热镀锌钢板及钢带（GI） |
1.产品介绍：
热镀锌钢板是为了防止钢板表面遭受腐蚀，以各种强度和厚度的规格冷轧基板为基材，在双面热镀一层金属锌，具有ZN的化学保护特性镀锌是指在金属、表面镀一层锌以起美观、防锈等作用的表面处理技术。主要采用的方法是热镀锌，它主要用于防止钢铁的腐蚀，其防护性能的优劣与镀层厚度关系甚大。锌镀层经钝化处理、染色或涂覆护光剂后，能显著提高其防护性和装饰性。
Hotdip galvanized steel plate is to prevent the surface of steel platefrom corrosion. It is based on cold-rolled substrate of variousstrength and thickness, and has a layer of metal zinc on bothsides, which has the chemical protection characteristics of Zn.Galvanizing refers to the surface treatment technology of plating alayer of zinc on the surface of metal and steel plate to play therole of beauty and rust prevention. The main method is hot dipgalvanizing, which is mainly used to prevent the corrosion ofsteel, and its protective performance is closely related to thecoating thickness. The protective and decorative properties of zinccoating can be significantly improved after passivation, dyeing orcoating with light protecting agent.
