Project Description

PPGI is pre-painted galvanized steel, also known as pre-coated steel, color coated steel etc.

Using Hot Galvanized Steel Coil as the substrate, PPGI is made by first going through surface pretreatment, then the coating of one or more layers of liquid coating by roll coating, and finally baking and cooling. The coatings used including polyester, silicon modified polyester, high-durability, corrosion-resistance and formability.

We are a PPGI & PPGL manufacturer in Shandong, China. Our PPGI (Prepainted Galvanized Steel) & PPGL (Prepainted Galvalume Steel) are available in a variety of specifications.

We could also provide the product life length lasts for decades as customers required.
