What distinguishes conical from polygonal steel poles?

Tapered poles need more welding; polygonal are simpler and cheaper. For <220kV, polygonal is best for simplicity, cost, lead time.

Are your steel poles suitable for coastal areas with high salt spray?

Our poles are ideal for coastal areas with high salt spray. We provide custom designs, material selection, and anti-corrosion processes for these environments.
