不同材質電纜橋架的成本差異

　　Cost differences of cable trays made of different materials

　　鋼制橋架：

　　Steel bridge frame:

　　成本構成：主要選用冷軋鋼板，其成本相對較為穩定。在表面處理方面，熱鍍鋅、冷鍍鋅、烤漆、防火涂料、靜電噴涂等工藝會增加一定成本。但由于鋼材的生產技術成熟，產量大，其原材料成本相對可控。

　　Cost composition: We mainly use high-quality cold-rolled steel plates, which have relatively stable costs. In terms of surface treatment, processes such as hot-dip galvanizing, cold galvanizing, baking paint, fireproof coatings, and electrostatic spraying will increase certain costs. However, due to the mature production technology and large output of steel, its raw material costs are relatively controllable.

　　成本特點：總體成本處于中等水平。在一些對強度要求較高的場合，鋼制橋架具有一定的優勢。然而，其重量較大，可能會增加運輸和安裝成本。

　　Cost characteristics: The overall cost is at a moderate level. In some situations where high strength is required, steel cable trays have certain advantages. However, its heavy weight may increase transportation and installation costs.

　　鋁合金橋架：

　　Aluminum alloy bridge frame:

　　成本構成：鋁合金材料本身相對較高，但具有重量輕、耐腐蝕等優點。其表面處理工藝與鋼制橋架類似，也會增加一定成本。

　　Cost composition: Aluminum alloy materials themselves are relatively expensive, but they have advantages such as light weight and corrosion resistance. The surface treatment process is similar to that of steel cable trays, but it will also increase certain costs.

　　成本特點：成本相對較高。但由于其重量輕，運輸和安裝成本相對較低。在一些對重量有嚴格要求的場合，如高層建筑、石油化工等領域，鋁合金橋架具有一定的市場競爭力。

　　Cost characteristics: The cost is relatively high. However, due to its light weight, transportation and installation costs are relatively low. In some situations where weight is strictly required, such as high-rise buildings, petrochemicals, etc., aluminum alloy cable trays have certain market competitiveness.

　　復合橋架：

　　Composite bridge frame:

　　成本構成：以鋼板或鋁合金為基材的復合橋架，結合了兩種材料的優點，成本相對較高。其制造工藝相對復雜，也會增加成本。

　　Cost composition: Composite cable trays based on steel plates or aluminum alloys combine the advantages of both materials, resulting in relatively high costs. Its manufacturing process is relatively complex and also increases costs.

　　成本特點：成本較高，但在防腐性能和強度方面具有優勢。在一些惡劣環境下，如石油化工重腐蝕環境，復合橋架的使用可以降低后期維護成本。

　　Cost characteristics: The cost is relatively high, but it has advantages in terms of anti-corrosion performance and strength. In some harsh environments, such as heavily corrosive environments in the petrochemical industry, the use of composite cable trays can reduce maintenance costs in the later stages.

　　高分子合金橋架：

　　Polymer alloy bridge frame:

　　成本構成：高分子合金材料的研發和生產成本相對較高。但其具有強度高、重量輕、易安裝、耐腐蝕等優點，減少了后期維護成本。

　　Cost composition: The research and production costs of polymer alloy materials are relatively high. But it has the advantages of high strength, light weight, easy installation, and corrosion resistance, which reduces maintenance costs in the later stage.

　　成本特點：初期成本較高，但從長期來看，由于其優異的性能和低維護成本，具有一定的經濟優勢。

　　Cost characteristics: The initial cost is relatively high, but in the long run, it has certain economic advantages due to its excellent performance and low maintenance costs.

　　PVC 橋架：

　　PVC bridge frame:

　　成本構成：PVC 是一種通用型塑料，經濟。但其加工性差、韌性不足、耐熱性差等問題，需要進行改進，這會增加一定成本。

　　Cost composition: PVC is a universal plastic with an economical price. However, its poor processability, insufficient toughness, and poor heat resistance require improvement, which will increase certain costs.

　　成本特點：成本較低。在一些對成本敏感的場合，如小型建筑項目中，PVC 橋架可能具有一定的市場份額。但由于其性能限制，應用范圍相對較窄。

　　Cost characteristics: Low cost. In some cost sensitive situations, such as small construction projects, PVC cable trays may have a certain market share. However, due to its performance limitations, its application scope is relatively narrow.
