Galvanized steel as an important anti-corrosion material, can be primarily categorized into plates, coils, pipes, strips, and profiles based on product form. Each type possesses distinct characteristics in terms of shape, performance, and application: galvanized steel plates feature smooth surfaces ideal for precision processing; steel coils suit automated production; steel pipes combine load-bearing with fluid transport functions; steel strips are used for precision components; while special-shaped materials meet professional requirements in power and construction sectors. This article will provide a professional analysis of the characteristics and applications of various products.

Galvanized steel plate: the most common galvanized product. They are produced by continuous hot-dip or electroplating processes. Its thickness usually varies from 0.3 to 6 mm. Its surface can be treated with chromate passivation to improve corrosion resistance. Due to its excellent flatness, it is particularly suitable for further spraying or color coating. This product is widely used in building roofs, household appliance housings, automotive parts and other fields. It is one of the basic materials for metal corrosion protection.

Galvanized steel coil: a roll supply form of galvanized products, usually with a width of 600 to 2000 mm and a thickness of 0.12 to 3 mm. Compared with flat products, steel coils have the advantages of high production efficiency and low transportation costs. It is suitable for continuous processing scenarios, such as making ventilation ducts, forming cable trays, etc. Users can choose different zinc layer weights according to their needs. Common specifications include Z60, Z180, Z275, etc.

Galvanized steel pipe: mainly processed by hot-dip galvanizing process, including two basic materials: welded steel pipe and seamless steel pipe. According to different uses, it can be divided into two categories: structural pipes and fluid conveying pipes. Its outer diameter ranges from 6 to 600 mm, and the wall thickness ranges from 0.5 to 20 mm. It has excellent corrosion resistance and is widely used in building scaffolding, municipal guardrails, water supply and drainage systems, etc. Products with special needs can be galvanized on both the inside and outside to further improve the protective performance.

Galvanized steel strip: It belongs to galvanized narrow strip products. Its width is usually less than 600 mm and the thickness is 0.1 - 3 mm. It is usually supplied in rolls. It is characterized by high dimensional accuracy and good surface quality. It is mainly used to produce products such as cable trays and shelves. It can also be directly used to manufacture light structural parts. Some high-end products use alloy galvanizing process to improve welding performance and weather resistance.

Other special galvanized profiles: such as structural materials such as angle steel, channel steel and H-shaped steel, as well as customized galvanized parts. This type of product is usually cast and then galvanized to provide long-term corrosion protection while maintaining structural strength. It is mainly used in high-voltage transmission towers, steel structure buildings and other occasions with high durability requirements.

Each type of galvanized steel product can be selected to have different zinc layer thickness and surface treatment methods according to the usage environment, such as plain zinc flakes, small zinc flakes, no zinc flakes and other surface forms, to meet the application requirements of different industries. When choosing in practice, factors such as anti-corrosion requirements, processing techniques and costs need to be comprehensively considered.
