　　不銹鋼電纜橋架：不銹鋼橋架采用的是304不銹鋼材質經過裁剪、折彎制作而成的一種橋架，具有非常耐腐蝕、耐沖擊、不易銹蝕的特點。所以不銹鋼橋架是用來敷設安裝重腐蝕、潮濕地區電纜線路的不錯選擇。特點：在各類橋架優越的基礎上，著重在隔熱、散熱、防火方面加以改進，具有非常耐腐蝕、耐沖擊、不易銹蝕的特點，適用場景：適用于電廠、海邊、食品廠、化工廠等環境。

　　二、幾種常用材質的橋架區別

　　2、 Difference between several commonly used bridge materials

　　1、冷（電）鍍鋅橋架和熱鍍鋅橋架的區別生成原理冷鍍鋅：冷鍍鋅是將鋼材質或產品在鋅的溶液里浸泡或電解，導致材質或產品表面有一層比較薄的鋅。這種方法是通過電化學原理在鋼鐵器件上沉積一層鋅。熱鍍鋅：熱鍍鋅是將鐵材質或其他金屬在加熱的鋅液中發生電解反應，使其表面形成一種厚厚的鋅表層。這種方法是通過將鋼制器件浸入熔融鋅液中，獲得金屬鍍層。抗腐蝕性冷鍍鋅：由于表面只有一層薄薄的鋅保護層，冷鍍鋅橋架的抗腐蝕性較差，容易發生腐蝕，導致鋅脫落。熱鍍鋅：熱鍍鋅橋架表面有一層厚厚的金屬保護層，不容易脫落，抗腐蝕性較強，使用壽命較長。使用范圍冷鍍鋅：冷鍍鋅一般用于鋼筋、護欄、扶手等地方。熱鍍鋅：熱鍍鋅一般用于通信塔、鐵路、公路結構件、船上結構件等需要高強度防腐的場合。工藝、厚度和工藝：冷鍍鋅是通過電鍍設備進行電化學沉積，熱鍍鋅是通過將鋼制器件浸入熔融鋅液中完成鍍鋅處理。厚度：熱鍍鋅橋架的鍍層厚度一般較厚，抗腐蝕能力強，冷鍍鋅橋架的鍍層厚度較薄，抗腐蝕能力較弱。：熱鍍鋅橋架質量較好，成本較高，因此也較高；冷鍍鋅橋架相對較低，但耐用性較差。表面特征冷鍍鋅橋架：表面較光滑，不易出現結塊等現象。熱鍍鋅橋架：外觀稍顯粗糙，會產生工藝水紋等特征。

　　1. The difference between cold (electric) galvanized bridge and hot-dip galvanized bridge is based on the principle of cold galvanizing: Cold galvanizing is the process of soaking or electrolyzing steel materials or products in a zinc solution, resulting in a relatively thin layer of zinc on the surface of the material or product. This method involves depositing a layer of zinc on steel components through electrochemical principles. Hot dip galvanizing: Hot dip galvanizing is the process of electrolyzing iron or other metals in heated zinc solution, forming a thick layer of zinc on its surface. This method involves immersing steel components in molten zinc to obtain a metal coating. Corrosion resistant cold dip galvanizing: Due to the thin layer of zinc protection on the surface, the corrosion resistance of cold dip galvanized cable trays is poor and prone to corrosion, resulting in zinc detachment. Hot dip galvanizing: The surface of the hot-dip galvanized bridge has a thick metal protective layer that is not easily peeled off, has strong corrosion resistance, and has a long service life. Scope of use: Cold galvanizing is generally used for steel bars, guardrails, handrails, and other places. Hot dip galvanizing: Hot dip galvanizing is generally used in communication towers, railways, highway structural components, ship structural components and other occasions that require high-strength anti-corrosion. Process, thickness, and price: Cold galvanizing is achieved through electrochemical deposition using electroplating equipment, while hot-dip galvanizing is achieved by immersing steel components in molten zinc solution for galvanizing treatment. Thickness: The coating thickness of hot-dip galvanized cable trays is generally thicker and has strong corrosion resistance, while the coating thickness of cold-dip galvanized cable trays is thinner and has weaker corrosion resistance. Price: Hot dip galvanized cable trays have better quality and higher costs, so the price is also higher; Cold galvanized cable trays are relatively inexpensive, but their durability is poor. Surface features: Cold galvanized bridge tray: The surface is relatively smooth and not prone to agglomeration and other phenomena. Hot dip galvanized cable tray: The appearance is slightly rough and may produce features such as process water marks.

