ETP Coil Specification
-
The paint or resin coating applied over the galvanized steel substrate is measured in micrometers (µm) or grams per square meter (g/m²).
Typical coating thickness for PPGI ranges from 15 µm to 35 µm or higher, depending on environmental exposure and performance requirements. Higher coating thickness ensures improved durability, corrosion resistance, and long-term color retention.
-
PPGI coils are available with different paint systems based on project requirements, including:
Polyester (PE) – Cost-effective with good flexibility and surface finish
Silicon Modified Polyester (SMP) – Enhanced weather resistance
Polyvinylidene Fluoride (PVDF) – Superior durability, UV resistance, and long color life
Each paint system offers varying levels of weather protection, chemical resistance, and aesthetic performance.
-
PPGI coils are manufactured in various base steel thicknesses, typically ranging from 0.20 mm to 1.20 mm or more, depending on structural and application requirements.
Thickness selection depends on load-bearing capacity, fabrication needs, and end-use application.
-
PPGI coils are supplied in standard widths ranging from 600 mm to 1500 mm or above, subject to manufacturer capabilities and customer specifications.
Custom widths are available to suit roofing, cladding, and fabrication requirements.
PPGI Coil Trade Information
Pre-Painted Galvanized Steel
PPGI (Pre-Painted Galvanized Iron) is manufactured using galvanized steel coated with a protective zinc layer for corrosion resistance. The steel is pre-painted before fabrication, ensuring uniform surface quality and long-term durability.
Advanced Pre-Coating Process
The galvanized substrate undergoes a continuous coil coating process where primer and topcoat layers are applied on both sides. This ensures consistent thickness, strong adhesion, and enhanced resistance against moisture and environmental exposure.
Color Variety & Formability
Available in a wide range of colors, gloss levels, and finishes from matte to high-gloss. PPGI retains excellent formability, allowing easy shaping into roofing panels, cladding sheets, gutters, and structural components.
Wide Industrial Applications
Extensively used in roofing, siding, architectural panels, appliances, automotive components, and construction projects. PPGI combines structural strength, corrosion protection, and aesthetic flexibility for long-term performance.
