Where was the big billboard you are holding made? To make a double-column light box billboard that is 12 meters high and 2.5 meters wide, how deep and how deep should the foundation be?
It is called an outdoor billboard. It is subdivided into roadside billboards, high-rise billboards (commonly known as anti-aircraft guns), light boxes, neon billboards, and LED billboards. It can range from a few meters in length and width to more than ten or tens of meters.
This depends on the local maximum wind force, wind resistance, light box material, and self-weight. It can be calculated based on many factors. Detailed dimensions, foundation soil quality, local climate and other information need to be provided. Blindly borrowing may be too big (wasteful) or too small (unsafe)
