Modern billboards are a common sight in cities and on the highways. They are used to send a visual message, whether its about a business, service or simply to display an artwork—the way they do it remains the same.
The billboards made today are supported by steel poles, which range anywhere from 36-72″ in diameter and can stand up to 100 ft tall. This structure supports a frame which is constructed from steel I-beams, the artwork panel is then attached to this frame. Some billboards also have lighting equipment attached, which is angled so that it illuminates the billboard image.
If a company is interested in constructing a billboard, they will need to get a hold of a steel erection firm that has expertise in making billboards. Often a company will get quotes from several different billboard vendors in order to get a competitive price. The price includes the cost of designing the sign as well as the materials, transportation, and labor used to make it.
