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.

　　非金屬防護涂層:在鐵制品表面涂上一層或多層有機和無機化合物，如油漆、塑料、橡膠、瀝青、搪瓷、耐酸材料、防銹油等。金屬保護層:在鐵制品表面涂上一層無腐蝕性的金屬或合金，如鋅、錫、鎳、鉻、銅、鈦等。常用的方法有:電鍍、噴涂、熱浸鍍鋅等，但對于鐵制品上的金屬保護層一般應選用熱浸鍍鋅。

　　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.

　　因為是鍍前工件去除油銹和440攝氏度高溫浸鍍鋅液體,所以它的涂層可以彌補很多不足和差距,防止將來生銹(特別適用于鐵領域的產品生銹),具有優異的附著力和函數。化學保護層:在鑄鐵制品表面通過化學、電化學等手段，如黑、藍、磷化處理等，形成非金屬保護層。

　　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.

　　用上述幾種方法獲得自己的保護層既有保護作用，又有一定的裝飾作用。但來講濟南鐵藝護欄，廣大用戶不僅要求鐵藝產品外觀越來越要防銹，而且具有各種不同質感、立體感或者仿舊、仿古等藝術作用，或者外觀富麗。在這個基礎上。

　　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.
