

Balanced

HDP

High weather resistance PPGI with durable resin and ceramic pigment for color hold.

Service: about 15–20 years

Use: strong UV, coastal parks, commercial buildings

Premium

PVDF

Strong UV, chemical and self-cleaning performance for severe coastal or industrial air.

Service: 20–25 years and beyond

Use: public buildings and harsh coastal sites
