Comparison of materials between galvanized sheet and aluminum alloy.

Galvanized sheet is a kind of composite material made of ordinary carbon structural steel, which is pretreated by pickling, cleaning and drying, and then covered with zinc layer by hot dip galvanizing process.

Aluminum alloy is an alloy material made of aluminum as the base material and processed by alloying process.

In terms of characteristics, galvanized sheet has good corrosion resistance and durability, and is suitable for complex environments; Aluminum alloy, on the other hand, has strength, hardness and wear resistance, and also has good corrosion resistance.

Aluminum alloy has low density but high strength, which is close to or higher than high-quality steel, and the strength of galvanized sheet is also high, which is suitable for structures with large load.
