PPGI is short for pre-painted galvanized steel, while PPGL is short for pre-painted galvalume steel. As the name suggests, PPGI uses galvanized sheets (with a layer of zinc coating) as base metal. While PPGL is with galvalume sheet as substrate, 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 influence their features and applications.
Prepainted galvalume steel coil is a kind of material, which can be processed into different products, such as roofing, panels, doors, etc. It is cost-effective, easy to transport and process, which is a great investment project.
For end-users, pre-painted galvalume steel sheets will be a better choice. PPGL sheets, including corrugated sheets, plain sheets, profile sheets, can be used directly as roofing, wall panels, etc. Or you can process the sheets into finished products, such as rolling doors, signal boards, etc.

Galvanized PPGL Steel Coil
Advantages of PPGL Steel
1. Excellent Corrosion Resistance
Due to the 55% of aluminum, the resistance to corrosion of PPGL is much better than PPGI's, which can greatly prolong the service life.
2. Great Heat Reflectivity
The good heat resistance can keep the buildings cool in the hot summer.
3. Weather Resistant
Pre-painted galvalume steel can withstand harsh weather conditions such as extreme summers, winters, or rainfall.
4. Good Processing Performance
The PPGL steel sheets from Wanzhi Steel are easy to profess, such as shearing, profiling, blanking, etc.
5. Beautiful Appearance
They look attractive and impressive with a pleasant surface finish and aesthetics.
PPGL Uses
PPGL sheets and coils are widely used in many areas just like PPGI steel, including
1. Construction, such as roofing, wall panels, garages, ceiling, partitioning walls, etc.
2. Vehicle manufacturing industry, such as mufflers, exhaust pipes, wiper attachments, fuel tanks, truck boxes, etc.
3. Home appliances, for example, the panels of the refrigerator, washing machine, air conditioners, electronic microwave ovens, electrical cabinets, etc.
4. Agricultural uses, such as greenhouses, chicken coops, stables, haylofts, barns, sheds.
