Made of rolled steel, it retains the natural state of the raw material and requires subsequent processing before use. It is suitable as the base material for various types of light poles, flag poles, and communication poles.
They are available in a variety of shapes, including round, square, hexagonal, and octagonal, with wall thicknesses and heights designed to suit different scenarios, typically ranging from 3 to 12 meters.

In the light pole manufacturing process, black poles are semi-finished poles that have undergone basic forming but have not yet undergone surface treatment or component assembly. They comprise the fundamental structure of the light pole. The basic structural shapes of a light pole, such as round, square, hexagonal, and octagonal, are already present in black poles, they lack aesthetic and anti-corrosion treatments and have a rough surface. Usually constructed from steel, they go through procedures like cutting, bending, welding, and straightening to guarantee structural strength appropriate for later use. The performance of the final product is directly impacted by the quality of the raw material.
Dimensional accuracy and weld quality are tightly regulated by Phoebus. Before they become the assembly-ready light pole, they must undergo additional surface treatments like hot-dip galvanizing and powder coating, as well as machining operations like drilling and tapping.
Fit for producers of street lights. To meet various component installation requirements, Black Poles can undergo precision machining techniques like drilling and tapping in addition to surface treatments like galvanizing and powder coating.
Fit for small towns and rural areas. They can be used for small-scale lighting projects with a straightforward anti-corrosion treatment and small size adjustments.
It is also appropriate for short-term processing zones in major infrastructure projects. Black Poles can be cut and straightened on-site for large-scale light pole requirements in parks, roads, and other locations. This ensures compatibility with on-site installation schedules and reduces the transportation and processing cycle.
