What is the difference between conical steel poles and polygonal steel poles?

Both tapered and polygonal tubular steel poles are fabricated by rolling steel plates; however, tapered poles involve more extensive welding processes, whereas polygonal poles feature a simpler manufacturing process and lower production costs. Generally, for voltage levels below 220 kV, the polygonal design is well-suited for current projects, offering a simple manufacturing process, low costs, and a short production lead time.
