Color Coated Prepainted Galvanized Steel Coil PPGL PPGI for construction
| What is Prepainted Aluminized zinc steel? |
Aluminized zinc sheet thick steel plate means that in order to avoid corrosion of the surface of the thick steel plate and increase its service life, the surface of the thick steel plate coat with a layer of metal zinc and aluminum. This kind of galvanized cold-rolled steel sheet is called galvalume.

Prepainted Galvalume Steel Coil/PPGL coating film introduction
Top paint film:
RPE, SMP, HDP,PVDF,Other paints.
Function: It functions as a sunlight proof cover, especially
prevent the destroy by the ultraviolet rays. When the top paint
film reaches a certain thickness, it forms a compact cover, and
reduce the water and oxygen permeability.
Primer paint film:
Polyurethane, Epoxy, PE
Function:Strengthen the adhesiveness between the top paint film and
the basemetal. Even permeable water happens, the top paint film
will not peel off. There is corrosion inhibitor which is corrosion
resistance. Polyurethane is necessary for higher processing
flexibility and weather resistance requirements.
Passivation layer
Function:Increase the adhesion between the metallic layer and
coating film. Extend life span also.
Metallic coating
Function:The metallic coating provides the fundamental protection
for the steel.
The popular coating metal are galvanize, galvalume and other
alloyed metals.
Substrate steel
Cold rolled steel is usually used as substrate, it decides the
mechanical properties and the steel shape and flatness.
Back paint film
Epoxy, Modified PE.
Back paint can sustain color in good condition and has good
binding.
| Prepainted Steel Applications |
PPGL have been extensively used across a wide range of prestigious projects across the world. Typical applications include construction, white goods and automotive industries.
| What is the difference between galvalume and galvanized steel? |
Galvanized steel is made completely of zinc, while galvalume includes aluminum, zinc, and a small amount of silicon. This provides superior durability and resistance to corrosion in comparison to galvanized coating.
