電橋架是一種用于支撐和保護電纜的設備，由于其安裝過程中需要進行穿越建筑物的墻壁、樓板和隔墻等結構，因此會產生孔洞。為了保證建筑物的結構和防火性能，需要對這些孔洞進行封堵。電纜橋架孔洞封堵規(guī)范標準和  鋅橋架是一種常見的電氣設備支架，具有良好的耐腐蝕性能和機械強度。鍍鋅是指將鐵制品浸入熔化的鋅中，使其表面形成一層鋅層。鋅層能夠起到防止氧化和腐蝕的作用，從而延長橋架的使用壽命。

Electric bridge frame is a type of equipment used to support and protect cables. Due to its installation process, it needs to pass through the walls, floors, and partitions of buildings, resulting in holes. To ensure the structural safety and fire performance of buildings, it is necessary to seal these holes. Cable tray hole sealing standard and zinc tray are common electrical equipment supports with good corrosion resistance and mechanical strength. Galvanization refers to immersing iron products in molten zinc to form a layer of zinc on their surface. The zinc layer can prevent oxidation and corrosion, thereby extending the service life of the bridge.

鍍鋅橋架的鋅層厚度是一個重要的指標，它直接影響著橋架的耐腐蝕性能和機械強度。一般來說，鋅層厚度越大，橋架的耐腐蝕性能越好。根據行業(yè)標準和規(guī)范，鍍鋅橋架的鋅層厚度應符合以下要求：

The zinc layer thickness of galvanized cable tray is an important indicator, which directly affects the corrosion resistance and mechanical strength of the tray. Generally speaking, the thicker the zinc layer, the better the corrosion resistance of the bridge. According to industry standards and specifications, the zinc layer thickness of galvanized cable trays should meet the following requirements:

1、橋架表面應均勻、光滑，無氣孔、皺紋、刮痕等缺陷。

1. The surface of the bridge should be uniform, smooth, and free of defects such as pores, wrinkles, and scratches.

2、鋅層的平均厚度應符合標準規(guī)范要求，不能低于小厚度。

2. The average thickness of the zinc layer should meet the requirements of the standard specifications and cannot be lower than the minimum thickness.

3、鋅層應具有良好的附著力，不能出現剝離、脫落等現象。

3. The zinc layer should have good adhesion and should not exhibit peeling, peeling, or other phenomena.

根據標準和行業(yè)規(guī)范，鍍鋅橋架的鋅層厚度應滿足以下要求：

According to national standards and industry norms, the zinc layer thickness of galvanized cable trays should meet the following requirements:

1、一般橋架的鋅層厚度應不低于65μm。

1. The zinc layer thickness of general cable trays should not be less than 65 μ m.

2、橋架的焊接部位和切割邊緣的鋅層厚度應不低于50μm。

2. The zinc layer thickness of the welding parts and cutting edges of the bridge should not be less than 50 μ m.

3、橋架的內部和連接螺栓等部位的鋅層厚度應不低于40μm。

3. The thickness of the zinc layer inside the bridge and connecting bolts should not be less than 40 μ m.

4、深部彎曲處的鋅層厚度應不低于40μm。

4. The thickness of the zinc layer at the deep bend should not be less than 40 μ m.

需要注意的是，以上數據是根據常見的鍍鋅橋架的使用情況和要求得出的一般標準。對于特殊應用場景和要求更高的橋架，鋅層厚度可能會有所不同。因此，在選擇和使用鍍鋅橋架時，應根據具體情況和要求選擇合適的規(guī)格和型號。

It should be noted that the above data is based on the general standards derived from the usage and requirements of common galvanized cable trays. For special application scenarios and higher requirements of cable trays, the thickness of the zinc layer may vary. Therefore, when selecting and using galvanized cable trays, appropriate specifications and models should be selected based on specific circumstances and requirements.

總結起來，鍍鋅橋架的鋅層厚度是一個重要的標準規(guī)范，它直接影響著橋架的耐腐蝕性能和機械強度。根據標準和行業(yè)規(guī)范，一般橋架的鋅層厚度應不低于65μm，不同部位的鋅層厚度要求也有所不同。

In summary, the zinc layer thickness of galvanized cable trays is an important standard specification, which directly affects the corrosion resistance and mechanical strength of cable trays. According to national standards and industry norms, the zinc layer thickness of general cable trays should not be less than 65 μ m, and the zinc layer thickness requirements vary in different parts.
