济南人必看！铝合金电缆桥架选对厚度，耐用又省心，90%的人选错踩坑

　　Jinan people must watch! Choosing the right thickness for aluminum alloy cable trays is durable and worry free, with 90% of people choosing the wrong one to step on

　　在济南，不管是泉城广场周边的写字楼、高新区的产业园，还是章丘的工厂车间、长清的住宅小区，建筑用电离不开电缆桥架，而铝合金桥架凭借轻便、耐腐蚀、颜值高的优势，早已成为济南多数建筑的。但很多济南朋友在选铝合金电缆桥架时，总容易忽略一个关键问题——厚度，殊不知，厚度直接决定桥架的强度和耐用性，选薄了易变形、用不久，选厚了多花钱、没必要。今天就用大白话+实打实的数据，给济南的朋友唠透济南铝合金电缆桥架，说说厚度怎么选，看完再也不踩坑。

　　In Jinan, whether it is the office buildings around Quancheng Square, the industrial park in the High tech Zone, the factory workshops in Zhangqiu, or the residential areas in Changqing, aluminum alloy cable trays have become the preferred choice for many buildings in Jinan due to their lightweight, corrosion-resistant, and high aesthetic value. But many friends in Jinan tend to overlook a key issue when choosing aluminum alloy cable trays - thickness. Little do they know, thickness directly determines the strength and durability of the tray. Choosing a thinner one is prone to deformation and will not last long, while choosing a thicker one costs more and is unnecessary. Today, using plain language and practical data, I will talk to my friends in Jinan about the aluminum alloy cable tray in Jinan, with a focus on how to choose the thickness. After reading, I will never get stuck again.

　　先给大家科普个基础常识：济南铝合金电缆桥架，本质是电缆的“防护衣+支撑架”，和普通钢制桥架相比，它以铝为基，添加铜、硅、镁等合金元素，密度低但强度接近钢，重量比钢制桥架轻30%-40%，安装更省力，还自带优良的抗腐蚀性，尤其适配济南夏季多雨、部分区域潮湿的气候，不用频繁维护，使用寿命更长，这也是它在济南建筑中使用率逐年提升的原因，目前济南新建建筑中，铝合金桥架使用率已达65%以上。

　　First of all, let me give you some basic knowledge: Jinan aluminum alloy cable tray is essentially a "protective suit+support frame" for cables. Compared with ordinary steel cable trays, it is based on aluminum and adds alloy elements such as copper, silicon, magnesium, etc. It has low density but strength close to high-quality steel. Its weight is 30% -40% lighter than steel bridge frames, and it is easier to install. It also has excellent corrosion resistance, especially suitable for the rainy summer and humid climate in some areas of Jinan. It does not require frequent maintenance and has a longer service life. This is also the reason why its usage rate in Jinan buildings has been increasing year by year. Currently, the usage rate of aluminum alloy cable trays in newly-built buildings in Jinan has reached over 65%.

　　来了，铝合金桥架的厚度选择，可不是凭感觉，有明确的国标要求和场景适配标准，这也是很多人选错的核心原因。根据CECS 106-2000标准规定，济南铝合金电缆桥架的厚度的常规范围在1.5mm-3mm之间，不同厚度对应不同的承载能力和应用场景，没有的厚度，只有适配的选择，结合济南本地建筑特点，给大家拆解的明明白白，一看就懂。

　　The key point is that the thickness selection of aluminum alloy cable trays is not based on intuition. There are clear national standard requirements and scene adaptation standards, which is also the core reason why many people make mistakes. According to the national CECS 106-2000 standard, the conventional range of thickness for aluminum alloy cable trays in Jinan is between 1.5mm-3mm. Different thicknesses correspond to different bearing capacities and application scenarios, and there is no best thickness, only the most suitable choice. Combined with the local architectural characteristics of Jinan, we will explain it clearly and easily.

