PPGL Coil Overview

PPGL Coil Overview

What Is PPGL Coil

If you want a roof that lasts a long time, PPGL coil is a good pick. PPGL means pre-painted galvalume steel coil. To make it, workers put a special coating on cold-rolled steel. Then, they heat it up to make it strong. This makes the coil tough against rust and fading, even in strong sunlight.

PPGL coil is not only for roofs. You can use it for metal tiles, corrugated boards, skirting boards, and decorative panels. It is also good for lifts, door and window shutters, and shelves. PPGL coil works for both inside and outside projects.

Here’s why PPGL coil is important in building:

Definition of PPGL Coil

Primary Uses in Construction Industry

Pre-painted galvalume steel (PPGL) is made by putting a special coating on cold-rolled steel and heating it up.

Used to make metal tiles, corrugated boards, skirting boards, decorative panels, lifts, door and window shutters, and shelves for both inside and outside use.

PPGL coil is strong, saves money, and keeps out heat. It reflects heat, is easy to weld, and stays tough for many years. People trust PPGL coil for big buildings and homes.

Galvalume Steel Coil Composition

Galvalume steel coil is the main part of PPGL coil. It has a coating made from aluminum, zinc, and silicon. This mix helps stop rust and damage.

Component

Percentage

Role in Properties

Aluminum

55%

Stops rust from getting to the steel

Zinc

43.4%

Protects steel if it gets scratched

Silicon

1.6%

Makes the coating last longer

  • The coating has tiny areas with more aluminum and more zinc.

  • Aluminum-rich spots form first, then zinc-rich ones.

  • Silicon needles and a special layer help stop rust.

This galvalume steel stands up to water, heat, and wear. That is why PPGL coil is a smart pick for roofs, especially where weather changes a lot. If you look at PPGL and PPGI or other coils, PPGL lasts longer and is stronger.

Shandong Sino Steel Co.,Ltd sends galvalume steel coil and PPGL coil to over 200 countries. You can count on their full process and new products for your next roof or building job.


PPGL Coil Benefits for Roofing
