from a high of 10,000 tons as is the case in the Eiffel Tower to as low as a few hundred tons. They are built to a higher standard to support the weight of the oil platforms built on top of them and because of the forces to which they are subjected. As a result, the cost to build these structures can run into the hundreds of millions. These costs are justified due to the resulting oil and gas revenues, whereas land-based towers have a much lower stream of revenue and therefore the capital costs of towers are typically much less. Timeline of world's tallest lattice tower Since end of the 19th century, tall lattice towers were built. Lattice towers have even held the absolute height record. They are among the tallest free-standing architectural structures and hold a number of national records, such as the tallest free-standing or even overall tallest structure of a country.

Electrical Pylons List of Electrical pylons above 150 m / 500 ft in height. Wind turbines Tall wind turbines supported by lattice tallest have been built almost exclusively in Germany, one of the first countries in the world to build wide spread renewable power resources. The total height includes the lattice tower and the wind turbine rotor at peak height. List of wind turbines with a lattice tower above 150 m / 500 ft in height. Chimneys/Smokestacks The majority of tall lattice chimneys in the world are located in Japan. Unlike other modern developed countries which use reinforced concrete to build tall chimneys Japan has historically used steel until recently for chimney construction.
