Differences between aluminum alloy and galvanized sheet in materials and properties.

There are significant differences between aluminum alloy and galvanized sheet in materials, properties and application scenarios. ‌

Material composition Aluminum alloy is a mixture of aluminum and other alloying elements (such as copper, silicon, magnesium, zinc, manganese, etc.), which has low density and high strength. Galvanized steel plate is based on ordinary carbon structural steel, which is formed by covering a layer of zinc on the surface of steel plate through hot dip galvanizing process. Performance characteristics Corrosion resistance: aluminum alloy will form a corrosion-resistant aluminum oxide film in air, which has good corrosion resistance and can be used for more than 20 years.

The anti-corrosion time of galvanized sheet is generally about 3 years, after which the anti-corrosion performance will be greatly reduced. Strength and weight: aluminum alloy has low density and light weight, but its strength is relatively low, and it is easy to be deformed and damaged. Galvanized square pipes have higher mechanical strength and can bear greater pressure and load.

Aesthetics: aluminum alloy can obtain rich colors and textures through various surface treatment processes, and the surface treatment layer is relatively more stable and not easy to fall off or change color. The surface of galvanized sheet is silvery gray, with poor aesthetics and easy peeling of zinc layer.
