The quality of the railing and the frame of the handrail, as well as the pillars and frame of the handrail, are relatively low. Some large and conventional factories use angle steel and round steel, but the angle steel and round steel in different parts must also be different. .

The quality of the strip rail track is directly affected by the different specifications of the wire (wire), diameter, and strength of the wire. Welding directly affects the quality of the grid, and the selection of the optical disc should be made by a legitimate manufacturer of the optical disc. The completed optical cable is removed from the strip; The second is the process of welding or weaving grids. This mainly depends on the operational ability and capability between technicians and production machines. Usually, a good railing is welded or assembled at every point. Everything is fine. Some conventional fence net production equipment is produced by automatic welding machines, while small factories use manual welding, which is often difficult to maintain.

3. The spraying process is general protection for railings and lawns. It is also important to pay attention to the uniformity of spray and the quality of paint in the comprehensive net protection. Thirdly, the spraying process and advanced equipment level should be managed. For a long time, due to the lack of effective protection for sculptures and surrounding vegetation, some citizens have taken shortcuts to avoid problems or management personnel have not paid attention to green mountain climbing around sculptures (mainly for children), which has led to green vegetation around sculptures. Serious damage has affected the appearance, while climbing and tracking have brought many hidden dangers. The installation of railings recalls the lawn and effectively prevents uncivilized behavior by citizens, maintains the effect of the landscape, and also reflects refined management.
