What's the Pre-Painted Galvanized Iron (PPGI)?

Pre-Painted Galvanized Steel, also called PPGI. PPGI sheets coils are processed by coating with molten zinc. The zinc coating is a base metal that has protective properties making this type of sheet ideal and popular for roofing. PPGI steel is a beautiful and long-lasting material, which is widely applied in buildings, household appliances, furniture, and other areas. PPGI sheets are not easily corroded and so can withstand strong sun and rain.

Benefits of PPGI Sheet Coil

There are many benefits to purchasing pre-painted galvanized iron for your project, including:

  • Any shape can be created such as curved, rectangular, oval and tubular. Available in a variety of color ranges to choose from
  • Improve durability
  • Provide convenient cleaning facilities
  • affordable maintenance
  • Tensile properties provide sufficient strength to cover roofs, awnings and sheds.

According to the shape, we divide prepainted galvanized steel into coil and sheet. The thickness of our PPGI is from 0.12 mm to 1.2 mm. To make it easy to transport, PPGI sheets are often rolled up into coils. While for specific purposes, PPGI coils can be sheared and profiled into plain or corrugated steel sheets.

PPGI Sheet Coil Colors

The common colors include brick red, blue, green, grey, etc. Both glossy and matte colors are available. Also, there are different printed patterns to choose from, such as flower, grass, brick, wood grain, etc.

PPGI Sheet Coil Production Process

The process of manufacturing PPGI involves multiple steps. PPGI commonly uses a hot-dip zinc-coated steel (GI) as a substrate. Then the GI sheet in coil form is cleaned, pre-treated, and painted with layers of organic coatings, such as PE, SMP, HDP, PVDF, etc. The painting process is continuous, which is known as coil coating process. That's why PPGI steel consists of several layers, namely base metal, zinc coating, pre-treatment (chemical conversion coating), primer coating, and top/back coating. Below is a structure drawing for you.

After uncoiling, leveling and fixing, the pre-coated galvanized steel coil is cut into flat PPGI sheets of required length and width, and then processed into various styles of PPGI and PPGL top sheets by roller presses, such as corrugated steel sheets, corrugated sheets Tile, Roman long brick profiles, etc.

  • Steel furniture
  • White & brown Goods
  • Kitchen appliances such as Ovens, Ranges, Sinks, Kitchen Units, Shelves, Toilet Strands, and Cooker Wrapper

Differences Between PPGI And PPGL Sheets

  • Cost -- PPGI sheets cost less than PPGL sheets.
  • Various Base Metal -- PPGL is with galvalume sheet as substrate, which is coated with 55% aluminum, 43.3% zinc, and also 1.6% silicon. This is the main distinction between PPGI as well as PPGL.
  • Durability -- PPGI sheets are poorly compared to PPGL sheets when exposed to natural influences such as water. PPGL sheets may last beyond 10 years in good condition. They do not easily rust and do well. The lifespan of PPGL is almost double that of PPGI.
  • Thickness and weight -- Generally, PPGI sheets are lighter than PPGL sheets. The thickness however is dependent on the coating applied.
  • Finish -- PPGL sheets possess a smoother finish in comparison with PPGI sheets which can be directly caused by the aluminum component in PPGL which PPGI sheets do not have.
  • Corrosion resistance -- PPGL sheets are more corrosion resistant. When a PPGL sheet is cut, its edges become exposed which makes it more vulnerable to corrosion. PPGI is quite likely to become corroded.

PPGI Sheet Coil Price in 2022

In the first few months of 2022, the steel price in China kept increasing. Market demand is recovering. Influenced by COVID-19, some projects were delayed last year. But in 2022, most of them started again. When demand is exceeding supply, the price will go up.

The pre painted galvanized steel price changes every day. If you are looking for PPGI steel products, we advise you to place your order as soon as possible from a reliable supplier. Qinghe Steel is an industrial and trade company so that we can offer you a direct sale price. Welcome to contact us for today's price!


Which Countries Manufacture PPGI?

The main producers of Pre-Painted Galvanized Iron are China, Russia, Ukraine, India, South Korea, Vietnam.

How to transport PPGI Coil?

When storing the coil before transport, the steel’s lifespan will decrease if left in certain weather conditions. These may include rain or large temperature differences. The PPGI coil is wound during transport and will hold the water and create damage.

Labels are always checked and confirmed to make sure the correct product is shipped. The product is loaded and unloaded by forklift and transported to its destination or a ship for export. It is tied down and secured to prevent damage. View our Services>

As mentioned, PPGI uses galvanized steel as the base metal. But why PPGI coil price is similar to and even lower than galvanized steel coil price?

The galvanized steel coil price mainly depends on the zinc coating thickness. The thicker the zinc layer, the higher the price and the better the corrosion resistance. The galvanized steel used in PPGI has a thinner zinc coating. Also, the PPGI coil price will be different from the painting you choose, as well as the paint thickness. For example, the painted steel whiteboard price will be much higher than that of common PPGI steel. If you have special requirements, please let us know. We will offer custom solutions and a price list for you.

What is the PPGI coil HS code?

The HS code of PPGI steel coil is 7210 7010 00, which is described as flat-rolled products of iron or non-alloy steel, of a thickness less than 1.5mm, of a width of 600mm or more, plated, varnished, or coated with plastics. From May 1, 2021, the export tax rebate was canceled, which also influenced the price of the PPGI coil.
