Colour Coated Steel Coil

Color coated steel coils are a type of steel coil that has a plastic or paint coating applied to its surface. This coating provides an aesthetically pleasing appearance and adds durability to the steel coil, making it more resistant to corrosion and other environmental factors.

What Is PPGI?

The full form of PPGI is pre-painted galvanized iron. It is also known as pre-coated steel, color coated steel, etc., which is an extension of GI. As the name implies, it uses zinc-coated steel as substrate, and then it is cleaned, pre-treated, applied with layers of coatings to make it more beautiful and durable to use. There are pre-painted Galvanized Steel coils and sheets on the market.

Prepainted steel sheet is coated with organic layer, which provides higher anti-corrosion property and a longer lifespan than that of galvanized steel sheets. The base metals for prepainted steel sheet consist of cold rolled, HDG electro-galvanized and Hop-dip zinc-alu-mag base metal. The finish coats of prepainted steel sheets can be classified into groups as follows: polyester, silicon modified polyesters, polyvinylidene fluoride, high-durability polyester, etc. 

Coating type:
There are 4 coating types could be applied on PPGI Cold Rolled Steel coils,it’s PE, SMP, HDP, PVDF.The following are the details for coating type introduction:

PE:

Commonly used,it’s short for Polyester polyester painting. It is mostly used in general environment,and anti-corrosion for 7-8 years, with strong adhesion.

SMP:

Silicone Mobified Polyester,which is resistant to contamination, weathering, self-cleaning, gloss retention, color retention, etc. It has low adhesion and is suitable for coastal areas.

HDP:

High weathering painting, high weather resistance, strong corrosion resistance, used in drying, temperature difference, and humidity. Such color steel plates are not recommended for coastal outdoor use.

PVDF:

Fluorocarbon paint, the most advanced and certainly the most expensive paint, the leader in paint. Strong anti-corrosion, long-lasting color, UV resistance.

Prepaind Galvanized Steel Coil applications

1. For construct building, light weight steel house, prefabricated house, container house, warehouse, factory, storage, workshop, office, etc.

2. For building materials, corrugated roof sheet, corrugated wall cladding, sandwich panel metal sheet, composite metal plate, etc
