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、金属保护层：铁艺制品表面涂有一层不易生锈的金属或合金。常用的方法有电镀、喷涂、热浸镀等。但是用于铁艺制品的金属保护层一般应该是热浸镀锌的。由于在镀前经过的脱脂和除锈，在440的锌液中进行高温浸镀，镀层可以掩盖许多缺陷和缝隙，避免将来生锈，具有优异的附着性能。

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、非金属保护层：在铁艺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。

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、化学保护层：通过化学和电化学方法，如发黑、发蓝和磷化处理，在铁艺制品表面形成非金属保护层。

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：闸门的焊接部位很多，所以每个焊接部位的焊渣都一定要仔细。，用锉刀或扁铁敲打熔渣，然后用砂轮机和砂布打磨焊缝使其光滑。溅到其他部位的焊渣也应方便清理。

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、抛光原子灰：在干燥后，用研磨机和砂布全方面抛光闸门的所有部件，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、在喷油漆前，用湿布仔细擦拭大门所有部位，不留灰尘。先对其喷防锈漆，漆膜干燥后喷黑漆，然后喷清漆。注意不要遗漏喷涂部分，也不要流挂和其他缺陷。单个精细的部分可以用刷子。

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.

以上内容就是对铁艺大门的保护处理，大家在进行对其的保护处理时一定要遵循以上内容，是不是很精细复杂，每一扇大门都需要经过仔细的处理，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.
