Prepainted Galvanized Steel

Prepainted galvanized steel, commonly known as PPGI coil or painted GI steel, is a high-performance building material. It consists of a galvanized steel substrate coated with a durable layer of paint on one or both sides. This process combines the strength and corrosion resistance of galvanized steel with the aesthetic appeal and additional protection of a colored or patterned finish. As a leading prepainted steel manufacturer in China, ChinaCNU Steel produces premium PPGI for global construction and industrial projects, offering superior durability, color consistency, and design flexibility.

FAQ

Here are answers to some of the most common questions about our prepainted galvanized steel coils.

What is the difference between PPGI and regular galvanized steel?

PPGI (Prepainted Galvanized Steel) is galvanized steel that has undergone an additional coil coating process where layers of paint (primer and topcoat) are applied. This provides extra corrosion protection, UV resistance, and a wide range of colors, whereas regular GI steel has only the zinc coating for protection and a standard metallic appearance.

What paint systems and colors are available for your painted GI steel?

We offer standard Polyester (PE), Silicon Modified Polyester (SMP), and Polyvinylidene Fluoride (PVDF) paint systems. We provide a wide selection of standard RAL colors and can also develop custom colors to meet specific project requirements for architectural cladding or appliance manufacturing.

What is the typical lead time for a 40-foot container of prepainted steel?

For a standard 40-foot container order, the typical lead time from order confirmation to being ready for shipment FOB Qingdao is between 15 and 25 days, depending on the product specifications and our current production schedule.

Do you provide technical support for choosing the right PPGI coil specification?

Yes, absolutely. Our technical sales team can help you select the optimal steel grade, zinc coating, and paint system based on your application’s environmental conditions and performance requirements, such as for coastal area construction or industrial roofing.
