The ST12 Galvanized Strip That Wins Customers-Jiangsu Sushang Steel

What is ST12 Galvanized Strip?

People who have some knowledge of stainless steel are generally familiar with Galvanized Strip. ST12 Galvanized Strip is a cold-rolled galvanized steel sheet with specific chemical composition and mechanical properties. , ST12 represents the grade of this steel sheet, where ST represents the purpose of the steel sheet (generally for structural use), and 12 represents its tensile strength grade. Galvanized, that is, galvanizing, is to immerse the steel sheet in molten zinc liquid to attach a layer of zinc to the surface of the steel sheet, thereby improving the corrosion resistance of the steel sheet. Therefore, ST12 Galvanized Strip not only has high strength and good processing performance, but also has excellent corrosion resistance, and is widely used in many fields such as construction, automobiles, and home appliances.

ST12 Galvanized Strip Production Process

The production process of ST12 galvanized steel strip is a complex and delicate process. Generally, the production process of ST12 galvanized steel strip can be divided into three main stages, as follows:

The first stage involves the preparation and pretreatment of raw materials. At this stage, first of all, high-quality steel that meets the ST12 standard needs to be selected as raw materials. These steels must undergo rigorous chemical composition and mechanical property tests to ensure that they meet production needs.

The second stage includes a series of pretreatment operations on the raw steel, which are as follows:

1) Hot-dip galvanizing: After pickling, it is cleaned by an ammonium chloride or zinc chloride aqueous solution or a mixed aqueous solution tank, and then sent to a hot-dip galvanizing tank for galvanizing.

2) Continuous galvanizing: After pickling, it is cleaned by an ammonium chloride or zinc chloride aqueous solution or a mixed aqueous solution tank, then sent to a continuous annealing furnace, and finally enters a galvanizing tank for galvanizing.

3) Direct galvanizing: After pickling, it is directly sent to a continuous annealing furnace and then enters a galvanizing tank for galvanizing. This stage is crucial to the quality of the final product because it is directly related to the adhesion and uniformity of the galvanized layer.

The third stage is relatively simple, mainly to coil the ST12 galvanized steel strip and store it in a warehouse. The weight of the galvanized layer is generally determined according to customer requirements, usually not less than 50 grams per square meter, and any sample shall not be less than 48 grams per square meter.

Uses of ST12 Galvanized Strip

1. ST12 Galvanized Strip is widely used in the automotive industry, mainly used to manufacture corrosion-resistant parts of cars. For example, the body, chassis, wheels and other parts of the car are often exposed to corrosive substances such as water, mud, and snow, so ST12 galvanized steel strips are needed to improve corrosion resistance and extend service life. In addition, ST12 galvanized steel strips also have good processing and welding properties, which can meet the diverse needs of the automotive industry for component shape and strength. Therefore, the application prospects of ST12 Galvanized Strip in the automotive industry are very broad.
Agriculture, animal husbandry and fishery are mainly used for grain storage and transportation, frozen processing tools for meat and aquatic products, etc.

2. ST12 galvanized steel is also often used to make cold storage, freezing equipment and various storage and transportation tools. Because grain is easily affected by factors such as moisture and pests during storage, grain storage equipment made of ST12 galvanized steel strips can effectively isolate the external environment and keep the grain dry and clean. At the same time, in the freezing process of meat and aquatic products, there are extremely high requirements for temperature control and sanitary conditions. ST12 galvanized steel strips can not only provide a stable low-temperature environment, but also effectively prevent bacteria from growing, ensuring the safety and quality of food.

3. ST12 galvanized steel strips are also often used in the field of home appliance manufacturing. Because of its good corrosion resistance and plasticity, it can not only provide a sturdy and durable shell, but also effectively resist scratches and impacts in daily use, extending the service life of home appliances. At the same time, civil chimneys made of ST12 galvanized steel strips can withstand high temperatures and corrosion, ensure smooth discharge of smoke, and protect the safety of the home environment. In addition, in the manufacture of kitchen utensils, ST12 galvanized steel strips also perform well. The pots and tableware made of it are not only beautiful in appearance, but also easy to clean, meeting the requirements of modern families for health and hygiene.
