1、看机柜支撑主梁（也就是框架）结构是否扎实，直接的方法就是用手推一推，摇一摇看是否晃动的厉害。晃动的厉害的肯定质量不咋的。

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、看表面处理是否良好，主要看喷涂是否均匀，有没有毛刺、脱漆等。

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

3、看机柜内部结构是否合理，比如U立柱是否扎实，布线是否方便等。一般机柜的主要功能就是安装设备和方便布线，所以这两点也蛮重要的。

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、看脚轮和支撑脚承载能力是否强，有些机柜多推几次脚轮就坏了，那肯定质量不好。当然，如果上面3点好，就这个不好，那也可以把脚轮和支撑脚拆掉使用，那么也是个好产品。

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、就是看机柜门开启是否灵活，网孔的通风率是否满足自己需求，门锁是否好用等。

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.
