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.

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.
