Product Introduction of PPGL Coil

Ppgl steel is a durable, colorful and economical building material. It is the abbreviation of pre coated galvanized steel. It takes aluminized zinc steel plate as the base material. Then, the aluminum zinc coated steel plate is continuously painted in the form of coils. Because of its excellent heat resistance and corrosion resistance, it has become the preferred material for a wide range of building applications, especially roof and wall. Wanzhi has exported its products to many countries around the world, such as Nigeria, Kenya, Turkey, Spain, Poland and so on. Please contact us for details!

Ppgl sheet and coil are widely used in many fields like ppgi steel, including
1. Construction industry, such as roof, wallboard, garage, ceiling, partition wall, etc.
2. Vehicle manufacturing industry, such as muffler, exhaust pipe, wiper accessories, fuel tank, truck box, etc.
3. Panel of household appliance industry, such as refrigerator, washing machine, air conditioner, electronic microwave oven, electrical cabinet, etc.
4. Agricultural uses, such as greenhouses, chicken houses, stables, hay houses, barns and greenhouses.

Advantages of PPGL Coil

1. Excellent corrosion resistance

Due to the 55% aluminum content, the corrosion resistance of ppgl is much better than that of ppgi, which can greatly prolong the service life.

2. Good thermal reflectance

Good heat resistance can keep buildings cool in hot summer.

3. Strong weather resistance

Pre coated galvanized steel sheet can resist severe weather conditions, such as extreme summer, winter or rainfall.

4. Good processability

Wanzhi Steel’s ppgl steel plate is easy to process, such as shearing, profiling, blanking, etc.

5. Beautiful appearance

They look attractive and impressive, with pleasant surface treatment and beauty.

Surface Coating Content

The coating composition of PPGI usually refers to the uniform zinc element.The coating composition of PPGL is usually 55% aluminum, 43.4% zinc, and 1.6% trace elements. Since the surface of the aluminum-zinc plate is an alloy plating layer, the chemical performance is much more stable than that of the base plate.


PPGI has a higher finish and looks more beautiful. PPGL steel coils have a higher finish than PPGI steel coils.


PPGL has higher corrosion resistance. If there are corrosion spots, the corrosion will spread on the PPGL board, but it will not spread on the PPGI board.


Because the performance of PPGL is higher than PPGI, the price of PPGL is higher than PPGI.

Need To Pay Attention To

When you need PPGL products, please try to use corrosion paint immediately after cutting to prevent the corrosion from spreading.
