With the booming development of the construction industry, project owners have various painting requirements, and the spread on the gi sheet has an impact on painting.
When selecting materials for zero spangle and regular spangle, the customer's specific usage must be clearly defined.
What is spangle?
Beautiful spangle is a characteristic of traditional hot-dip galvanized steel sheets. The most complete state of zinc crystals is more like snowflakes or six-pointed stars, so the zinc crystals condensed on the surface of the strip steel through hot-dip technology have a chance to form snowflakes or six-pointed star spangles.
In fact, spangle has ornamental value and has no actual practical use. On the contrary, the corrosion resistance of spangle is not good, and the surface will appear uneven after painting. Therefore, the home appliance and automobile manufacturing industries will choose small spangle (zero spangle) materials, and beautiful regular spangle products mostly appear in the construction industry.
Zero spangle gi sheet
Zero spangle gi sheet is widely used in construction, light industry, automobiles, home appliances, electronics, agriculture, animal husbandry, fishery, commodity packaging and other industries. In recent years, the demand for galvanized sheets in my country's construction, home appliance and other industries has grown rapidly, and the market potential is large. Especially in recent years, with the rapid development of lightweight construction structures, the increase in car production year by year, the widespread popularity of household appliances, joint ventures , The large-scale export of electronic products by wholly-owned enterprises has caused the consumption of galvanized sheets to grow rapidly.
Advanced production line configuration
Zero spangle gi products have a more uniform appearance than regular spangle galvanized products and are highly decorative. The surface without spangle edges is less likely to darken and is widely used in various major industrial fields.
Zero spangle products mainly refer to special production processes, which generally control the lead to a certain level in the zinc pot, or undergo special treatment after the strip comes out of the zinc pot, such as small spangle treatment or zinc powder spraying. To control the spangle to less than a certain level, you can get the Zero spangle product.
