Black poles refer to the prototype of the street lamp pole that has not been finely processed. It is a rod-shaped structure initially formed through a certain molding process, such as casting, extrusion or rolling, which provides a basis for subsequent cutting, drilling, surface treatment, and other processes.
For steel black poles, rolling is a common method. By repeatedly rolling the steel billet in a rolling mill, its shape and size are gradually changed, and finally the shape of the street light pole is formed. Rolling can produce a pole body with stable quality and high strength, and the production efficiency is high.
The height of black poles has various specifications according to their use scenarios. Generally speaking, the height of street light poles beside urban roads is about 5-12 meters. This height range can effectively illuminate the road while avoiding affecting surrounding buildings and vehicles. In some open areas such as squares or large parking lots, the height of street light poles may reach 15-20 meters to provide a wider lighting range.
We will cut and drill holes on the blank pole according to the location and number of lamps to be installed. For example, cut at the location where the lamp is installed on the top of the pole body to ensure that the lamp installation surface is flat; drill holes on the side of the pole body for installing parts such as access doors and electrical junction boxes.
