The ATRIO Towers in Bogota: The first high-rise venture for ArcelorMittal in South America18 March 2021
ATRIO is an impressive mixed-use project located in the centre of Bogota, Colombia. Composed of two towers, North and South, it will offer 250 000 m² of office space and 10 000 m² of public space at ground level. It is the first high-rise project for ArcelorMittal in South America. 90% of the steel sections for the construction of the North tower were provided by ArcelorMittal.Project News

A wide range of the highest quality
The mechanical characteristics of ArcelorMittal's sections are improved by precise control of the temperature during the rolling process.
Steels, produced using thermomechanical rolling (delivery condition M), feature improved toughness values thanks to a lower carbon equivalent and a fine microstructure when compared with normalised steels. With regard to their technological properties, the thermomechanically rolled steels have good cold forming properties. Similar to conventional structural steels, they can be flame straightened provided specific maximum temperatures are not exceeded.
In case stress relieving is considered for reducing residual stresses, the usual parameters concerning temperature range and heating time according to the rules of practice must be applied. Hot forming, which is uncommon for the fabrication of sections, must not be performed in accordance with EN 10025:2004.
The steels are typically delivered with an Si content ranging between 0.14% and 0.25% and are as such capable of forming a zinc layer during hot-dip galvanisation.
As the phosphorus content of these steels is usually lower than 0.035%, this does not have any influence on the final thickness of the coating in the considered Si range.
