Product Description
The coating was aluminized zinc steel made of 55% aluminum, 43.3% zinc and 1.6% silicon. Aluminum forms a honeycomb layer around the zinc, which can protect the metal from further attack. This means that PPGL will be more durable. According to the data, the service life of PPGL roof panels under normal circumstances is more than 25 years. In addition, it is beautiful and generous, with various colors, patterns and patterns, which can meet different architectural styles. More importantly, PPGL steel has excellent heat resistance, which makes it an ideal roofing material even in hot climates. Whether it is home or investment, PPGL roof panels will be a good choice.
We provide many colors to choose from, the following are common colors, if you like other colors or patterns, please send us the RAL color code.

PPGL is short for pre-coated aluminum-zinc steel, which uses aluminum-zinc steel as the base material. It is widely used in many fields, especially in roof and wall systems.
High Corrosion Resistance
The coating was aluminized zinc steel made of 55% aluminum, 43.3% zinc and 1.6% silicon. Aluminum will form a honeycomb layer around the zinc, which can protect the metal from further attack. This means that PPGL will be more durable. According to the data, the service life of PPGL roof panels under normal circumstances is more than 25 years.
Excellent Heat Resistance
Galvanized zinc steel has good heat resistance and can withstand high temperatures above 300 degrees. In addition, it also has the characteristics of high thermal reflectivity. It can therefore even be used as an insulating material. This is why PPGL is a good choice for roofing materials.
Easy Installation And Maintenance
The weight of the PPGL sheet is much lighter than conventional materials. It can also be used directly. All you need to do is connect the roof slabs. As a roof, it is very easy to install to reduce construction time and cost. In addition, it is made of high-strength steel, which is enough to withstand extreme weather. No matter where you are, PPGL will be a cost-effective solution for your roof.
Beautiful Appearance
The aluminized zinc steel plate has good adhesion and smooth surface. Moreover, it can keep the color for a long time. Not only that, Wanzhi Steel also provides a variety of finishes and designs of PPGL corrugated board to choose from, which can adapt to different architectural styles. So no matter what color you want, glossy or matte, dark or light, please contact us for more details.
