Few people manage outdoor billboards after they are installed.
At present, there are many types of outdoor advertising, including light box advertising, door-side print advertising, mountain-side street advertising, neon advertising, and poster advertising. Among them, the most widely used is the door advertisement, and the main component of the door advertisement is the steel frame structure. If it is just coated with protective paint, it can generally be used for 5-10 years, regardless of whether it is not more than three years.
As for how to strengthen the billboard, the most important one is the expansion bolt, and then several "foot" of the steel frame structure. This requires us to check frequently to avoid accidents that could cause injuries.
In addition, pay attention to whether the wall is firm. If the wall is loose, the tightening expansion bolt cannot fit the wall. So we pay more attention to it after installation, often check, and often maintain!
