The prices of Shandong cable trays made of different materials vary greatly, and the prices vary greatly due to different surface spraying processes. According to the wholesale price of hot-dip galvanized cable trays, it can be seen that the prices of trays of different materials are different. Therefore, it is very important to select cable tray suppliers, which is an important premise to ensure high cost.

例如，山東電纜橋架的與鋼制電纜橋架的之間存在顯著差異。無論是批發(fā)還是零售，都有明顯的差異。如果您想要更好的質(zhì)量保證，則要不同角度出發(fā)。獲得的優(yōu)勢將更加突出，因此如何確定材料的質(zhì)量關(guān)重要。

For example, there is a significant difference between the price of cable tray in Shandong and that of steel cable tray. Whether wholesale or retail, there are obvious differences in prices. If you want better quality assurance, you should start from a different angle. The price advantage will be more prominent, so how to determine the quality of materials is very important.

山東電纜橋架的缺點(diǎn)是：

The disadvantages of Shandong cable tray are:

1.低電阻和低負(fù)載能力。由于技術(shù)限制，無法生產(chǎn)復(fù)合產(chǎn)品，因此它們的強(qiáng)度取決于產(chǎn)品內(nèi)部的玻璃纖維紗，該纖維與其他兩種材料相距甚遠(yuǎn)。它采用分體式結(jié)構(gòu)，零件用螺栓或鉚釘組裝。搬運(yùn)，在安裝甚使用期間，螺栓不可避免地會松動，從而降低橋的強(qiáng)度或損壞橋。

1. Low resistance and low load capacity. Due to technical limitations, composite products cannot be produced, so their strength depends on the glass fiber yarn inside the product, which is far away from the other two materials. It adopts a split structure, and the parts are assembled with bolts or rivets. During transportation, installation and even use, the bolts will inevitably loosen, thus reducing the strength of the bridge or damaging the bridge.

2.單向力。電纜橋架中只有縱向螺紋，而沒有交叉螺紋。因此，產(chǎn)品的垂直強(qiáng)度相對較高，但是水平強(qiáng)度非常差，這僅由表面上的一層纖維氈提供。

2. Unidirectional force. There are only longitudinal threads and no cross threads in the cable tray. Therefore, the vertical strength of the product is relatively high, but the horizontal strength is very poor, which is only provided by a layer of fiber felt on the surface.

3.耐候性不高。

3. Poor weather resistance.

4.耐腐蝕性不強(qiáng)，并且在腐蝕性環(huán)境中使用壽命受到限制。

4. Poor corrosion resistance and limited service life in corrosive environment.

通常，要確定山東電纜橋架材料的質(zhì)量，您可以從山東電纜橋架獲得相關(guān)信息。任何材料的橋架都要鍍鋅。這種表面處理過程可確保橋架具有更好的耐腐蝕性，耐濕性，耐火性等。因此，有必要更多地了解提供者。

Generally, to determine the quality of Shandong cable tray materials, you can obtain relevant information from Shandong cable tray. The bridge of any material shall be galvanized. This surface treatment process can ensure that the bridge has better corrosion resistance, moisture resistance, fire resistance, etc. Therefore, it is necessary to know more about providers.
