PPGI Steel Coil

Product Overview

PPGI steel coil — short for Pre-Painted Galvanized Iron coil — is a cold-rolled or hot-rolled galvanized steel substrate that has been cleaned, chemically treated, and coated with organic paint on one or both sides in a continuous coil-coating line. The result is a finished steel coil that combines the structural strength of the galvanized base with a durable, corrosion-resistant, and decorative color surface — ready for direct fabrication without secondary painting.

Product Advantages

This product offers a wide zinc coating range from Z30 to Z275 for flexible corrosion protection, a zero spangle surface for better paint consistency and appearance, compliance with GB, AISI, ASTM, and JIS standards for different export markets, and a broad thickness range from 0.11 mm to 2.50 mm to suit diverse fabrication needs. Backed by stable partnerships with major Chinese steel mills, it ensures reliable quality and supply, while OEM/ODM customization and in-house processing services provide buyers with more flexible specifications, easier sourcing, and higher overall purchasing efficiency.

Detailed Product Description

PPGI coils from Luyuan Metal are compatible with common downstream fabrication operations including:

Welding — for framing and structural connection
Punching — for ventilation, drainage, or decorative perforation
Cutting — shear-cut to length or slitting into narrower strips
Decoiling — direct feed into roll-forming or press lines
Bending — for panel edge profiling and corner forming

Applications

Roofing Sheets (PPGI Roofing Sheet)
Commonly used for roofing panels. Zero spangle surface is preferred for better visual uniformity.
Wall Cladding and Facade Panels
Suitable for exterior wall panels and facade systems. Color consistency is important, so RAL color confirmation is recommended before ordering.
Making Corrugated Sheets
Used for corrugated sheet production. Skin pass temper is recommended for smoother and cleaner forming.
Making Pipes and Tubes
Can be used for pipe and tube manufacturing. Hard temper is more suitable, and final dimensions should be confirmed with the supplier.
Fencing and Agricultural Structures
Ideal for outdoor fences and agricultural applications. Higher zinc coating is recommended for better long-term corrosion resistance.
