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，山东电缆桥架的价格与钢制电缆桥架的价格之间存在显着差异。无论是批发还是零售，价格都有明显的差异。如果您想要更好的质量保证，则要不同角度出发。获得的价格优势将更加突出，因此如何确定材料的质量至关重要。

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.

山东电缆桥架的缺点是：

The disadvantages of Shandong cable tray are:

1.低电阻和低负载能力。由于技术限制，无法生产复合产品，因此它们的强度取决于产品内部的玻璃纤维纱，该纤维与其他两种材料相距甚远。它采用分体式结构，零件用螺栓或铆钉组装。搬运，在安装甚至使用期间，螺栓不可避免地会松动，从而降低桥的强度或损坏桥。

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.单向力。电缆桥架中只有纵向螺纹，而没有交叉螺纹。因此，产品的垂直强度相对较高，但是水平强度非常差，这仅由表面上的一层纤维毡提供。

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.耐腐蚀性不强，并且在腐蚀性环境中使用寿命受到限制。

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

通常，要确定山东电缆桥架材料的质量，您可以从山东电缆桥架获得相关信息。任何材料的桥架都要镀锌。这种表面处理过程可确保桥架具有更好的耐腐蚀性，耐湿性，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.
