濟南人必看！鋁合金電纜橋架選對厚度，耐用又省心，90%的人選錯踩坑

　　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

　　在濟南，不管是泉城廣場周邊的寫字樓、高新區(qū)的產(chǎn)業(yè)園，還是章丘的工廠車間、長清的住宅小區(qū)，建筑用電離不開電纜橋架，而鋁合金橋架憑借輕便、耐腐蝕、顏值高的優(yōu)勢，早已成為濟南多數(shù)建筑的。但很多濟南朋友在選鋁合金電纜橋架時，總?cè)菀缀雎砸粋€關(guān)鍵問題——厚度，殊不知，厚度直接決定橋架的強度和耐用性，選薄了易變形、用不久，選厚了多花錢、沒必要。今天就用大白話+實打?qū)嵉臄?shù)據(jù)，給濟南的朋友嘮透濟南鋁合金電纜橋架，說說厚度怎么選，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.

　　先給大家科普個基礎(chǔ)常識：濟南鋁合金電纜橋架，本質(zhì)是電纜的“防護衣+支撐架”，和普通鋼制橋架相比，它以鋁為基，添加銅、硅、鎂等合金元素，密度低但強度接近鋼，重量比鋼制橋架輕30%-40%，安裝更省力，還自帶優(yōu)良的抗腐蝕性，尤其適配濟南夏季多雨、部分區(qū)域潮濕的氣候，不用頻繁維護，使用壽命更長，這也是它在濟南建筑中使用率逐年提升的原因，目前濟南新建建筑中，鋁合金橋架使用率已達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%.

　　來了，鋁合金橋架的厚度選擇，可不是憑感覺，有明確的國標(biāo)要求和場景適配標(biāo)準(zhǔn)，這也是很多人選錯的核心原因。根據(jù)CECS 106-2000標(biāo)準(zhǔn)規(guī)定，濟南鋁合金電纜橋架的厚度的常規(guī)范圍在1.5mm-3mm之間，不同厚度對應(yīng)不同的承載能力和應(yīng)用場景，沒有的厚度，只有適配的選擇，結(jié)合濟南本地建筑特點，給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.

　　種，1.5mm厚的鋁合金橋架，屬于“常規(guī)家用/輕載款”，也是濟南住宅小區(qū)、小型寫字樓常用的規(guī)格，占濟南鋁合金橋架市場用量的40%左右。它的承載能力可達2.5kN/m，每米可承重60-80kg，剛好適配室內(nèi)砌體墻、混凝土結(jié)構(gòu)或吊頂構(gòu)造，比如濟南多數(shù)小區(qū)的樓道照明電纜、家用弱電電纜，以及小型寫字樓的辦公用電線路，這些場景電纜數(shù)量少、重量輕，不用承受過大壓力，1.5mm厚度完全夠用。

　　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.

　　這種厚度的鋁合金橋架，性價比極高，濟南本地市場價大概28-45元/米，表面經(jīng)過陽極氧化處理，鍍層厚度≥15μm，鹽霧測試≥480小時，在濟南室內(nèi)干燥環(huán)境下，使用壽命可達12-15年，而且重量輕，每米僅重2.2-2.8kg，工人安裝時不用額外借助大型設(shè)備，施工效率比鋼制橋架提升25%，特別適合室內(nèi)輕載場景。

　　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.

　　第二種，2mm厚的鋁合金橋架，屬于“中載款”，適配場景更廣泛，占濟南鋁合金橋架市場用量的35%。它的承載能力提升4kN/m，每米可承重100-120kg，比1.5mm厚的橋架強度提升60%，主要用于建筑外墻、室內(nèi)需較強承載能力的場所，比如濟南高新區(qū)產(chǎn)業(yè)園的車間設(shè)備電纜、寫字樓的空調(diào)電纜，以及沿街商鋪的戶外供電線路。

　　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.

　　濟南夏季多雨、冬季多風(fēng)，建筑外墻的橋架要承受風(fēng)雨侵蝕和一定的外力沖擊，2mm厚的鋁合金橋架，板材經(jīng)過特殊擠壓成型處理，抗變形能力更強，不易被風(fēng)吹變形，表面采用靜電噴塑或陽極氧化處理，耐腐蝕性更優(yōu)，在濟南戶外潮濕環(huán)境下，使用壽命可達10-12年，濟南本地市場價大概40-65元/米，兼顧實用性和經(jīng)濟性，是多數(shù)中載場景的。

　　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.

　　第三種，3mm厚的鋁合金橋架，屬于“重載款”，針對性解決大跨度、高承載的需求，占濟南鋁合金橋架市場用量的25%。它的承載能力可達6kN/m，每米可承重150-180kg，強度是1.5mm厚橋架的2.4倍，主要用于大跨度工廠、機場、車站、大型場館等場所，比如濟南遙墻國際機場的供電電纜、章丘大型工廠的生產(chǎn)線電纜，以及西客站周邊的市政供電線路。

　　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.

　　這類場景的橋架跨度大（多在3-6米），電纜數(shù)量多、重量大，對強度要求極高，3mm厚的鋁合金橋架，采用加厚合金板材，經(jīng)過熱處理強化，抗撓度極強，跨度6米時也不會變形，表面采用高端陽極氧化處理，耐腐蝕性和耐磨性拉滿，在濟南戶外復(fù)雜環(huán)境下，使用壽命可達15-20年，濟南本地市場價大概70-110元/米，雖然偏高，但耐用性和性有保障，避免后期頻繁更換帶來的麻煩和損失。

　　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.

　　補充一組濟南本地實用提醒，幫大家避坑：很多商家為了省錢，會用1.2mm厚的鋁合金橋架冒充1.5mm厚的，厚度不達標(biāo)，強度會降低40%以上，用不了3年就會變形、損壞，濟南朋友選購時，一定要用卡尺實測厚度，誤差不能超過±0.1mm，同時認(rèn)準(zhǔn)濟南本地正規(guī)廠家，比如濟南暢通實業(yè)、山東增利來等，這些廠家的產(chǎn)品嚴(yán)格遵循國標(biāo)生產(chǎn)，質(zhì)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.

　　總結(jié)來說，濟南鋁合金電纜橋架的厚度選擇，核心就是“按需選”，1.5mm適配室內(nèi)輕載、2mm適配中載及戶外、3mm適配重載及大跨度，遵循國標(biāo)要求，結(jié)合自己的使用場景和電纜重量，不用盲目追求厚款，也不能為了省錢選薄款。選對厚度，既能保證電纜，又能節(jié)省成本、延長使用壽命，不管是家用、商用還是工業(yè)用，只要選對了，濟南鋁合金電纜橋架就能默默守護用電，成為建筑里不可或缺的“隱形功臣”。

　　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.
