The appearance of iron fence can cut and prevent the appearance corrosion of metal, and play a role in protecting the appearance and decoration of iron products in the process of decoration. As for iron products, the methods of appearance protection and finishing are generally used. There are many specific treatment methods, but in terms of iron guardrails, brush and electroplating (hot plating) are commonly used. If both are used, it is better for durability.

　　非金属防护涂层:在铁制品表面涂上一层或多层有机和无机化合物，如油漆、塑料、橡胶、沥青、搪瓷、耐酸材料、防锈油等。金属保护层:在铁制品表面涂上一层无腐蚀性的金属或合金，如锌、锡、镍、铬、铜、钛等。常用的方法有:电镀、喷涂、热浸镀锌等，但对于铁制品上的金属保护层一般应选用热浸镀锌。

　　Non metallic protective coating: apply one or more layers of organic and inorganic compounds on the surface of iron products, such as paint, plastic, rubber, asphalt, enamel, acid resistant material, antirust oil, etc. Metal protective layer: apply a layer of non corrosive metal or alloy on the surface of iron products, such as zinc, tin, nickel, chromium, copper, titanium, etc. Common methods include electroplating, spraying, hot-dip galvanizing, etc., but hot-dip galvanizing is generally used for the metal protective layer on iron products.

　　因为是镀前工件去除油锈和440摄氏度高温浸镀锌液体,所以它的涂层可以弥补很多不足和差距,防止将来生锈(特别适用于铁领域的产品生锈),具有优异的附着力和函数。化学保护层:在铸铁制品表面通过化学、电化学等手段，如黑、蓝、磷化处理等，形成非金属保护层。

　　Because it is a professional workpiece to remove oil rust and 440 ℃ high temperature dip galvanizing liquid before plating, its coating can make up for many shortcomings and gaps, prevent future rust (especially for products in the field of iron), and has excellent adhesion and function. Chemical protective layer: the non-metallic protective layer is formed on the surface of cast iron products by chemical and electrochemical means, such as black, blue, phosphating treatment, etc.

　　用上述几种方法获得自己的保护层既有保护作用，又有一定的装饰作用。但来讲济南铁艺护栏，广大用户不仅要求铁艺产品外观越来越要防锈，而且具有各种不同质感、立体感或者仿旧、仿古等艺术作用，或者外观富丽。在这个基础上。

　　The protective layer obtained by the above methods has both protective effect and decorative effect. But in terms of Jinan iron guardrail, the majority of users not only require the appearance of iron products to be more and more rustproof, but also have a variety of different texture, three-dimensional sense or imitation of the old, antique and other artistic functions, or the appearance of rich. On this basis.
