Prepainted Aluzinc Steel Coil

Prepainted Galvalume Steel Coil

PPGL Coil uses DX51D+AZ, and q195 and galvalume steel sheet as the substrate, PE coating is our most commonly produced, it can be used for up to 10 years.

We can also customize the color of PPGL Coil, such as wood grain, matt.

PPGL sheet in coil is a kind of steel Coil with PE, HDP, PVDF, and other coatings. It has good processing and forming, good corrosion resistance, and the original strength characteristics of the steel plate.

Where is The Difference of PPGI and PPGL?

The primary difference between PPGI and PPGL is in the coating applied to each variant. PPGI or pre-painted galvanized iron steel is evenly covered with a layer of zinc. The zinc coating provides anodic protection to the base material, prolonging the product’s service life.

PPGL or pre-painted galvalume steel, on the other hand, is coated with a mix of aluminum, zinc and other trace elements. The usual composition of galvalume coating is 55% aluminum, 43.4% zinc and 1.6% trace elements.

Attributed to the difference in their coatings, PPGI and PPGL steel consequently vary in their properties as well.

1. PPGL steel offers a smoother finish than pre-painted galvanized steel.

2. Corrosion in PPGL steel spreads, whereas in PPGI steel it remains localized and do not spread easily.

3. PPGL steel is more corrosion resistant than PPGI steel, however, its cut edges are less protected. This is because of the steel coating’s honeycomb structure, which does not provide sufficient protection to exposed edges.

PPGL Coil 


The substrate is an annealed cold-rolled steel coil.

Chromated paint is used for cleaning the surface of the cold-rolled coil.

After Chromated, the next is zinc coated. The coil becomes a galvalume steel coil now.

After zinc coated, the next is Chromated again, for cleaning the galvalume steel coil surface again.

The primer coating is used for increasing the adhesion of the top coating. When cold roll forms, the paint will not fall off.

The top paint coating metal is PE or PVDF.