　　种，1.5mm厚的铝合金桥架，属于“常规家用/轻载款”，也是济南住宅小区、小型写字楼常用的规格，占济南铝合金桥架市场用量的40%左右。它的承载能力可达2.5kN/m，每米可承重60-80kg，刚好适配室内砌体墙、混凝土结构或吊顶构造，比如济南多数小区的楼道照明电缆、家用弱电电缆，以及小型写字楼的办公用电线路，这些场景电缆数量少、重量轻，不用承受过大压力，1.5mm厚度完全够用。

　　The first type is a 1.5mm thick aluminum alloy bridge, which belongs to the "conventional household/light load" category and is also the most commonly used specification in residential communities and small office buildings in Jinan, accounting for about 40% of the aluminum alloy bridge market usage in Jinan. Its load-bearing capacity can reach 2.5kN/m, with a capacity of 60-80kg per meter, which is just suitable for indoor masonry walls, concrete structures, or suspended ceiling structures. For example, the lighting cables in most residential areas of Jinan, household weak current cables, and office power lines in small office buildings have fewer cables, lighter weight, and do not need to withstand excessive pressure. A thickness of 1.5mm is completely sufficient.

　　这种厚度的铝合金桥架，性价比极高，济南本地市场价大概28-45元/米，表面经过阳极氧化处理，镀层厚度≥15μm，盐雾测试≥480小时，在济南室内干燥环境下，使用寿命可达12-15年，而且重量轻，每米仅重2.2-2.8kg，工人安装时不用额外借助大型设备，施工效率比钢制桥架提升25%，特别适合室内轻载场景。

　　This thickness of aluminum alloy bridge has extremely high cost-effectiveness, with a local market price of about 28-45 yuan/meter in Jinan. The surface has undergone anodizing treatment, with a coating thickness of ≥ 15 μ m and a salt spray test of ≥ 480 hours. In a dry indoor environment in Jinan, the service life can reach 12-15 years, and the weight is light, only 2.2-2.8kg per meter. Workers do not need to rely on large equipment for installation, and the construction efficiency is 25% higher than that of steel bridge, making it particularly suitable for indoor light load scenarios.

　　第二种，2mm厚的铝合金桥架，属于“中载款”，适配场景更广泛，占济南铝合金桥架市场用量的35%。它的承载能力提升4kN/m，每米可承重100-120kg，比1.5mm厚的桥架强度提升60%，主要用于建筑外墙、室内需较强承载能力的场所，比如济南高新区产业园的车间设备电缆、写字楼的空调电缆，以及沿街商铺的户外供电线路。

　　The second type, 2mm thick aluminum alloy cable tray, belongs to the "mid-range model" and has a wider range of adaptability scenarios, accounting for 35% of the Jinan aluminum alloy cable tray market usage. Its load-bearing capacity has been increased to 4kN/m, with a capacity of 100-120kg per meter, which is 60% stronger than a 1.5mm thick bridge. It is mainly used in places where strong load-bearing capacity is required, such as workshop equipment cables in Jinan High tech Zone Industrial Park, central air conditioning cables in office buildings, and outdoor power supply lines for shops along the street.

　　济南夏季多雨、冬季多风，建筑外墙的桥架要承受风雨侵蚀和一定的外力冲击，2mm厚的铝合金桥架，板材经过特殊挤压成型处理，抗变形能力更强，不易被风吹变形，表面采用静电喷塑或阳极氧化处理，耐腐蚀性更优，在济南户外潮湿环境下，使用寿命可达10-12年，济南本地市场价大概40-65元/米，兼顾实用性和经济性，是多数中载场景的。

　　Jinan is rainy in summer and windy in winter. The bridge frames on the exterior walls of buildings have to withstand wind and rain erosion and certain external impacts. The 2mm thick aluminum alloy bridge frames are specially extruded and processed to have stronger deformation resistance and are not easily deformed by wind. The surface is treated with electrostatic spraying or anodizing, which has better corrosion resistance. In the humid outdoor environment of Jinan, the service life can reach 10-12 years. The local market price in Jinan is about 40-65 yuan/meter, which combines practicality and economy and is the first choice for most medium load scenarios.

