電纜橋架的材質有鍍鋅板、不銹鋼和鋁合金等，防火電纜橋架可以通過在鍍鋅電纜橋架基礎上噴涂防火塑粉來制作。橋架厚度標準定了橋架各個部件的厚度以及橋架表面防護層的厚度。更多詳細內容濟南橋架廠家為您講解：

The materials of cable tray include galvanized sheet, stainless steel and aluminum alloy, etc. The fireproof cable tray can be made by spraying fireproof plastic powder on the basis of galvanized cable tray. The thickness standard of the bridge determines the thickness of each component of the bridge and the thickness of the protective layer on the surface of the bridge. Jinan bridge manufacturer will explain more details to you:

1、防火電纜橋架

1. Fireproof cable tray

防火電纜橋架是為了保證起火后電纜能正常工作一段時間。防火電纜橋架敷設時，托盤梯架適合鋪設在易燃易爆氣體管道和熱力管道的下方。防火電纜橋架敷設時，托盤梯架適宜敷設在水管的上方，防止水管漏水后進水。

The fireproof cable bridge is to ensure that the cable can work normally for a period of time after the fire. When laying the fireproof cable tray, the tray ladder is suitable for laying under the flammable and explosive gas pipeline and heating pipeline. When laying the fireproof cable tray, the tray ladder is suitable to be laid above the water pipe to prevent water from entering after the water pipe leaks.

兩段防火電纜橋架的連接處或者活動連接板處，應該采用黃綠線或銅編織線進行兩端的連接，連接線的橫截面積不應該小于16平方毫米。防火電纜橋架在出入建筑物時，應與就近的總等電位接地裝置相連接。

The connection of two sections of fireproof cable tray or the movable connecting plate shall be connected at both ends with yellow-green wire or copper braided wire, and the cross-sectional area of the connecting wire shall not be less than 16mm2. The fireproof cable tray shall be connected with the nearby total equipotential grounding device when entering and leaving the building.

2、鍍鋅板

2. Galvanized sheet

鍍鋅板屬于橋架板材的一種，其他材質還有鋁合金、玻璃鋼、復合材料等。鍍鋅板表面有鋅層能夠防止橋架生銹，可以應用在各種環境的電纜橋架制作上。

Galvanized plate is one of the bridge plates, and other materials include aluminum alloy, glass fiber reinforced plastics, composite materials, etc. The zinc layer on the surface of the galvanized sheet can prevent the bridge from rusting and can be applied to the production of cable bridge in various environments.

3、鍍鋅工藝

3. Galvanizing process

電鍍鋅工藝做好需要有很好的電鍍溶液、適當的電鍍參數、調控參數裝備和技術高超的人員，否則很難獲得符合質量要求的鍍鋅層。熱浸鍍鋅能使整個鋼材基體表面都受到鋅層保護，無論是凹陷處管件內部，或者其他難以物理進入的角落，溶化的鋅都能很容易地均勻覆蓋上。

Good electroplating solution, proper electroplating parameters, control parameter equipment and skilled personnel are required for the electroplating process, otherwise it is difficult to obtain the zinc coating meeting the quality requirements. Hot-dip galvanizing can make the whole steel substrate surface protected by zinc layer, and the molten zinc can be easily and evenly covered on the inside of the pipe fittings at the depression or other corners that are difficult to physically enter.

4、橋架厚度

4. Bridge thickness

按照2013橋架標準，托盤、梯架的寬度大于800mm，如果為鋼制，橋架厚度應為2.2mm，如果為鋁合金，橋架厚度至少為2.5mm，如果為玻璃鋼制，橋架厚度小為5.0mm。橋架標準中噴塑工藝表面涂層的厚度要求>=50um,電鍍鋅表面鋅層厚度要求>=12um，熱浸鍍鋅表面鋅層厚度要求>=65um。VCI雙金屬涂層厚度要求>=60um。

According to the 2013 bridge standard, the width of the tray and ladder is greater than 800mm. If it is made of steel, the thickness of the tray should be 2.2mm. If it is made of aluminum alloy, the thickness of the tray should be at least 2.5mm. If it is made of glass fiber reinforced plastic, the thickness of the tray should be 5.0mm. In the bridge standard, the thickness of the surface coating of the plastic spraying process is required to be>=50um, the thickness of the zinc layer on the galvanized surface is required to be>=12um, and the thickness of the zinc layer on the hot-dip galvanized surface is required to be>=65um. VCI bimetallic coating thickness requirement>=60um.
