The production thickness of cable trays depends on specific design requirements and the materials used. Generally speaking, the production thickness of cable trays can be divided into the following common types:

1. 槽式電纜橋架：槽式電纜橋架是由一系列平面槽組成，通常有直角和T型兩種形狀。其生產厚度一般為2mm、2.5mm、3mm等。

1. Trough type cable tray: Trough type cable tray is composed of a series of flat grooves, usually in two shapes: right angle and T-shaped. The production thickness is generally 2mm, 2.5mm, 3mm, etc.

2. 梯級電纜橋架：梯級電纜橋架由一系列具有上平面和下平面的梯級組成。它們通常用于承載大量電纜和管道。其生產厚度一般為1.5mm、2mm、2.5mm等。

2. Step cable tray: Step cable tray consists of a series of steps with upper and lower planes. They are usually used to carry a large number of cables and pipelines. The production thickness is generally 1.5mm, 2mm, 2.5mm, etc.

3. 網式電纜橋架：網式電纜橋架主要由一系列排列交叉的鋼絲網格組成。其生產厚度一般為3mm、4mm、5mm等。

3. Mesh cable tray: The mesh cable tray is mainly composed of a series of arranged and crossed steel wire grids. The production thickness is generally 3mm, 4mm, 5mm, etc.

4. 鍛制電纜橋架：鍛制電纜橋架是通過加熱金屬材料使其軟化后，經由鍛造和冷卻再次變硬來制作的。其生產厚度一般根據具體需求定制。

4. Forged cable tray: Forged cable tray is made by heating metal materials to soften them, then hardening them again through forging and cooling. The production thickness is generally customized according to specific needs.

需要注意的是，以上僅列舉了一些常見的電纜橋架生產厚度，實際應用中可能還會存在其他規格。因此，在選擇和設計電纜橋架時，需要根據具體的工程要求和現場情況進行合理的選擇和設計。

It should be noted that the above only lists some common cable tray production thicknesses, and there may be other specifications in practical applications. Therefore, when selecting and designing cable trays, it is necessary to make reasonable choices and designs based on specific engineering requirements and on-site conditions.