　　熱鍍鋅橋架在抗腐蝕性、使用壽命和適用范圍上優于冷鍍鋅橋架，但較高；冷鍍鋅橋架則較低，適用于對防腐要求不高的場合。2、不銹鋼橋架和鍍鋅橋架的區別材料和防腐蝕性能不銹鋼橋架：由不銹鋼材料制成，具有優異的抗氧化和抗腐蝕性能。不銹鋼對潮濕、酸堿性環境具有很強的耐腐蝕性，特別適合用于室外或化工廠等腐蝕性較強的環境。

　　Hot dip galvanized cable trays are superior to cold dip galvanized cable trays in terms of corrosion resistance, service life, and applicability, but they are more expensive; Cold galvanized cable trays have a lower price and are suitable for occasions where anti-corrosion requirements are not high. 2. The difference in materials and corrosion resistance between stainless steel bridge and galvanized bridge. Stainless steel bridge: made of stainless steel material, it has excellent oxidation resistance and corrosion resistance. Stainless steel has strong corrosion resistance to humid and acidic environments, making it particularly suitable for outdoor or chemical plants with strong corrosiveness.

　　鍍鋅橋架：由普通鋼材經過熱浸鍍鋅工藝處理而成，表面鍍有一層鋅涂層以增加耐腐蝕性。雖然鍍鋅能提供一定程度的防腐蝕保護，但其耐腐蝕性能較弱，長期使用或極端環境下鋅涂層可能會磨損或受損。適用環境不銹鋼橋架：適用于高濕度、高鹽霧或化學腐蝕嚴重的環境，如沿海地區、化工廠、食品加工廠等。其優異的耐腐蝕性能使其在惡劣環境下仍能長期保持表面光潔和抗腐蝕性。

　　Galvanized bridge: Made of ordinary steel through hot-dip galvanizing process, with a layer of zinc coating on the surface to increase corrosion resistance. Although galvanizing can provide a certain degree of corrosion protection, its corrosion resistance is weak, and the zinc coating may wear or be damaged under long-term use or extreme environments. Applicable environment: Stainless steel cable tray: suitable for environments with high humidity, high salt spray, or severe chemical corrosion, such as coastal areas, chemical plants, food processing plants, etc. Its excellent corrosion resistance enables it to maintain a smooth surface and corrosion resistance for a long time even in harsh environments.

　　鍍鋅橋架：適用于一般室內和室外環境，其防腐蝕性能能夠滿足一般的電纜支架需求，但在特殊的腐蝕性環境下可能需要采取其他防腐蝕措施。維護需求不銹鋼橋架：由于其天然的抗腐蝕能力，基本無需維護，可以長時間使用且外觀持久美觀。鍍鋅橋架：需要定期檢查和維護，盡管可以通過熱浸鍍鋅、噴塑等防腐處理延長使用壽命，但仍需定期維護。經濟性不銹鋼橋架：初期投資較高，但幾乎不需要后續維護，使用壽命長，長遠來看可能更具經濟性。

　　Galvanized cable tray: suitable for general indoor and outdoor environments, its anti-corrosion performance can meet the general requirements of cable supports, but other anti-corrosion measures may need to be taken in special corrosive environments. Maintenance requirements for stainless steel cable trays: Due to their natural corrosion resistance, they require minimal maintenance and can be used for a long time with a long-lasting and aesthetically pleasing appearance. Galvanized cable tray: Regular inspection and maintenance are required. Although anti-corrosion treatments such as hot-dip galvanizing and spray coating can extend its service life, regular maintenance is still necessary. Economical stainless steel bridge: The initial investment is relatively high, but there is almost no need for subsequent maintenance, and the service life is long. In the long run, it may be more economical.

　　鍍鋅橋架：初期投資較低，但需要考慮長期的維護成本和可能的更換費用。

　　Galvanized cable tray: The initial investment is relatively low, but long-term maintenance costs and possible replacement costs need to be considered.

　　這兩種橋架的性能特點都差不多相同，都是具有不錯的耐腐蝕、耐老化、耐磨損性能，可以很好地保護電纜線路不受到傷害。但是由于不銹鋼的成本過高，所以不銹鋼橋架的采用率就沒有鍍鋅橋架的高，很多用戶選擇的都是鍍鋅橋架。

　　The performance characteristics of these two types of cable trays are almost the same, both having good corrosion resistance, aging resistance, and wear resistance, which can effectively protect cable lines from damage. However, due to the high cost of stainless steel, the adoption rate of stainless steel cable trays is not as high as that of galvanized cable trays, and many users choose galvanized cable trays.

　　在實際施工過程中，我們要根據負載能力、安裝環境、布局要求等方面選擇合適的橋架，以確保電纜系統的性、穩定性和經濟性。

　　In the actual construction process, we need to choose suitable cable trays based on load capacity, installation environment, layout requirements, etc., to ensure the safety, stability, and economy of the cable system.
