1、看機柜支撐主梁（也就是框架）結構是否扎實，直接的方法就是用手推一推，搖一搖看是否晃動的厲害?；蝿拥膮柡Φ目隙ㄙ|量不咋的。

1. The direct way to check whether the main beam (i.e. frame) supporting the cabinet is solid is to push and shake it by hand to see if it shakes severely. The shaking is definitely not good quality.

2、看表面處理是否良好，主要看噴涂是否均勻，有沒有毛刺、脫漆等。

2. Check if the surface treatment is good, mainly to see if the spraying is uniform, whether there are burrs, paint peeling, etc.

3、看機柜內部結構是否合理，比如U立柱是否扎實，布線是否方便等。一般機柜的主要功能就是安裝設備和方便布線，所以這兩點也蠻重要的。

3. Check if the internal structure of the cabinet is reasonable, such as whether the U-pillar is solid and whether wiring is convenient. The main function of a general cabinet is to install equipment and facilitate wiring, so these two points are also quite important.

4、看腳輪和支撐腳承載能力是否強，有些機柜多推幾次腳輪就壞了，那肯定質量不好。當然，如果上面3點好，就這個不好，那也可以把腳輪和支撐腳拆掉使用，那么也是個好產品。

4. Check if the load-bearing capacity of the casters and support feet is strong. Some cabinets may break after pushing the casters a few more times, so the quality is definitely not good. Of course, if the above three points are good, but this one is not good, you can also remove the casters and support feet for use, which is also a good product.

5、非常后就是看機柜門開啟是否靈活，網孔的通風率是否滿足自己需求，門鎖是否好用等。

5. Finally, it is important to check whether the cabinet door can be opened flexibly, whether the ventilation rate of the mesh meets one's needs, and whether the door lock is easy to use.
