What is Pre-painted Galvanized Iron and How to Use It?
What is Galvanized Iron?
Galvanised Iron (GI) is a metal alloy; either steel or iron, that has a layer of protective zinc coating applied to the surface to prevent rust. Prized for its protective steel properties in its zinc coated form, GI makes the perfect finished steel product for the industrial and construction industry. The most commonly used processing method, which we use here at Camasteel, is through hot-dip galvanizing.
Galvanized Iron (GI)
Pre-painted galvanized iron (PPGI) is another form of GI, formed in a similar process. The process is extended where it refers to factory pre-painted alternative to the zinc coated steel. The hot dip metallic coating process, where the iron is submerged in molten zinc is typically used to coat steel sheet and coil which may all be factory pre-painted like PPGI.

The differences between PPGI and PPGL can be analyzed with regards to substrates, durability, weight, appearance, features, applications and price:
PPGI uses a galvanized steel substrate as base metal. These galvanized sheets have a layer of zinc coating. However, PPGL uses galvalume cold-rolled steel sheets as a substrate. Galvalume sheets for PPGL are coated in 55% aluminum, 43.3% zinc, and 1.6% silicon.
PPGL sheets have a higher resistance against PPGI sheets, due to the dense layer of aluminum, which prevents the base metal from eroding.
The surface of a PPGL sheet is smoother than PPGI sheets. This is because aluminum is more adhesive than zinc.
PPGL is 3x more durable than PPGI; AI-ZN coating in PPGL is more resistant to corrosion, in comparison to the ZN-rich in PPGI.
Due to the lesser weight of aluminum when compared to Zinc, PPGLs AI-ZN coating is lighter than PPGIs zinc coating. Although, AI-ZN coating can occupy 3% more space than the GI sheet, even with the same weight.
PPGI and PPGL can be used for industrial and commercial purposes, including; automobiles, wall paneling, roofing etc. However PPGL is more suitable for adverse outdoor environments, due to its high corrosion resistant features.
PPGI sheets are 3%-11% lower in cost than PPGL sheets, due to varied, but minute reasons of process and material variance, durability and feature differences.
