跟着全球工业化与城市化进程的加快，电缆桥架作为电力、通讯、交通等范畴支撑设备，其牢靠性与耐久性成为工程质量的要害指标。热镀锌电缆桥架凭借其优异的防腐功能、高强度承载才能及特性，正逐渐成为市政工程、新能源项目及修建的解决计划。

　　With the acceleration of global industrialization and urbanization, cable trays, as supporting equipment in the fields of power, communication, transportation, etc., have become key indicators of engineering quality in terms of reliability and durability. Hot dip galvanized cable trays are gradually becoming a solution for municipal engineering, new energy projects, and construction due to their excellent anti-corrosion function, high-strength load-bearing capacity, and environmental protection characteristics.

　　一、技能革新：从工艺到功能的晋级 热镀锌工艺经过将钢材浸入熔融锌液，构成厚度均匀的锌铁合金层，使桥架表面耐腐蚀性提升3-5倍，可在酸雨、盐雾等恶劣环境中保持10年以上无锈蚀。例如，国道317线鹧鸪山地道改迁工程中，新增的2500个热镀锌立柱及托臂在杂乱地质条件下完成了零维护运行。此外，梯度镀锌技能（内层锌镍合金+外层纯锌）将盐雾测试时长提升4800小时，远超国标要求，一起选用冷轧钢带（屈从强度350MPa）使自重下降12%，完成了轻量化与高强度的平衡。

　　1、 Skill innovation: Upgrading from process to function. The hot-dip galvanizing process involves immersing steel in molten zinc to form a uniformly thick layer of zinc iron alloy, which increases the corrosion resistance of the bridge surface by 3-5 times. It can maintain corrosion free for more than 10 years in harsh environments such as acid rain and salt spray. For example, in the Zhegushan Tunnel Relocation Project of National Highway 317, the newly added 2500 hot-dip galvanized columns and brackets completed zero maintenance operation under chaotic geological conditions. In addition, the gradient galvanizing technique (inner layer of zinc nickel alloy+outer layer of pure zinc) has increased the salt spray testing time to 4800 hours, far exceeding the national standard requirements. Cold rolled steel strips (yield strength of 350MPa) were selected together to reduce self weight by 12%, achieving a balance between lightweight and high-strength.

　　二、应用场景：从传统基建到新式范畴的广泛掩盖 热镀锌桥架已深度融入智慧城市建造的各个环节：在市政工程中，地铁、高架照明体系遍及选用其作为电缆支撑载体，施工功率提升30%；在新能源范畴，上海奉贤分布式光伏项目经过热镀锌槽式桥架完成了房顶电缆的敷设，兼顾抗风荷载与长时间耐候性；在工业范畴，南水北调中线泵站、滨海燃煤电厂等重大项目中，热镀锌桥架以“零毛病”体现保证了电力体系的稳定运行。

　　2、 Application scenarios: From traditional infrastructure to new categories, hot-dip galvanized cable trays have been deeply integrated into various aspects of smart city construction. In municipal engineering, they are widely used as cable support carriers for subway and elevated lighting systems, increasing construction power by 30%; In the field of new energy, the Shanghai Fengxian distributed photovoltaic project has completed the laying of roof cables through hot-dip galvanized trough type cable trays, balancing wind resistance and long-term weather resistance; In the industrial sector, in major projects such as the South to North Water Diversion Middle Route Pump Station and Binhai Coal fired Power Plant, hot-dip galvanized cable trays ensure the stable operation of the power system with "zero problems".

