Street Light Pole Production Line: uncoiling, leveling, bending, and welding

The specific process points of the street light pole production line can be roughly divided into the following:

- Cutting the steel plate to the appropriate size.

- Bending metal materials into tube shapes.

- Use seam welding to merge cylindrical gaps and weld flanges, etc.

- Straightening (deformation after welding) and bending (auxiliary mechanical straight pipe is not needed).

- Surface treatment by grinder.

- Surface painting or electroplating through electrostatic spraying production line.

- Equipped with electrical appliances before leaving the factory.

Street Light Pole Production Line

Generally, street light poles are made of high-quality low-carbon steel. The upper and lower caliber and wall thickness of the light pole are configured according to customer requirements. The light pole has a flange at the bottom and is installed on the foundation through anchor bolts. The production of street light poles mainly includes: uncoiling, leveling, plate bending, welding, straightening, pipe bending, grinding and galvanizing, etc.

1. Uncoiling and leveling

Sheet Metal Light Pole Production Line Uncoiling

The raw steel coils for street light poles need to be cut using uncoiling lines. The decoiler line mainly includes decoiler, side guide device, leveling machine, shearing equipment, code row, electrical system, etc.

Sheet Metal Light Pole Production Line Cutting

We first unroll the steel coil, and then the cutting equipment cuts the steel coil into the required size. Finally, it is sent to the leveling machine for leveling through the automatic feeder.


2. Large-scale bending process

The second step is the bending process. We recommend using a heavy-duty tandem press brake for processing. Whether it is a hexagonal light pole or an arc-shaped light pole, as long as you choose the appropriate punch and die, the SC tandem press brake machine can complete the processing.

3. Automatic welding

There will be gaps after the steel plate is bent. At this time, you need to use a welding machine to weld the bent steel plate. The lamp pole welding method is automatic submerged arc welding.


This equipment adopts automatic welding and automatic flux recovery. The welds are uniform, continuous and beautiful. Strong penetration, joint welding and forming in one step. High welding efficiency and reliable welding. The surface is smooth and has no obvious pores, welding nodules, undercuts and other welding defects.

4. Straightening and bending pipes

In order to prevent the light pole from deforming after welding, it needs to be re-aligned. However, this does not necessarily require machinery and can also be done manually. The specific needs are determined based on the budget. If you need a bent light pole, you need a pipe bending machine. Likewise, there are different machines to choose from. If the light pole does not need to be bent, it does not need to be configured.


5. Surface treatment

The anti-corrosion treatment of steel poles adopts hot-dip galvanizing inside and outside. The galvanizing process includes pickling, hot-dip galvanizing, water washing, phosphating, passivation and other processes. The surface of the galvanized layer is smooth and beautiful. The luster is consistent, and there are no defects such as wrinkles, runoff, zinc tumors, peeling, spots, yin and yang surfaces, etc.


After hot-dip galvanizing, the lamp pole is classically sprayed (color optional). Before spraying, it is frosted to increase adhesion. The curing time and temperature are strictly controlled during the spraying process to ensure that the plastic layer is uniform, smooth and free of pores.
