The advantages of galvanized steel mainly include the following aspects:
Strong corrosion resistance: The surface of galvanized steel is covered with a layer of zinc, which can effectively prevent oxidation and corrosion of steel in the atmosphere, and improve the service life of steel.
Good durability: Due to the protective effect of the zinc layer, galvanized steel can maintain its mechanical properties and appearance for a long time in harsh environments.
Good processing performance: Galvanized steel has good processing performance and can be cut, welded, bent, and processed like ordinary steel.
Enhancing Steel Strength: Galvanized coating can enhance the strength and stiffness of steel, and improve its load-bearing capacity.
Environmental protection: The galvanizing process does not produce harmful substances and meets environmental requirements.
However, galvanized steel also has some drawbacks:
High cost: The cost of galvanized coating is relatively high, resulting in a relatively high price for galvanized steel products.
Easy to scratch: The galvanized layer is prone to scratches and wear, which affects its corrosion resistance.
High requirements for welding: Due to the presence of a zinc layer, galvanized steel requires special process measures during welding to avoid welding defects.
Non recyclable and reusable: Galvanized steel cannot be recycled and reused after its service life, which increases resource consumption and environmental pollution.
In summary, galvanized steel has excellent corrosion resistance and processing performance, but the cost is high, and attention should be paid to protecting its surface from scratches.
