With years of expertise in designing, manufacturing, and supplying both octagonal and tubular steel poles, they provide solutions that combine safety, strength, and aesthetic appeal for a wide range of lighting applications.

What Are Octagonal Steel Poles?

Octagonal steel poles are designed with eight flat sides, forming a tapered, geometric profile. This shape is not only visually distinct but also provides excellent structural strength, as the angles help distribute loads evenly along the pole’s length. Octagonal poles are commonly used for urban streets, highways, parking areas, and decorative lighting projects.

These poles are available in various heights and diameters, typically ranging from 4 meters to 15 meters or more, depending on the application. The tapering design allows for stability while accommodating different light fixture sizes and weights.

The advantages of octagonal poles include enhanced aesthetic appeal, strong structural performance, and reliable wind and weather resistance. They are usually manufactured from high-quality steel and coated with galvanized, powder-coated, or paint-finished surfaces to prevent corrosion and extend service life.

What Are Tubular Steel Poles?

Tubular steel poles feature a hollow cylindrical design that provides strength while reducing material usage and overall weight. The tubular structure ensures even load distribution and makes these poles highly suitable for street lighting applications where long spans or multiple light fixtures are required.

Tubular poles are widely used for urban roads, highways, pedestrian pathways, and industrial areas. Their lightweight design simplifies transportation and installation, allowing faster setup without compromising structural integrity.

These poles are commonly made from high-grade steel and are protected with galvanization, powder coating, or specialized paint finishes to resist corrosion and harsh environmental conditions. The combination of strength, durability, and ease of handling makes tubular steel poles a preferred choice for modern street lighting projects.
