The coating composition of galvalume corrugated roofing sheets is composed of 55% aluminum, 43.4% zinc, and 1.6% silicon, respectively by weight. The production process of galvalume sheet is similar to that of galvanized sheet and aluminized sheet, which is a continuous molten coating process. When exposed to the same environment on both sides of the 55% aluminum-zinc alloy coated aluminum-zinc sheet, it has better corrosion resistance than galvanized steel sheet of the same thickness. The 55% aluminum-zinc alloy coated aluminum-zinc steel sheet not only has good corrosion resistance, but also the color-coated products have excellent adhesion and flexibility.

Galvanized corrugated sheet is a profiled sheet made of galvanized sheets that are rolled and cold-bent into various wave shapes. It is a metal material, the surface is coated with zinc, which has good anti-rust, corrosion resistance, and durability. Widely used in construction, manufacturing, automobile, aviation and other fields.

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.

PPGI is a galvanized color-coated steel material. The coated steel sheet is subjected to surface chemical treatment, and then coating is applied and then baked. It has the mechanical strength and easy formability of steel plates, as well as the good decorative properties and corrosion resistance of organic materials. The coating has strong adhesion and can keep the color fresh for a long time. PPGI is widely used in various fields such as construction, home appliances, furniture, public facilities and transportation.
