型号差异对的影响

The impact of model differences on prices

　　槽式、托盘式、梯级式和网格式：

Slot, tray, step, and mesh formats:

　　槽式桥架：槽式桥架是全封闭结构，防护性能好，能有效防止灰尘、水分等对电缆的损害。由于其结构特点，在生产过程中需要更多的材料来制作侧板和盖板，而且对密封性能有一定要求，所以相对较高。在济南，相同规格的槽式桥架可能比梯级式桥架高15% - 20%。

Trough type cable tray: Trough type cable tray is a fully enclosed structure with good protective performance, which can effectively prevent damage to cables caused by dust, moisture, etc. Due to its structural characteristics, more materials are required in the production process to make side panels and cover plates, and there are certain requirements for sealing performance, so the price is relatively high. In Jinan, the price of trough type cable trays with the same specifications may be 15% -20% higher than that of stepped type cable trays.

　　托盘式桥架：托盘式桥架有较好的散热和透气性，其结构相对简单，材料使用量比槽式桥架少一些。但如果要达到较高的承载能力，可能需要增加板材厚度，会随之上升。一般情况下，它的介于槽式和梯级式之间。

Tray type bridge: Tray type bridge has good heat dissipation and breathability, and its structure is relatively simple, with less material usage than trough type bridge. But if you want to achieve a higher load-bearing capacity, you may need to increase the thickness of the board, and the price will rise accordingly. In general, its price is between slot style and cascade style.

　　梯级式桥架：梯级式桥架的结构较为开放，重量轻、成本低、便于安装和检修。其材料用量相对较少，在几种常见型号中通常是的。不过，对于一些特殊的应用场景，如需要承载较重的电缆，可能需要对其进行加固，这会增加成本，缩小与其他型号的差距。

Cascade bridge: The structure of the cascade bridge is relatively open, lightweight, low-cost, and easy to install and maintain. Its material usage is relatively small, and its price is usually the lowest among several common models. However, for some special application scenarios, such as carrying heavy cables, it may be necessary to reinforce them, which will increase costs and narrow the price gap with other models.

　　网格式桥架：网格式桥架通风性好、美观轻便，并且可以灵活调整电缆布局。它的制作工艺相对复杂，需要高精度的切割和焊接来保证网格的质量和整体的强度。在济南市场，网格式桥架通常比梯级式桥架高20% - 30%，因为其生产效率相对较低，而且材料成本（如采用不锈钢等材料制作网格）也较高。

Grid format cable tray: Grid format cable tray has good ventilation, is beautiful and lightweight, and can flexibly adjust cable layout. Its manufacturing process is relatively complex, requiring high-precision cutting and welding to ensure the quality of the mesh and overall strength. In the Jinan market, the price of grid style cable trays is usually 20% -30% higher than that of stepped cable trays, because their production efficiency is relatively low, and material costs (such as using high-quality materials such as stainless steel to make grids) are also higher.

　　材质型号（钢制、铝合金、不锈钢等）：

Material model (steel, aluminum alloy, stainless steel, etc.):

　　钢制桥架：钢制桥架相对较为亲民，是市场上较为常见的选择。但不同型号的钢制桥架也有差异。例如，热镀锌钢制桥架高于冷镀锌钢制桥架，因为热镀锌工艺成本高，但其防腐性能更好，使用寿命更长。在济南，热镀锌钢制桥架可能比冷镀锌钢制桥架高20% - 30%。

Steel bridge frame: Steel bridge frame is relatively affordable and is a common choice in the market. But the prices of different types of steel cable trays also vary. For example, hot-dip galvanized steel cable trays are more expensive than cold-dip galvanized steel cable trays because the hot-dip galvanizing process is costly, but it has better corrosion resistance and longer service life. In Jinan, the price of hot-dip galvanized steel cable trays may be 20% -30% higher than that of cold-dip galvanized steel cable trays.

　　铝合金桥架：铝合金桥架具有重量轻、耐腐蚀、美观等优点。不同合金成分的铝合金桥架不同，如6063 - T5铝合金桥架高于普通铝合金桥架。这是因为6063 - T5铝合金具有更好的力学性能和耐腐蚀性，其原材料成本和加工难度相对较高，可能会比普通铝合金桥架高出15% - 25%。

Aluminum alloy bridge: Aluminum alloy bridge has the advantages of light weight, corrosion resistance, and beauty. Aluminum alloy cable trays with different alloy compositions have different prices, for example, 6063-T5 aluminum alloy cable trays have higher prices than ordinary aluminum alloy cable trays. This is because 6063-T5 aluminum alloy has better mechanical properties and corrosion resistance, and its raw material cost and processing difficulty are relatively high. The price may be 15% -25% higher than that of ordinary aluminum alloy bridge frames.

　　不锈钢桥架：不锈钢桥架耐腐蚀性强，适用于恶劣环境。304不锈钢桥架高于201不锈钢桥架，因为304不锈钢含有更多的镍和铬元素，耐腐蚀性更好。在济南，304不锈钢桥架可能是201不锈钢桥架的1.3 - 1.5倍。

Stainless steel bridge: Stainless steel bridge has strong corrosion resistance and is suitable for harsh environments. The price of 304 stainless steel bridge is higher than that of 201 stainless steel bridge because 304 stainless steel contains more nickel and chromium elements, and has better corrosion resistance. In Jinan, the price of 304 stainless steel bridge may be 1.3-1.5 times that of 201 stainless steel bridge.
