The steel pole processing industry encompasses the fabrication of various types of light poles, including ordinary street light poles, square light poles, transmission poles, and traffic function poles. These poles serve diverse functions such as supporting traffic signals, guide signs, cameras, and advertisements. Light poles come in different shapes and sizes, with parameters such as plate thickness, dimensions, and height varying according to their intended use.
Light poles are typically categorized into conical and cylindrical shapes. These poles are crafted from hot-rolled steel plates, with Q234 being a common choice in many countries, while Q345 is preferred in the United States.
| Material | Q235, Q345 | Thickness | 3-6mm |
| Steel Coil Width | 800-1600mm | Max Length | 12m, 14m |
| Shape | Conical or cylindrical |
Pole Types
Octagonal light poles are crafted with an 8-sided steel construction and are extensively used in lighting infrastructures around the world. The manufacturing process primarily involves the precise bending of 8 edges using hydraulic press brakes, with the final edge being prepped for welding to complete the structure. These poles are generally made from mild steel, chosen for its durability and cost-effectiveness, making it ideal for widespread application in public and urban areas.
Tapered steel poles, known for their circular cross-section, are also widely recognized and used globally. They are manufactured using conical male/female molds that ensure uniformity and structural integrity. This design contributes to their superior low wind resistance, making them particularly suited for areas prone to high winds. Like the octagonal poles, these too are fabricated primarily from mild steel, which provides the necessary strength and longevity while remaining cost-effective for large-scale deployment in diverse environments.
Common specifications for tapered poles
| Height (m) | Top/bottom diameter (mm) | Steel coil thickness (mm) | Taper ratio | Flange size and row pitch (mm) | Base (mm) |
| 6 | Ø60/Ø126 | 2.75 | 11‰ | 250×250×10--180 | 180X180-Ø12 |
| 7 | Ø60/Ø137 | 3.0 | 300×300×12--210 | 210X210-Ø16 | |
| 8 | Ø60/Ø148 | 3.0 | 300×300×14--210 | 210X210-Ø16 | |
| 10 | Ø70/Ø180 | 3.75 | 350×350×16--250 | 250X250-Ø18 | |
| 12 | Ø70/Ø202 | 3.75 | 400×400×18-300 | 300X300-Ø18 |
Before production, determining the thickness of the raw materials, light pole height, top and bottom diameters, and cross-sectional shape is essential. These specifications guide the selection of the appropriate machine model for fabrication.
