As the name suggests, diameter of the round conical poles gradually decrease from bottom to top, and have a circular section. Theese poles taper at a determined rate. This rate offen called conicity degree. The conicity degree shows the diameter reduction per meter of height and 1-1.5% /10 and 12mm/m) conicity degrees are the most common.
Round conical poles are used in projects with visual priorities. Thus, sole galvanization is not frequent for these poles and these poles are usually painted after being galvanized.
