1250mm SGCC Blue RAL Prepainted Galvanized Steel Coil (PPGI) for Roofing Sheet with 20–275 g/m² Zinc Coating
1. Product Overview
PPGI steel coil combines a galvanized steel substrate with an organic coating system to provide both corrosion protection and decorative surface performance. It is widely used in roofing sheet production, where both durability and color consistency are required.
This specification focuses on widths up to 1250 mm and thickness from 0.12–1.20 mm, which matches mainstream roll forming and roofing panel manufacturing lines. Blue RAL color is commonly used in industrial buildings and prefabricated structures.
2. Technical Solution
The performance of this product is based on a dual-layer protection system:
Galvanized substrate with zinc coating 20–275 g/m²
Organic coating system (primer + top paint)
Top coating structure: 10–20 μm polyester + 5 μm primer
Back coating: 5–7 μm or 7–8 μm system
Surface treatment options including chromated, oiled, or anti-fingerprint
The zinc layer provides base corrosion resistance, while the paint system improves weather resistance, color retention, and surface stability.

8. FAQ
Q1: Is this PPGI or PPGL?
This specification follows galvanized substrate parameters (20–275 g/m²), so it is classified as PPGI.
Q2: What does 20–275 g/m² zinc coating mean?
It indicates the total zinc coating weight on both sides of the steel, affecting corrosion resistance.
Q3: Can this be used for roofing sheets?
Yes, it is specifically designed for roll forming into roofing and wall panels.
Q4: What is the coating structure of the paint system?
Top coating is polyester with primer, while the back side uses a thinner protective layer.
Q5: What is LFQ?
LFQ (Lock Forming Quality) ensures better forming performance during bending and roll forming.
