Long span cable trays mainly carry wires and cables, so it is necessary to do a series of anti-corrosion work. The following cable tray manufacturers will introduce how to carry out anti-corrosion for cable trays.

1、可以使用氯磺化底漆二道、面漆二道做為防腐橋架涂層結構。、

1. Two coats of chlorosulfonated primer and two coats of finish paint can be used as the coating structure of anti-corrosion bridge

2、金屬表面除銹質量的好壞，直接影響到大跨距電纜橋架的使用壽命，在現場除銹方法使用的是砂輪機除銹或者是進行人工除銹，除銹的級別需要達到ST3級別，在表面除銹之后，需要在4小時之內涂上底漆。如果發現出現新銹的時候，這就需要重新進行處理。

2. The quality of metal surface derusting directly affects the service life of long-span cable tray. The on-site derusting method is to use grinder derusting or manual derusting. The derusting level needs to reach ST3 level. After surface derusting, primer needs to be applied within 4 hours. If new rust is found, it needs to be treated again.

3、涂層的施工使用的是滾涂和刷涂，還需要符合，層間應縱橫交錯，單層往復進行涂平均為止不能夠漏涂。

3. The coating construction uses roller coating and brush coating, which also needs to meet the requirements. The layers shall be crisscross, and the single layer shall be painted back and forth, and there shall be no missed coating until the average.

在防腐施工時各種工序之間需要進行質量的檢查，在前道工序合格之后才可以進行下一道的工序施工，一道工序在完畢之后需要進行徹底的檢查，如果發現有缺陷，需要及時的修補，涂層的厚度以及涂裝的道數設計需要符合要求，要求表面平滑無痕，沒有針孔、流墜、粉化、破損等情況。

During anti-corrosion construction, quality inspection shall be carried out between various processes. The next process can be carried out only after the previous process is qualified. After the completion of the first process, it shall be thoroughly inspected. If defects are found, they shall be repaired in time. The thickness of the coating and the number of coating passes shall meet the requirements. The surface shall be smooth without marks, pinholes Sagging, pulverization, damage, etc.
