| 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.
- Building
- Roofing
- Transport
- Home Appliances, such as the side door plate of refrigerators,
shell of DVDs, air conditioners and washing machines.
- Solar Energy
- Furniture
| 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.

Differences between PPGI and PPGL
Definition and Application
The applications of PPGI Steel Coils are numerous, especially in
fabrication and manufacturing environments. Construction workers
mostly use Galvanized Coils for Roofing applications. They are also
used as sheet metal brakes in buildings.The biggest use of GI
Sheets is for construction projects in homes, offices, and
factories. They resist corrosion,heat, and are easily installable,
making them best suited for roofing. They are also used in the
production of corrugated panels, drywall panel profiles,
ventilation systems, etc.
