Difference Between PPGI and PPGL Tables
The difference between PPGI and PPGL sheets PPGI and PPGL sheets are two different color-coated steel sheets, which are widely used in various industries, such as advertising, construction, transportation, home appliance industry, etc., and they are very similar. But there are still some differences. So, what is the difference between PPGI and PPGL tables?
The difference between PPGI and PPGL sheets
1. Different substrates PPGI is the abbreviation of pre-painted galvanized steel, and PPGL is the abbreviation of pre-painted galvalume steel. As the name implies, PPGI uses galvanized sheet (with a zinc coating) as the parent material. PPGL is based on galvanized sheet, which is coated with 55% aluminum, 43.3% zinc and 1.6% silicon. This is the main difference between PPGI and PPGL, which will further affect their characteristics and applications.
2. Service life As mentioned earlier, both zinc coating and aluminum-zinc coating are used to protect metal from rusting to prolong its service life. For GI sheets, when the zinc layer is fully corroded, it will damage the base metal. Generally speaking, galvanized sheet can be used for 10 to 15 years. Alloys of aluminum and zinc form microscopic grain domains. Zinc-rich phases corrode preferentially, while aluminum-rich phases corrode very slowly. So Al-Zn coating is more corrosion resistant than galvanized steel. According to data, the service life of PPGL is three times that of PPGI.
3. Weight difference Under the same coating thickness, Al-Zn coating is lighter than zinc coating. This is because the specific gravity of aluminum is lower than that of zinc. That is to say, under the same weight, the Al-Zn coating can cover 3% more space than the GI sheet. Item Thickness (mm) Weight (g/m 2 ) GI 0.6 200 GL 0.6 350
4. Difference in Appearance The surface of PPGL sheet is smoother than that of PPGI sheet. This is because aluminum adheres better than zinc. For the same reason, PPGL sheets can be painted directly without pretreatment. However, for galvanized sheets, pretreatment is required.
5. Different characteristics The heat resistance of PPGL sheet is better than that of PPGI sheet. PPGL sheet can withstand the temperature of 315°C. In addition, PPGL sheets have better corrosion resistance than PPGI. This is because the dense layer made of aluminum prevents further corrosion of the base metal. GI and GL
6. Different Applications Both PPGI and PPGL sheets are widely used for wall panels and roofing. In contrast, PPGL has better corrosion resistance, which means it is more suitable for harsh outdoor environments. In addition, it is widely used in chimney pipes, ovens and lampshades, etc. due to its good heat resistance and good surface conductivity. But PPGL has less cut edge protection. Therefore, you can use anti-rust paint or zinc-rich paint on the cut edge. Cut edge protection geography, the cut edge of PP PPGL is less protected.

PPGI is an acronym for pre-painted galvanized iron while PPGL is an acronym for pre-painted galvalume steel. Also, analyzing the composition of both products is important in having a full grasp of the similarities and even more so the differences between PPGI and PPGL.

PPGI is a color coated steel, composed of galvanized sheets as a metal base, with zinc coating serving as a layer. This pre-painted steel has characteristics of high durability, and resistance against adverse weather and UV rays from sunlight. PPGI is also light weight, with usage cutting across various industries, such as construction, advertising and transportation.
Contact us to discuss your requirements of galvalume flat sheets. Our experienced sales team can help you identify the options that best suit your needs.
PPGL is also a color coated steel, but with galvalume sheet as substrate, coated with 55% aluminum, 43.3% zinc, and 1.6% silicon.
Both PPGI and PPGL have no doubts, similarities. However, analyzing the composition of both products is a step in the right direction to distinguishing the differences in these products.
PPGI can be used in manufacturing a wide range of products, such as refrigerators and freezer, washing machines, air conditioners, solar heaters, roofing, walling, LED TV, microwave ovens, furniture, containers, electrical cabinets, and door and window hoods, to mention but a few.
However, some of the most common forms of PPGI are PPGI sheets and PPGI coils.
The use of PPGI as roofing sheets can be seen as one of the most common uses of the material. PPGI is a widely sought-after material in the building and construction industries, the reason is not far-fetched, as PPGI sheets can easily be installed, reduces excess noise, have an impeccable thermal characteristic which ensures that the interiors of a building where it is used, are warm in winter and cold in summer.

PPGI steel coil is also used in building and construction specifically for roofing sheets, household appliances, and wall panels. It can also be used in automobiles. One distinctive feature of PPGI coils is the organic coating in various colors of the material, which enhances the appearance. In summary, exceptional strength and dimensional accuracy of PPGI coils makes it the best bet for roofing, fencing, lighting, ceiling accessories, interior cladding, steel furniture and kitchen appliances to mention but a few.

PPGL can be used in building and construction, as well as in the production of household appliances and agricultural equipment.
The PPGL sheet can be used in the lining for oil tanks, nuclear power plants, electricity boards, refineries and labs. Also PPGL sheets have remarkable anti-corrosive characteristics . The use of PPGL sheets cuts across a wide range of industries.

PPGL coils are widely used for making kitchen appliances such as ovens, ranges, shelves, sinks and kitchen units. Also, it can be used in the agricultural industry for the making of drying machines, silos, barns, farm equipment and greenhouses. The corrosion resistant coils are also commonly used in manufacturing products like bins, sign boards and vending machines.

The differences between PPGI and PPGL can be analyzed with regards to substrates, durability, weight, appearance, features, applications and price. Although PPGI and PPGL are both color coated steel, the usage of these products cut across various industries.
Difference between PPGI and PPGL SheetsDifference between PPGI and PPGL Sheets
1. Difference in Substrates of PPGI and PPGL
PPGI uses galvanized sheets as base metal. These galvanized sheets have a layer of zinc coating. However, PPGL uses galvalume sheets as substrate, just as the name implies. Galvalume sheets for PPGL are coated in 55% aluminum, 43.3% zinc, and 1.6% silicon .
From statistics, PPGL is 3 times more durable than PPGI, as the AI-ZN coating in PPGL is more resistant to corrosion, when compared to the ZN-rich in PPGI.
AI-ZN coating is lighter , compared to zinc coating. This is due to the lesser weight of aluminum when compared to zinc. Invariably, with the same weight, AI-ZN coating can occupy 3% more space than the GI sheet.
Generally, the surface of a PPGL sheet is smoother , when compared to the PPGI sheets. This is because aluminum is more adhesive than zinc.
PPGL sheets are more heat and corrosion resistant as opposed to PPGI sheets. This is due to the dense layer of aluminum, which prevents the base metal from eroding.
PPGI and PPGL sheets can both be used in wall paneling and roofing. However PPGL is more suitable for adverse outdoor environments, due to its high corrosion resistant features.
PPGL sheets are 3%-11% higher than PPGI sheets, this is as a result of its better performance , as previously explained.