　　第三种，3mm厚的铝合金桥架，属于“重载款”，针对性解决大跨度、高承载的需求，占济南铝合金桥架市场用量的25%。它的承载能力可达6kN/m，每米可承重150-180kg，强度是1.5mm厚桥架的2.4倍，主要用于大跨度工厂、机场、车站、大型场馆等场所，比如济南遥墙国际机场的供电电缆、章丘大型工厂的生产线电缆，以及西客站周边的市政供电线路。

　　The third type is a 3mm thick aluminum alloy bridge frame, which belongs to the "heavy-duty model" and specifically solves the demand for large-span and high load-bearing capacity, accounting for 25% of the aluminum alloy bridge frame market in Jinan. Its load-bearing capacity can reach 6kN/m, with a capacity of 150-180kg per meter, and its strength is 2.4 times that of a 1.5mm thick bridge. It is mainly used in large-span factories, airports, stations, large venues and other places, such as the power supply cables of Jinan Yaoqiang International Airport, the production line cables of Zhangqiu Large Factory, and the municipal power supply lines around Xike Station.

　　这类场景的桥架跨度大（多在3-6米），电缆数量多、重量大，对强度要求极高，3mm厚的铝合金桥架，采用加厚合金板材，经过热处理强化，抗挠度极强，跨度6米时也不会变形，表面采用高端阳极氧化处理，耐腐蚀性和耐磨性拉满，在济南户外复杂环境下，使用寿命可达15-20年，济南本地市场价大概70-110元/米，虽然偏高，但耐用性和性有保障，避免后期频繁更换带来的麻烦和损失。

　　The bridge span of this type of scenario is large (mostly 3-6 meters), with a large number and weight of cables, requiring extremely high strength. The 3mm thick aluminum alloy bridge is made of thickened alloy sheet and strengthened by heat treatment, which has strong resistance to deflection and will not deform even when the span is 6 meters. The surface is treated with high-end anodizing, which has full corrosion resistance and wear resistance. In the complex outdoor environment of Jinan, the service life can reach 15-20 years. The local market price in Jinan is about 70-110 yuan/meter. Although the price is high, the durability and safety are guaranteed, avoiding the trouble and loss caused by frequent replacement in the later stage.

　　补充一组济南本地实用提醒，帮大家避坑：很多商家为了省钱，会用1.2mm厚的铝合金桥架冒充1.5mm厚的，厚度不达标，强度会降低40%以上，用不了3年就会变形、损坏，济南朋友选购时，一定要用卡尺实测厚度，误差不能超过±0.1mm，同时认准济南本地正规厂家，比如济南畅通实业、山东增利来等，这些厂家的产品严格遵循国标生产，质保期≥5年，售后更有保障。

　　Add a set of practical reminders from Jinan to help everyone avoid pitfalls: Many businesses use 1.2mm thick aluminum alloy bridge frames to impersonate 1.5mm thick ones in order to save money. If the thickness does not meet the standard, the strength will decrease by more than 40%, and it will deform and be damaged in less than 3 years. When purchasing, friends in Jinan must use calipers to measure the thickness, and the error cannot exceed ± 0.1mm. At the same time, they should identify local legitimate manufacturers in Jinan, such as Jinan Tongtong Industrial and Shandong Zenglilai. The products of these manufacturers strictly follow the national standard production, with a warranty period of ≥ 5 years and more guaranteed after-sales service.

　　总结来说，济南铝合金电缆桥架的厚度选择，核心就是“按需选”，1.5mm适配室内轻载、2mm适配中载及户外、3mm适配重载及大跨度，遵循国标要求，结合自己的使用场景和电缆重量，不用盲目追求厚款，也不能为了省钱选薄款。选对厚度，既能保证电缆，又能节省成本、延长使用寿命，不管是家用、商用还是工业用，只要选对了，济南铝合金电缆桥架就能默默守护用电，成为建筑里不可或缺的“隐形功臣”。

　　In summary, the core of thickness selection for Jinan aluminum alloy cable trays is "on-demand selection". 1.5mm is suitable for indoor light loads, 2mm is suitable for medium loads and outdoor loads, and 3mm is suitable for heavy loads and large-span. It follows national standards and combines with its own usage scenarios and cable weight. There is no need to blindly pursue thicker versions, nor should thinner versions be chosen to save money. Choosing the right thickness can ensure cable safety, save costs, and extend service life. Whether for household, commercial, or industrial use, as long as the thickness is chosen correctly, Jinan aluminum alloy cable trays can silently protect electrical safety and become an indispensable "invisible hero" in construction.
