Hot galvanizing is a commonly used outdoor anti-corrosion galvanizing technology. The thickness of zinc layer can reach 65um. Hot galvanized cable tray can resist outdoor wind, rain and sunlight without rusting. Its span is 1.5m to 6m. If outdoor columns are used for fixing, the general spacing is 6m. The safety load of hot galvanized cable tray is related to the span, material and height of the tray. Next, we will introduce the processing technology of hot galvanized cable tray:

1、使用寿命长，生产工业化程度高，质量稳定。因此广泛应用于受大气腐蚀严重、维护困难的室外环境。

1. Long service life, high degree of industrialization and stable quality. Therefore, it is widely used in outdoor environment with severe atmospheric corrosion and difficult maintenance.

2、过程不同。热镀锌电缆桥架采用冷轧钢制作，除锈后浸入600的高温锌液中，使桥架表面附着锌层。5mm薄板厚度不小于65m，5mm及以上厚度不小于86m m，相当于给整个桥架贴上了一层保护膜，所以其热浸镀锌具有优异的耐腐蚀性能。对于化工厂、沿海等腐蚀性场所，维护量减少，成本降低。

2. The process is different. The hot-dip galvanized cable tray is made of cold rolled steel. After rust removal, it is immersed in 600 high temperature zinc solution to make the tray surface adhere to zinc layer. The thickness of 5mm thin plate shall not be less than 65m, and the thickness of 5mm and above shall not be less than 86m, which is equivalent to pasting a protective film on the whole bridge, so its hot-dip galvanizing has excellent corrosion resistance. For corrosive sites such as chemical plants and coastal areas, the maintenance amount and cost are reduced.

3、热镀锌板电缆桥架采用热镀锌板(锌层只有25m)，后期没有防腐处理。梯型电缆桥架与热镀锌电缆桥架相比，外形美观，但未进行防腐处理。所以不能在室外、化工厂、海边等有腐蚀性的地方使用。并不是所有的热镀锌都是热镀锌板和电缆桥架，这取决于他的加工工艺。

3. Hot galvanized sheet cable tray is made of hot galvanized sheet (the zinc layer is only 25m), and there is no anti-corrosion treatment in the later stage. Compared with hot-dip galvanized cable tray, ladder type cable tray has beautiful appearance, but no anti-corrosion treatment is carried out. Therefore, it cannot be used outdoors, in chemical plants, at seaside and other corrosive places. Not all hot-dip galvanizing is hot-dip galvanized sheet and cable tray, which depends on his processing technology.

4、热镀锌电缆桥架有锌层保护，但不生锈是因为锌在干燥空气中不易发生变化，但在潮湿空气中，可在表面形成一层致密的碱式碳酸锌膜，可保护内部不受腐蚀。而且，当由于某种原因，开槽的电缆桥架损坏了涂层，露出了一个小钢底座时，锌和钢底座形成了一个微型电池，使钢底座成为阴极，受到保护。所以对于锌层厚度为65um的电缆桥架，使用30年不生锈，不易损坏。大大延长了桥架使用寿命。

4. Hot dip galvanized cable tray is protected by zinc layer, but it does not rust because zinc is not easy to change in dry air, but a dense alkaline zinc carbonate film can be formed on the surface in humid air, which can protect the interior from corrosion. Moreover, when the grooved cable tray damaged the coating and exposed a small steel base for some reason, the zinc and steel base formed a miniature battery, making the steel base a cathode and protected. Therefore, the cable tray with a zinc layer thickness of 65um will not rust or be damaged after 30 years of use. The service life of the cable tray is greatly extended.
