The bridge frame inside the building can be independently erected or laid on various buildings and pipe gallery supports, and should reflect the characteristics of simple structure, beautiful appearance, flexible configuration, and easy maintenance.

　　根据使用环境和功能要求，我们要选择相应材质的桥架，电缆桥架的主要材质包括金属、铝合金和玻璃钢。金属桥架具有强度高、承载能力强和良好的防火性能，适用于各种工业和商业场所，尤其是在对承载要求较高的环境中使用。铝合金桥架质量轻、外形美观、耐腐蚀，适用于需要轻量化和美观要求的场所。玻璃钢桥架具有良好的耐腐蚀、耐老化和绝缘性能，适用于各种恶劣环境。

　　According to the usage environment and functional requirements, we need to choose cable trays made of corresponding materials. The main materials for cable trays include metal, aluminum alloy, and fiberglass.

　　二、几种常用材质的桥架区别

　　2、 Difference between several commonly used bridge materials

　　1、冷（电）镀锌桥架和热镀锌桥架的区别生成原理冷镀锌：冷镀锌是将钢材质或产品在锌的溶液里浸泡或电解，导致材质或产品表面有一层比较薄的锌。这种方法是通过电化学原理在钢铁器件上沉积一层锌。热镀锌：热镀锌是将铁材质或其他金属在加热的锌液中发生电解反应，使其表面形成一种厚厚的锌表层。这种方法是通过将钢制器件浸入熔融锌液中，获得金属镀层。抗腐蚀性冷镀锌：由于表面只有一层薄薄的锌保护层，冷镀锌桥架的抗腐蚀性较差，容易发生腐蚀，导致锌脱落。热镀锌：热镀锌桥架表面有一层厚厚的金属保护层，不容易脱落，抗腐蚀性较强，使用寿命较长。使用范围冷镀锌：冷镀锌一般用于钢筋、护栏、扶手等地方。热镀锌：热镀锌一般用于通信塔、铁路、公路结构件、船上结构件等需要高强度防腐的场合。工艺、厚度和工艺：冷镀锌是通过电镀设备进行电化学沉积，热镀锌是通过将钢制器件浸入熔融锌液中完成镀锌处理。厚度：热镀锌桥架的镀层厚度一般较厚，抗腐蚀能力强，冷镀锌桥架的镀层厚度较薄，抗腐蚀能力较弱。：热镀锌桥架质量较好，成本较高，因此也较高；冷镀锌桥架相对较低，但耐用性较差。表面特征冷镀锌桥架：表面较光滑，不易出现结块等现象。热镀锌桥架：外观稍显粗糙，会产生工艺水纹等特征。

　　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.

　　热镀锌桥架在抗腐蚀性、使用寿命和适用范围上优于冷镀锌桥架，但较高；冷镀锌桥架则较低，适用于对防腐要求不高的场合。2、不锈钢桥架和镀锌桥架的区别材料和防腐蚀性能不锈钢桥架：由不锈钢材料制成，具有优异的抗氧化和抗腐蚀性能。不锈钢对潮湿、酸碱性环境具有很强的耐腐蚀性，特别适合用于室外或化工厂等腐蚀性较强的环境。

　　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.

　　镀锌桥架：由普通钢材经过热浸镀锌工艺处理而成，表面镀有一层锌涂层以增加耐腐蚀性。虽然镀锌能提供一定程度的防腐蚀保护，但其耐腐蚀性能较弱，长期使用或极端环境下锌涂层可能会磨损或受损。适用环境不锈钢桥架：适用于高湿度、高盐雾或化学腐蚀严重的环境，如沿海地区、化工厂、食品加工厂等。其优异的耐腐蚀性能使其在恶劣环境下仍能长期保持表面光洁和抗腐蚀性。

　　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.

　　镀锌桥架：适用于一般室内和室外环境，其防腐蚀性能能够满足一般的电缆支架需求，但在特殊的腐蚀性环境下可能需要采取其他防腐蚀措施。维护需求不锈钢桥架：由于其天然的抗腐蚀能力，基本无需维护，可以长时间使用且外观持久美观。镀锌桥架：需要定期检查和维护，尽管可以通过热浸镀锌、喷塑等防腐处理延长使用寿命，但仍需定期维护。经济性不锈钢桥架：初期投资较高，但几乎不需要后续维护，使用寿命长，长远来看可能更具经济性。

　　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.

　　镀锌桥架：初期投资较低，但需要考虑长期的维护成本和可能的更换费用。

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

　　这两种桥架的性能特点都差不多相同，都是具有不错的耐腐蚀、耐老化、耐磨损性能，可以很好地保护电缆线路不受到伤害。但是由于不锈钢的成本过高，所以不锈钢桥架的采用率就没有镀锌桥架的高，很多用户选择的都是镀锌桥架。

　　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.

　　在实际施工过程中，我们要根据负载能力、安装环境、布局要求等方面选择合适的桥架，以确保电缆系统的性、稳定性和经济性。

　　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.
