Product Description

DC51D PPGL Cold Rolled Coil Color Coated Aluminum Zinc Iron Sheet Plate Coil

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.

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.
