Zhuhai Advertising Billboard Safety Inspection and Certification Unit, Third-party Outdoor Billboard Inspection Agency

Billboards are predominantly made of steel structures, situated on the roofs of existing buildings, which not only increase the roof's load but also require connection with the original roof structure. In the past, there were no design or construction specifications for this, and advertising companies lacked knowledge in architectural structures, leading to incomplete consideration of loads in design, improper construction measures, poor construction quality. Coupled with harsh outdoor conditions, over time, the billboards themselves corrode and weld seams crack, posing safety hazards. Therefore, the quality inspection, safety, and safety monitoring of billboards have become issues that must be taken seriously.

Billboards have long been a traditional advertising medium, cherished by advertisers for their cost-effectiveness, ease of installation, and impressive impact. To enhance their ability to convey information to the public, billboards are often placed atop tall buildings, in bustling commercial districts, along major thoroughfares and corridors, and on the walls of storefronts. These locations are typically in or near densely populated areas, thus demanding higher safety standards when setting up outdoor billboards.
