Ppgi Corrugated Roof Sheet|Hot Dipped Galvanized Roofing Sheet
Continuous hot-dip galvanized corrugated steel sheet is abbreviated as galvanized sheet or white iron sheet. It is a cold-rolled continuous hot-dip galvanized sheet and steel strip with a thickness of 0.25~2.5mm. The steel strip is first passed through a flame-heated preheating furnace to burn off residual oil on the surface. At the same time, an iron oxide film is formed on the surface, and then it is heated to 710~920℃ in the reduction annealing furnace containing H2 and N2 mixed gas to reduce the iron oxide film to sponge iron. The surface activated and purified strip is cooled to slightly higher than the melting point. After the zinc temperature, enter the zinc pot at 450~460℃, and use the air knife to control the surface thickness of the zinc layer. Finally, passivation treatment with chromate solution to improve white rust resistance.
1. Improve corrosion resistance: The zinc coating on steel provides additional corrosion protection, extending the service life of the product.
2. Improve aesthetics: The bright, shiny finish of galvanized steel is more visually appealing than bare or painted steel.
3. Enhanced durability: The zinc coating increases the strength and stiffness of the steel, making it more resistant to damage and wear.
4. More sustainable: Galvanized steel is a recyclable material, so it can be reused or recycled at the end of its service life.
Lower maintenance costs: Because galvanized steel is more resistant to corrosion and wear, it requires less maintenance over time, reducing overall costs.
