We should all know that the iron gate is now the main use of Rural Courtyard and villa products, there are some like the door in the community you may have seen, it can not only effectively protect the safety of the home, but also has a beautiful appearance, relatively high-grade, how to protect the surface of the gate, through the following content to understand it.

1、金屬保護層：鐵藝制品表面涂有一層不易生銹的金屬或合金。常用的方法有電鍍、噴涂、熱浸鍍等。但是用于鐵藝制品的金屬保護層一般應該是熱浸鍍鋅的。由于在鍍前經過的脫脂和除銹，在440的鋅液中進行高溫浸鍍，鍍層可以掩蓋許多缺陷和縫隙，避免將來生銹，具有優異的附著性能。

1. Metal protective layer: the surface of iron products is coated with a layer of metal or alloy which is not easy to rust. The common methods are electroplating, spraying, hot dipping, etc. However, the metal protective layer for iron products should be hot-dip galvanized. Due to the professional degreasing and derusting before plating and the high temperature dip coating in 440 zinc bath, the coating can cover many defects and gaps, avoid future rust, and has excellent adhesion performance.

2、非金屬保護層：在鐵藝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。

2. Non metallic protective layer: coating one or more layers of organic and inorganic compounds on the surface of iron products, such as paint, plastic, rubber, asphalt, enamel, acid resistant materials, antirust oil, etc.

3、化學保護層：通過化學和電化學方法，如發黑、發藍和磷化處理，在鐵藝制品表面形成非金屬保護層。

3. Chemical protection layer: through chemical and electrochemical methods, such as blackening, bluing and phosphating, a non-metallic protective layer is formed on the surface of iron products.
                                                  

4、焊渣的清除：閘門的焊接部位很多，所以每個焊接部位的焊渣都一定要仔細清除。首先，用銼刀或扁鐵敲打熔渣，然后用砂輪機和砂布打磨焊縫使其光滑。濺到其他部位的焊渣也應方便清理。

4. Removal of welding slag: there are many welding parts of the gate, so the welding slag of each welding part must be carefully removed. First, the slag is knocked with a file or flat iron, and then the weld is ground smooth with a grinder and abrasive cloth. Welding slag splashed on other parts shall also be easy to clean.

5、拋光原子灰：在干燥后，用研磨機和砂布全方面拋光閘門的所有部件，尤其是涂有原子灰的部件。

5. Polishing putty: after drying, all parts of the gate, especially those coated with putty, are polished with a grinder and abrasive cloth.

6、在噴油漆前，用濕布仔細擦拭大門所有部位，不留灰塵。先對其噴防銹漆，漆膜干燥后噴黑漆，然后噴清漆。注意不要遺漏噴涂部分，也不要流掛和其他缺陷。單個精細的部分可以用刷子。

6. Before spraying the paint, wipe all parts of the gate carefully with a wet cloth to avoid dust. Spray antirust paint on it first, spray black paint after film drying, and then spray varnish. Be careful not to miss the spraying part, sagging and other defects. Individual fine parts can be brushed.

以上內容就是對鐵藝大門的保護處理，大家在進行對其的保護處理時一定要遵循以上內容，是不是很精細復雜，每一扇大門都需要經過仔細的處理，才可以更好的去使用它。

The above content is the protection of the iron gate processing, we must follow the above content in the protection of its processing, is not very delicate and complex, each door needs to be carefully processed, can better use it.
