This is a list of tallest freestanding steel structures in the world past and present. To be a freestanding steel structure it must not be supported by guy wires, the list therefore does not include
guyed mast
A guyed mast or guyed tower is a tall thin vertical structure that depends on guy lines (diagonal tensioned cables attached to the ground) for stability. The mast itself has the compressive strength to support its own weight, but does not ha ...
s and the main vertical and lateral structural elements and floor systems in the case of buildings, are constructed from steel. This type of construction is a rarity today as most tall buildings are built with a composite structure featuring a reinforced concrete core.
Oil platforms built using rigid steel jackets, such as the
Bullwinkle (oil platform)
Bullwinkle was a tall, pile-supported fixed steel oil platform in the Gulf of Mexico. Installed in 1988, the total weight of the platform was 77,000 tons, of which the steel jacket comprises 49,375 tones. At the time of its construction it was t ...
, are included and ranked as the local medium(water) does not provide any horizontal support. In fact they are over engineered specifically to resist water forces them rather than modulate them as compliant towers are designed to do.
Demolished structures and structures under construction are also included but not ranked.
Steel Structures (above 275 m / 900 ft in height)
indicates a structures no longer standing.
indicates a structure built in water.
* For all structures the pinnacle height is given meaning it includes both spires and antennas as long as they are built of steel.
