High Strength PPGI Steel Coils with Zinc Coating Range from 30 to 275 Grams per Square Meter and Multiple Organic Coating Layers
ChromaSteel™ PPGI is a premium composite material that combines the strength of steel with superior corrosion resistance of zinc and the aesthetic versatility of high-grade organic coatings. Unlike traditional post-painting methods, PPGI is produced through a Continuous Coil Coating Process.
The process involves cleaning, pre-treating, and applying multiple layers of organic coatings (primer and finish paint) in a highly controlled factory environment. The result is a vibrant, uniform finish that offers significantly higher durability and weather resistance than spray-painted steel. ChromaSteel™ is the preferred choice for modern architecture and high-end appliance manufacturing where both form and function are non-negotiable.
Our PPGI is built upon a high-quality Hot-Dip Galvanized (GI) base to ensure that even if the paint layer is scratched, the underlying steel remains protected.
