Compared with other cable trays, the basement cable tray undoubtedly has its particularity, so the requirements for anti-corrosion are higher than other cable trays. The cable tray manufacturers will pay special attention to the role of anti-corrosion when producing this kind of cable tray, which results in its price much higher than other similar ones.

鑒于其使用環境更容易對電纜橋架鋁合金造成腐蝕，因此購買者在選擇哪一款橋架的時候更多的需要關注其防腐措施做的是否好這個問題，畢竟使用之后很快被環境腐蝕也就喪失了橋架的作用，更不要說長時間的使用橋架了。

In view of its use environment is more likely to cause corrosion to the aluminum alloy of cable tray, so buyers need to pay more attention to the problem of whether the anti-corrosion measures are good when choosing which type of cable tray. After all, it will lose the role of cable tray if it is corroded by the environment soon after use, let alone use the cable tray for a long time.

于對橋架如何防腐這個問題不同的廠家選擇的方式可能會有所不同，因此購買者在購買之前可以先對廠家進行詳細詢問，不過也不能忽略自己的使用地點，畢竟地點不同意味著環境不同，其造成腐蝕效果的因素也就會有所差別，在辨別防腐的時候也就需要區別對待。

As for the problem of bridge corrosion protection, different manufacturers may choose different ways. Therefore, the buyer can ask the manufacturer in detail before purchasing, but he can't ignore his own place of use. After all, different places mean different environments, and the factors causing corrosion effect will be different, When distinguishing anticorrosion, we need to treat it differently.
