Corrosion resistance: The surface of galvanized sheet is covered with a layer of zinc, which has good rust and corrosion resistance. In humid environment, galvanized sheet can resist corrosion and corrosion, and its service life is longer. Although aluminum plate also has good corrosion resistance, in some specific environments, such as sulfur-containing environment, its corrosion resistance may not be as good as galvanized plate.
2. Strength and hardness: galvanized sheet has high strength and hardness, which makes it show better performance under weight and pressure. In construction and manufacturing, galvanized sheet is often used for structural support, because it can bear a large load. In contrast, although aluminum plate is light, its performance may not be as good as galvanized plate in some occasions where high strength is needed.
3. Cost: galvanized sheet is more economical than aluminum sheet in cost. Although the price of aluminum is high, galvanized sheet is favored for its high cost performance in some large-scale production and construction projects. In addition, the processing and manufacturing process of galvanized sheet is relatively mature, which can meet all kinds of complex process requirements.
4. Applicability: Because of its corrosion resistance, strength and cost performance, galvanized sheet is widely used in various fields such as architecture, automobiles and household appliances. Aluminum plate is more used in occasions that require high light weight and beauty, such as aviation and automobile interior decoration. However, considering a variety of factors, galvanized sheet shows its superiority in a wider range of fields.
