Types of lighting poles: conical, octagonal, straight, square, and decorative. Which one do you choose?

Last updated: October 20, 2026

Metal lighting poles come in five main types, classified by cross-section: the circular conical pole, the most common for streets; the octagonal conical pole for high-rise buildings; the straight pole for gardens and walkways; the square pole for facades and modern complexes; and the decorative pole for projects where aesthetics are important. The choice depends on the pole's height, the weight of the light fixtures, the installation location, and the desired design.

What is a lamppost made of?

Before comparing the types, it is helpful to know the parts of the column, as they are similar in all forms:

• Column body: It is usually formed from sheet metal that is bent and welded longitudinally, or from a ready-made pipe in straight columns.
• The arm: The spotlight is held away from the pole above the road, and may be straight, slanted, curved, or decorative, or there may be no arm and the spotlight is mounted on top of the pole.
• Baseboard: A thick plate welded to the bottom of the column with triangular supports transfers the load to the mounting bolts.
• Maintenance opening: A small door at the bottom of the column to access the electrical connections.
• Earth nails: It is poured into the concrete base and the column is fixed to it.

circular conical column

Its body is circular, gradually narrowing from bottom to top. This shape is geometrically logical, because the torque caused by the weight of the searchlight and wind pressure is greatest at the base and decreases as we go up, so there is more metal where the column needs it.

• Features: Appropriate weight for its strength, clean appearance, and equal wind resistance from all directions.
• Usage: Main and secondary streets, complex entrances, and parking areas.
• Example from the calculator: An 8-meter pole with a top diameter of 60 mm, a bottom diameter of 148 mm, and a thickness of 3 mm, weighing approximately 85 kg with one arm, as in Explanation of the street light calculator.

octagonal conical column

Its cross-section is octagonal and tapers upwards like a cone. The bent ribs increase the rigidity of the sheet metal, allowing the column to withstand greater loads with a similar thickness.

• Features: High rigidity, suitable for carrying more than one flashlight or multiple arms.
• Usage: High elevations, squares, large intersections, and stadiums.
• note: Its appearance is more artificial than a circular cone.

straight pipe

Its diameter is constant from bottom to top, and it is made from prefabricated pipes with a base plate. It is the simplest to manufacture.

• Features: Economical and quick to supply, suitable for low altitudes.
• Usage: Gardens, walkways, parking areas for houses and mosques, and rest areas.
• note: As the height increases, a fixed diameter becomes too heavy or insufficient, making a conical shape more suitable.

square column

Its cross-section is square with sharp angles, and it may be straight or slightly tapered. It gives a modern look that complements glass facades and straight lines.

• Usage: Commercial facades, modern residential complexes, and architectural corridors.
• note: Its wind resistance varies depending on the direction of the wind, and care needs to be taken when painting the corners.

decorative columns

Modern or classic designs with decorative arms and distinctive heads, often powder-coated in specific colors. Used where appearance is an integral part of the architectural design.

• Usage: Public parks, hotels, resorts, waterfronts, and luxury projects.
• note: The heights are often lower, and the cost is higher due to the shaping and finishing.

A quick comparison between types of lighting poles

How do you choose the right type for your site?

1. Start rising: The height is determined by the width of the road and the type of spotlight, as explained in the article. Height of the light pole and the distance between the poles.
2. Then pregnancy: The number of spotlights, their weight and size, and whether cameras or panels will be added.
3. Then the environment: Exposed and coastal sites require hot-dip galvanizing; see article for details. The difference between hot-dip galvanizing and electro-galvanizing This will be helpful.
4. Finally, appearance: If the project is architectural, choose the square or decorative one with powder coating over the galvanization.
