First of all, we must understand what is zinc flower, zinc flower is the steel plate in the hot dip coating surface in the solidification of the coating metal crystal pattern. After understanding what is zinc flower into the topic of this article, this article mainly discusses the formation of zinc flower, together to understand it.
1, water spraying: pure zinc solution on the surface of galvanized colored coated sheet does not solidify, caused by the nucleation of fine water mist (water and steam or a mixture of water and air). The unsolidified liquid zinc diffuses to form zinc flowers.
2. Surface blow molding method: when the pure zinc layer on the printed color galvanized sheet is about to solidify, if the zinc crystal can grow smoothly through the surface through the steam flow or the sulfur dioxide flow, the larger pattern can be obtained. The method can also form a dense oxide film and improve the corrosion resistance of the zinc coating.
3, screen method: this method is only applicable to galvanized sheet, used for steel wire mesh and zinc layer surface and magnetic roller contact, to achieve this purpose. Because the contact part of the steel mesh joint cools first, the solid particles in the junction form the crystal nucleus first. The crystal nucleus of the other unsolidified zinc liquid begins to expand outward, forming a zinc flower.
The production of zinc flower is related to the quality of finished products. Various factors should be taken into consideration when making large zinc flower on printed color coated cloth paper.
Galvanized corrugated steel sheet is made of galvanized steel. It is also known as corrugated GI sheet. It combines the strength of steel with the smooth surface of zinc coating. Due to its durability and beautiful appearance, it is widely used in many industry, especially roofing and wall panels. Compared to color coated steel sheet, GI corrugated steel sheet is more cost-effective. The available thickness is from 0.12 to 1.5 mm, and the width varies from 600 to 2,000 mm.

Read morePPGI steel coil combines long-service life with fashion appearance. Thanks to its good workability, PPGI coil can be further processed into plain or profile sheets for different uses. It is widely used in different industries, such as construction, automobile, furniture, home appliances, etc. Considering its wide applications, it is promising to invest in PPGI coils for business. Wanzhi Steel has its own factory and advanced production line to offers various colors and custom patterns of pre-painted galvanized steel coils to choose from. The thickness ranges 0.12-1.2 mm, and the width is from 600 to 1,250 mm. Welcome to contact us for more information!
Read moreGalvalume Steel Coil is a kind of Alloy-Coated Steel Sheet widely used in building materials, household appliances,automobiles, environment, machinery, ships and many other fields. The surface coating of galvalume steel sheet is composed of 55% aluminium, 43.5% zinc and a small amount of other elements. 1. Heat reflectivity: Aluminum-coated galvanized steel sheet has a high thermal reflectivity, which is twice as high as galvanized steel sheet. It is often used as insulation material. 2. Heat resistance: Aluminum-zinc alloy steel sheet has good heat resistance and can withstand high temperatures of more than 300 degrees Celsius. 3. Corrosion resistance: The corrosion resistance of aluminized and galvanized steel coils is mainly due to the protective function of aluminium and aluminium. When zinc is abraded, aluminium forms a dense layer of alumina,which prevents further corrosion of corrosion-resistant substances. 4. Economy: Because the density of 55% Al-Zn is smaller than that of Zn, the area of galvanized steel sheet is more than 3% larger than that of galvanized steel sheet under the same weight and thickness of gold plating. 5. Easy to paint: Aluminum-coated galvanized sheet and paint have excellent adhesion and can be painted without pretreatment and weathering treatment. 6. Aluminum-galvanized steel sheet has a silver-white gorgeous surface.
