Galvanized steel is a surface treatment technique for steel, which involves coating the steel surface with a layer of zinc to enhance its appearance and provide rust prevention. Galvanized steel is widely used in various fields such as construction, automotive, household appliances, electronics, and aerospace. It possesses excellent corrosion resistance and aesthetics, thereby improving the product's value and lifespan.
The galvanizing process of galvanized steel mainly includes two types: hot-dip galvanizing and electroplating galvanizing.
- Hot-dip galvanizing is a process in which steel is immersed in molten zinc to form a layer of zinc on the surface of the steel through a reaction.
- Electroplating zinc is a process that deposits zinc ions on the surface of steel through electrolysis to form a layer of zinc coating. Both processes can effectively protect the steel from corrosion, improve its aesthetics and prolong its service life.
Difference between hot-dip galvanizing and electroplating zinc:
- Process principle: Electroplating zinc is to plate a layer of zinc on the metal surface through electrode reaction. Hot-dip galvanizing is to immerse the metal material into molten zinc, so as to plate a layer of zinc on its surface.
- Appearance: The appearance of galvanized zinc is more beautiful, with a thinner coating. The appearance of hot-dip galvanizing is relatively less attractive compared to electroplated zinc, but the zinc layer has penetration, and the usage time is longer than electroplating.
- Galvanizing amount: The galvanizing amount of hot-dip galvanizing is usually large, with a minimum of 50-60g/m2 on both sides and a maximum of 600g/m2. The galvanizing layer of electroplated zinc can be very thin, with a minimum of 15g/m2.
- Corrosion resistance: Hot-dip galvanizing has good corrosion resistance because there is a slightly brittle compound layer between the pure zinc coating of the hot-dip galvanized sheet and the steel substrate, and the coating is uniform and free of pores. On the other hand, the zinc atoms of electroplated zinc only deposit and precipitate on the surface of the steel strip, which is prone to pitting corrosion caused by corrosive media.
- Application scope: Electroplating zinc is suitable for small-scale production with low output, and is applicable to products with high appearance requirements. Hot-dip galvanizing is suitable for large-scale production with high output, and is applicable to products with high corrosion resistance requirements.
Galvanized steel features
- Excellent corrosion resistance: The galvanized layer is thick, with fine and uniform crystallization and no pores, which can effectively protect the substrate material.
- Increase in strength: Galvanized steel has higher strength, prolonging its service life and durability.
- Malleability: Galvanized steel is suitable for manufacturing components of various machines, with good processing performance and plasticity.
Delivery terms
According to the delivery conditions of cold-rolled steel, the types of galvanized steel include steel coils and steel plates.
The translation of "镀锌钢价格" into English is "galvanized steel price".
The price of tin-plated steel is mainly determined by factors such as the weight of the steel coil, packaging method, transportation distance, and shipping method.
How to measure the weight of steel plates or steel coils?
The weight of steel plates or coils can be measured using the following methods:
- Weighing: The most direct method is to use weighing equipment, such as weighing platforms or weighing sensors, to place steel plates or steel coils on them for weighing. Ensure the accuracy and stability of the weighing equipment, and pay attention to fully leveling and fixing the steel plates or steel coils to avoid inaccurate weight measurement.
- Quantity Calculation: By measuring the dimensions (length, width, thickness) of steel plates or coils and using corresponding density or unit weight data, the weight can be estimated. This method is suitable for large quantities of steel plates or coils with similar specifications, and the weight can be obtained by calculating the average density and total volume.
