金属材质桥架：​

Metal material bridge frame:

镀锌桥架：镀锌桥架在济南使用广泛，它分为热镀锌和电镀锌。热镀锌桥架的锌层较厚，具有出色的防腐蚀性能，能有效抵御潮湿、酸碱等恶劣环境的侵蚀，使用寿命长，常用于户外、地下室等环境较为复杂的场所，如济南的市政道路路灯电缆敷设，热镀锌桥架可保障电缆在长期风吹日晒雨淋的条件下稳定运行。电镀锌桥架的锌层相对较薄，成本也较低，一般适用于室内干燥环境，像普通居民楼、办公楼内的电缆敷设。​

Galvanized cable tray: Galvanized cable tray is widely used in Jinan, and it is divided into hot-dip galvanizing and electroplating galvanizing. The zinc layer of hot-dip galvanized cable trays is thick and has excellent corrosion resistance, which can effectively resist the erosion of harsh environments such as humidity, acidity, and alkalinity. It has a long service life and is commonly used in outdoor and underground environments with complex environments, such as the laying of municipal road light cables in Jinan. Hot dip galvanized cable trays can ensure stable operation of cables under long-term wind, sun, and rain conditions. The zinc layer of electroplated galvanized cable trays is relatively thin and cost-effective, making them generally suitable for indoor dry environments such as cable laying in ordinary residential and office buildings. ​

不锈钢桥架：不锈钢桥架材质坚固，具有极高的耐腐蚀性，尤其适合在有强腐蚀介质的环境中使用，如化工企业、沿海地区等。其外观美观大方，且维护成本低，在济南的一些高端商业建筑或对桥架耐久性要求极高的特殊工业项目中，不锈钢桥架是理想之选。​

Stainless steel cable tray: The material of stainless steel cable tray is sturdy and has extremely high corrosion resistance, especially suitable for use in environments with strong corrosive media, such as chemical enterprises, coastal areas, etc. Its appearance is beautiful and elegant, and the maintenance cost is low. In some high-end commercial buildings or special industrial projects in Jinan that require high durability of cable trays, stainless steel cable trays are the ideal choice. ​

铝合金桥架：铝合金桥架重量轻，安装便捷，同时具备良好的耐腐蚀性和导电性。它的外观具有金属质感，较为美观，常用于对重量有要求且需要一定导电性的场所，如数据中心，铝合金桥架既能满足大量电缆敷设的需求，又因其良好的导电性，在应对电气故障时能快速导除电流，保障设备。​

Aluminum alloy bridge: Aluminum alloy bridge is lightweight, easy to install, and has good corrosion resistance and conductivity. Its appearance has a metallic texture and is relatively beautiful. It is commonly used in places that require weight and a certain degree of conductivity, such as data centers. Aluminum alloy cable trays can meet the needs of a large number of cable laying, and due to their good conductivity, they can quickly conduct current when dealing with electrical faults, ensuring equipment safety. ​

非金属材质桥架：​

Non metallic material bridge:

玻璃钢桥架：玻璃钢桥架由玻璃纤维增强塑料制成，具有轻质高强、耐腐蚀、绝缘性能好等优点。它的耐候性强，能在户外长期使用而不老化，特别适用于化工、冶金等行业中具有腐蚀性气体或液体的环境，以及对电气绝缘要求高的场所，如变电站的电缆敷设。​

Fiberglass bridge: Fiberglass bridge is made of fiberglass reinforced plastic, which has the advantages of lightweight, high strength, corrosion resistance, and good insulation performance. It has strong weather resistance and can be used outdoors for a long time without aging. It is particularly suitable for environments with corrosive gases or liquids in industries such as chemical and metallurgical, as well as places with high electrical insulation requirements, such as cable laying in substations. ​

防火桥架：防火桥架并非单一材质，它通常是在普通桥架的基础上，采用防火板材或添加防火涂层制成。在济南的人员密集场所，如、医院、学校等，以及对消防要求极高的建筑，如高层建筑的消防用电线路敷设，防火桥架必不可少。它能在火灾发生时，在一定时间内阻止火势蔓延，保护电缆的正常运行，为人员疏散和消防救援争取宝贵时间。​​

Fireproof bridge: Fireproof bridge is not made of a single material, it is usually made of fireproof board or added with fireproof coating on the basis of ordinary bridge. In densely populated places in Jinan, such as shopping malls, hospitals, schools, and buildings with extremely high fire safety requirements, such as the laying of fire protection power lines in high-rise buildings, fire-resistant cable trays are essential. It can prevent the spread of fire for a certain period of time when a fire occurs, protect the normal operation of cables, and buy valuable time for personnel evacuation and firefighting rescue. ​​
