電纜橋架的材質選擇需根據敷設環境的特點進行匹配，以下是不同敷設環境對應的電纜橋架材質：

　　The material selection of cable trays should be matched according to the characteristics of the laying environment. The following are recommended cable tray materials for different laying environments:

　　1.普通室內環境

　　1. Ordinary indoor environment

　　· 鋼制橋架（鍍鋅或噴塑）：適用于一般室內干燥環境，強度高、承載能力強，相對較低，可通過鍍鋅或噴塑處理提高耐腐蝕性，滿足日常使用需求。

　　·Steel bridge frame (galvanized or sprayed): suitable for general indoor dry environments, with high strength, strong bearing capacity, relatively low price, and can be improved in corrosion resistance through galvanizing or spraying treatment to meet daily use needs.

　　· 鋁合金橋架：外觀美觀、重量輕，散熱性能好，適用于對美觀度要求較高或需要輕量化安裝的室內場所，如寫字樓、等。

　　·Aluminum alloy cable tray: It has a beautiful appearance, light weight, and good heat dissipation performance. It is suitable for indoor places that require high aesthetic requirements or lightweight installation, such as office buildings, shopping malls, etc.

　　2.潮濕或半潮濕環境

　　2. Wet or semi humid environment

　　· 熱鍍鋅鋼制橋架：表面鍍鋅層厚，抗腐蝕能力強，能有效抵御潮濕環境中的水分侵蝕，適用于地下室、隧道、潮濕的廠房等場所。

　　·Hot dip galvanized steel bridge: With a thick galvanized layer on the surface, it has strong corrosion resistance and can effectively resist moisture erosion in humid environments. It is suitable for places such as basements, tunnels, and damp factories.

　　· 不銹鋼橋架：耐腐蝕性極強，可在高濕度、高鹽霧等惡劣潮濕環境中長期使用，如沿海地區的建筑、化工廠的潮濕車間等。

　　·Stainless steel bridge frame: It has strong corrosion resistance and can be used for a long time in harsh and humid environments such as high humidity and high salt spray, such as buildings in coastal areas and wet workshops in chemical plants.

　　· 玻璃鋼橋架：具有良好的耐腐蝕性和絕緣性能，適用于潮濕且可能有化學腐蝕的環境，如污水處理廠、造紙廠等。

　　·Fiberglass bridge frame: It has good corrosion resistance and insulation performance, and is suitable for humid and potentially chemically corrosive environments, such as sewage treatment plants, paper mills, etc.

　　3.強腐蝕性環境

　　3. Strong corrosive environment

　　· 不銹鋼橋架（316L材質）：適用于強酸、強堿、強鹽等極端腐蝕性環境，如化工生產裝置區、電鍍車間、海洋工程等，其耐腐蝕性能遠超普通材質橋架。

　　·Stainless steel bridge frame (316L material): suitable for extremely corrosive environments such as strong acid, strong alkali, strong salt, etc., such as chemical production equipment areas, electroplating workshops, marine engineering, etc. Its corrosion resistance performance far exceeds that of ordinary material bridge frames.

　　· 玻璃鋼橋架：對酸、堿、鹽等腐蝕性介質有較好的抵抗能力，尤其適用于含有腐蝕性氣體或液體的場所，如化工儲罐區、酸洗車間等。

　　·Fiberglass bridge frame: It has good resistance to corrosive media such as acid, alkali, salt, etc., especially suitable for places containing corrosive gases or liquids, such as chemical storage tank areas, acid pickling workshops, etc.

　　4.防火要求較高的環境

　　4. Environments with high fire prevention requirements

　　· 防火橋架：通常由金屬骨架與防火板復合而成，表面涂覆防火涂料，具有良好的耐火性能，適用于電纜密集、防火要求嚴格的場所，如數據中心、醫院、等人員密集的公共建筑。

　　·Fireproof bridge: usually composed of a metal skeleton and fireproof board composite, coated with fireproof coating on the surface, with good fire resistance performance, suitable for places with dense cables and strict fire protection requirements, such as data centers, hospitals, shopping malls and other densely populated public buildings.

　　· 鋼制橋架（加防火涂料）：在普通鋼制橋架表面涂刷防火涂料，可提高其耐火性能，滿足一定的防火要求，適用于對防火有一定要求的工業和民用建筑。

　　·Steel bridge frame (with fireproof coating): Applying fireproof coating on the surface of ordinary steel bridge frame can improve its fire resistance performance, meet certain fire prevention requirements, and is suitable for industrial and civil buildings with certain fire prevention requirements.

　　5.電磁屏蔽要求較高的環境

　　5. Environments with high requirements for electromagnetic shielding

　　· 槽式鋼制橋架（帶蓋）：全封閉結構可有效屏蔽電磁干擾，適用于計算機房、通信機房、廣播電視發射塔等對電磁干擾敏感的場所。

　　·Trough type steel bridge frame (with cover): The fully enclosed structure can effectively shield electromagnetic interference and is suitable for places sensitive to electromagnetic interference such as computer rooms, communication rooms, broadcasting and television transmission towers, etc.

　　· 不銹鋼橋架：具有良好的電磁屏蔽性能，同時兼具耐腐蝕性，適用于對電磁屏蔽和耐腐蝕性都有要求的環境，如電子芯片制造車間、航空航天設備測試場所等。

　　·Stainless steel bridge frame: It has good electromagnetic shielding performance and corrosion resistance, and is suitable for environments that require both electromagnetic shielding and corrosion resistance, such as electronic chip manufacturing workshops, aerospace equipment testing sites, etc.

　　6.戶外環境

　　6. Outdoor environment

　　· 熱鍍鋅鋼制橋架：抗腐蝕性強，能承受戶外的風吹日曬雨淋，適用于戶外電纜架空敷設或沿建筑物外墻敷設的場景。

　　·Hot dip galvanized steel bridge: Strong corrosion resistance, able to withstand outdoor wind, sun, and rain, suitable for outdoor cable overhead laying or laying along building exterior walls.

　　· 鋁合金橋架：重量輕、耐腐蝕，且具有較好的耐候性，適用于戶外景觀照明、路燈電纜敷設等場所。

　　·Aluminum alloy cable tray: lightweight, corrosion-resistant, and has good weather resistance, suitable for outdoor landscape lighting, street lamp cable laying, and other places.

　　· 玻璃鋼橋架：耐腐蝕、絕緣性能好，適用于沿海地區、化工園區等戶外腐蝕性較強的環境，但需注意其耐候性問題，必要時可采取防護措施。

　　·Fiberglass cable tray: corrosion-resistant and has good insulation performance, suitable for outdoor corrosive environments such as coastal areas and chemical parks. However, attention should be paid to its weather resistance, and protective measures can be taken if necessary.