　　三、趋势：方针驱动与绿色转型双轮发力 在“双碳”战略与新基建方针推进下，热镀锌桥架呈现高速增加态势。2023年全球规模打破200亿元，估计2025年将达280亿元，年复合增加率超10%。这一增加得益于三大要素：一是智能电网、5G基站等新式基础设施对高牢靠桥架的需求激增；二是绿色修建标准要求资料可回收、低能耗，热镀锌桥架的全生命周期碳排较传统产品下降62%；三是当地方针支撑，如河北廊坊对电缆桥架企业给予研制费用加计扣除、技改补助等优惠，推进本地企业技能晋级。

　　3、 Market trend: Driven by policy and green transformation, the hot-dip galvanized bridge shopping mall is showing a rapid growth trend under the promotion of the "dual carbon" strategy and the new infrastructure policy. In 2023, the global shopping mall scale will exceed 20 billion yuan, and it is estimated to reach 28 billion yuan by 2025, with a compound annual growth rate of over 10%. This increase is due to three major factors: firstly, the surge in demand for high reliability cable trays in new infrastructure such as smart grids and 5G base stations; Secondly, the green construction standard requires that the data be recyclable and have low energy consumption. The carbon emissions of hot-dip galvanized cable trays throughout their entire lifecycle are reduced by 62% compared to traditional products; The third is the support of local policies, such as the additional deduction of research and development expenses and technical renovation subsidies provided to cable tray enterprises in Langfang, Hebei, to promote the skill upgrading of local enterprises.

　　四、企业实践：技能打破与产业协同的典范 作为热镀锌桥架范畴的领军企业，河北隆鑫电气经过引入激光切开+机器人焊接产线，将资料利用率提升92%，并参加拟定多项职业标准。其研制的防火型热镀锌桥架经过GB/T 9978耐火测试（耐火90分钟），已应用于北京大兴机场等项目。一起，企业积极响应区域产业方针，与香河本地锌冶炼厂树立起浮定价机制，确定原资料成本上限，构成从镀锌到安装的完好产业链。

　　4、 Enterprise Practice: As a leading enterprise in the field of hot-dip galvanized cable trays, Hebei Longxin Electric has introduced a laser cutting+robot welding production line, which has increased the data utilization rate to 92% and participated in the formulation of multiple occupational standards. The fire-resistant hot-dip galvanized cable tray developed by it has passed the GB/T 9978 fire resistance test (90 minutes of fire resistance) and has been applied in projects such as Beijing Daxing Airport. Together, the enterprise actively responds to the regional industrial policy, establishes a floating pricing mechanism with the local zinc smelter in Xianghe, determines the upper limit of raw material costs, and forms a complete industrial chain from galvanizing to installation.

　　五、未来展望：智能化与可持续发展的深度融合 跟着EPD（环境产品声明）认证在全球供应链中的普及，热镀锌桥架企业正加快布局全生命周期环境数据管理。例如，经过二维码数字身份证完成出产批次、检测陈述的全程追溯，满足苹果、微软等世界客户的绿色收购要求。此外，BIM模型库的开发（掩盖100+场景）可缩短规划周期70%，推进桥架体系向模块化、智能化方向晋级。 在“十四五”新式基础设施建造的浪潮中，热镀锌电缆桥架凭借技能迭代、场景拓宽与方针红利的多重优势，正从“资料供应商”向“体系解决计划提供商”转型。这一革新不仅为职业带来千亿级机遇，更将为全球基础设施的运行提供我国计划。

　　5、 Future prospects: With the deep integration of intelligence and sustainable development and the popularization of EPD (Environmental Product Declaration) certification in the global supply chain, hot-dip galvanized cable tray enterprises are accelerating the layout of full lifecycle environmental data management. For example, the full traceability of production batches and testing statements through QR code digital ID cards meets the green acquisition requirements of global customers such as Apple and Microsoft. In addition, the development of BIM model libraries (covering over 100 scenarios) can shorten the planning cycle by 70% and promote the upgrading of bridge systems towards modularity and intelligence. In the wave of new infrastructure construction during the 14th Five Year Plan period, hot-dip galvanized cable trays are transforming from "data suppliers" to "system solution plan providers" with multiple advantages of skill iteration, scene expansion, and policy dividends. This innovation not only brings billions of opportunities in the professional market, but also provides China's plan for the safe operation of global infrastructure.
