PPGL Steel Coil

COSASTEEL is a China PPGL steel coil manufacturer.

PPGL Coil uses DX51D+AZ, 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 the PPGL steel coil, such as wood grain, or matt.

PPGL steel 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.

Please note that DX51D is only suitable for cold roll forming processing, if deep drawing processing, the PPGL steel sheet will break.

PPGL Coil Profile

PPGL Steel Coil 1

This is the PPGL steel coil Profile:

  • Top(Finish) Coating
  • Primer Coating
  • Chromate Coating
  • Zinc Coating
  • Base Metal(Cold Rolled Steel Sheet)
  • Zinc Coating
  • Chromate Coating
  • Epoxy, Polyester


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.

PPGL Coil Price in China

The main factors affecting the price of PPGL are the price fluctuations of steel raw materials, the thickness, and width of the substrate, the type of coating, the thickness of the coating, and the weight of the zinc layer.

What is the difference between PPGI and PPGL steel?

They are all based on cold-rolled steel sheets.

PPGI Coil is prepainted on cold-rolled steel sheets after galvanizing, and PPGL steel is prepainted on cold-rolled steel sheets with an alloy of 55% aluminum and 43.4% zinc.

The density of 55% AL-Zn is lower than that of Zn, and it is more cost-effective to use galvalume materials than galvanized materials.

Chinese PPGL Coil Manufacturer vs. Indian PPGL Coil Manufacturer

China’s hot-rolled steel coil production has accounted for more than half of the global hot-rolled steel output. In 2020, China’s hot-rolled steel output will actually account for 53.2%. In the same period, India’s hot-rolled steel coil production accounted for 5.6% of the world’s total output.

China’s PPGL steel coil production capacity is more, and the PPGL factories for cold forming are mainly concentrated in Boxing and Liaocheng. India needs to import PPGL steel materials, so the cost will rise

PPGL Stand For?

The full name of PPGL is pre-painted galvalume steel, also known as color coated steel. 

PP is short for pre-painted;

GL is short for galvalume;

What are PPGL steel coils used for?

PPGL Coil is cold-formed and processed into metal roofing by a roll forming machine, which is mostly used in civil buildings. PPGL with wood grain color can also be used for the exterior of the door.

There is also a Dx52D PPGL material that can be used for deep drawing processing, such as lamp housing.

How to Choose PPGL Coil?

When choosing PPGL steel coils, thickness, and color are usually considered.

You also need to pay attention to the mechanical properties of the substrate, such as yield strength.

The weight of the zinc coating of the galvanized steel sheet, the painting performance of PPGL (thickness, powder resistance, durability) and the type of painting, etc.
