Frequently asked questions

What is the most common tower type in the US?

Self-supporting tower (code TOWER) is the most common registered structure type with 76,075 of 196,742 registrations.

What type are the tallest towers?

Guyed towers (GTOWER) hold the height records — the tallest reaches 625 m. Guy wires carry the lateral loads, which is the only economical way to ~600 m.
