The 380 tons of galvanized steel coils with zero spangle, which were purchased by the Lithuanian customer, have been shipped on July 31st, 2023. Lithuania is a stable overseas market for Wanzhi Group, and our galvanized steel coils have been well received by the Lithuanian market. The zero spangles galvanized coil purchased by the Lithuanian customer is the sixth time that the customer has purchased galvanized coils from Wanzhi. Through cooperation, we have established a deep friendship with the customer. Each time, we meet the contract delivery time. If you want to know more about Wanzhi Group, please feel free to contact us.
Zinc flower usually refers to the appearance of the grain formed after the hot-dip galvanized sheet is pulled out of the zinc pan and the zinc layer is cooled and solidified. The size, brightness, and surface morphology of zinc spangles depend on a series of factors but are mainly related to the composition of the zinc layer and the cooling method. The principle of producing zinc flowers is to try to reduce the solidification temperature of zinc liquid.
The galvanized steel coil has spangles and zero spangles are distinguished according to the surface state of the galvanized sheets, and the general weak eye will know that the surface has a pattern is a spangle, and there are zero spangles. Spangles and zero spangles have nothing to do with the material. The material depends on the substrate used for galvanizing, such as Q195, Q345, SPCC, and so on. There is also no relationship between thickness and the presence of zinc spangles. You can choose
|Zero Spangles Galvanized Coil
|Galvanized Coils with Spangles
|The composition of zinc liquid is zinc (99.5%), and aluminum (0.18-0.2%), which need finishing treatment;
|Zinc liquid contains zinc (99.5%) aluminum (0.18-0.2%), and antimony (0.05%).
|Scope of application
|Most of the surface needs to be painted, including home appliances, the automotive industry, color substrate
|It can be used as bare material, steel structure, barrel making, ventilation pipe, floor bearing plate, steel tile, gutter, and so on
Zinc spangles with a diameter greater than 3mm that can be distinguished by the naked eye are called large zinc spangles, and they are also called normal zinc spangles or natural zinc spangles. The internationally recognized best size is 8~12mm.
Zinc spangles with a diameter of 1~2mm are called small spangles. When the hot galvanized sheet comes out of the zinc pot, spray water mist or zinc powder to the zinc layer without solidification, then a water droplet, a zinc powder particle will form a crystallization center so that the number of zinc spangles per unit area increases and becomes smaller, so the galvanized surface will form small spangles that can be distinguished by the naked eye, traditionally the product produced by this process is called small spangles.
Zinc spangles cannot be seen with the naked eye on the surface of the board, which is called zero spangles, also known as zero zinc spangles, which are accomplished by controlling the chemical composition of zinc liquefaction. When hot dip galvanizing, only add a certain amount of aluminum to the zinc solution, without adding lead, antimony, or tin, you can produce zero-spangled products.
Galvanized coils are a widely used corrosion-resistant material. Many customers buy our galvanized coils for the production of corrugated sheets, construction, home appliances, and other industries. As a galvanized coil manufacturer, our factory has two galvanizing production lines, one of which has spangles galvanized line and the other has zero spangles galvanized line. Zinc layer 30-350g, two production lines annual output of 200,000 tons. Our output can meet the customer’s purchasing needs. Our factory uses fully automated production, the use of foreign imported quality testing equipment to ensure the quality of galvanized steel coils. The price of galvanized coils will be determined according to the width, thickness, and zinc layer thickness you need. Any questions, please free to contact us.
It is a pleasure to work with our Lithuanian customers once again. Our galvanized steel coils have become a star product in Lithuania. Many Lithuanian customers visit our factory and sign contracts directly to cooperate with us. In Wanzhi, galvanized coil has always been a hot product, and has been widely praised by customers. If you are interested in our galvanized steel coils, you can email me at any time, tell us the thickness, width, tons, zinc layer thickness, and other information you need, and we will arrange for the senior business manager to quote for you. You are welcome to visit the factory at any time.
