What is the difference between conical steel poles and polygonal steel poles? Which one is more suitable for our project?

Tapered poles require more welding, while polygonal poles have simpler manufacturing and lower costs. For voltage levels below 220 kV, polygonal designs are suitable, offering simplicity, low costs, and quick production.

Can your steel poles be used in coastal areas with high salt spray?

Our poles are suitable for coastal areas with high salt-spray; we offer custom designs with specific materials and hot-dip galvanizing for corrosion resistance.
