The ATRIO Towers in Bogota: The first high-rise venture for ArcelorMittal in South America
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.
3900 tonnes of sections from ArcelorMittal plants in Luxembourg and Spain
Constructing a high-rise building in a seismic zone and in a country where most constructions are made of concrete was a sizable challenge taken up by the teams involved in this project.
Designed by the architecture firms Rogers Stirk Harbour + Partners and El Equipo Mazzanti, the ATRIO Towers feature impressive column elements and facade trusses built to resist seismic activity and to improve the torsional behaviour of the structure - a breakthrough for local architecture and structural design.
To comply with the design and its technical requirements, ArcelorMittal International provided 3900 tonnes of steel sections, including 400 tonnes in HISTAR® grade (ASTM A913), produced by ArcelorMittal Europe – Long Products in Differdange.
Customers 100% convinced by the steel solution
ArcelorMittal Europe – Long Products’ association with the project (through our technical assistance department) began in 2013 with AECOM consultants and subsequently with ARUP engineering.
A number of reasons were behind the choice to work with ArcelorMittal:
• HISTAR® steel offers the exact weldability properties that the client needed and does not require preheating.
• We offer the widest range of sizes among steel producers.
• We can provide long-length sections as well as cut-to-length sections.
• The project required steel made with at least 50% recycled material and our sections are 100% scrap-based.
Apart from its mechanical properties, the use of steel helped to improve the design of the tower. Thanks to the jumbo steel sections embedded in concrete, column size was reduced resulting in elegant slender composite columns with sophisticated diagonal lines in the facade.
Breathing new life into the city centre
This development provides a boost to the Centro Internacional area, the city’s former business district, by bringing new business, tourism, public transportation, and culture to the area. The construction of the North Tower, measuring 200 metres (44 floors), is the first phase of the project. 50 000 m² of office space, 4 600 m² of public services, and 1800 m² of retail space are available.
The high quality of our products, the service provided, and the efficient cooperation between the teams at ArcelorMittal International and ArcelorMittal Europe – Long Products were important factors in our successful participation in this project.
The construction of the ATRIO North Tower started in 2015 and is now complete. It is one of the first major steel high-rise buildings in South America, and it certainly won’t be the last.
An award-winning tower
ATRIO North Tower attained LEED GOLD certification and has won several awards, including:
• Council on Tall Buildings and Urban Habitat (CTBUH) 2021 Awards in the following categories: Best Tall Building 200-299 Metres 2021 Award of Excellence, Best Tall Office Building 2021 Award of Excellence, and Structural Engineering 2021 Award of Excellence.
• ICCA ACESCO 2019 Prize in the Building category.

Our steel found in mint condition in 1904 house
In the city of Bonn in Germany, steel beams produced by ArcelorMittal's Differdange mill were recently discovered in perfect condition in a centenary house during a remodelling project.
First-class quality after almost 120 years
Blending in with the white interior design of the house, the beams could almost go unnoticed. This was exactly the case until the owner, Paul Udo Hanus, decided to renovate. He was astonished by his discovery: 'DIFFERDINGEN NP 12' stood out on the massive steel beams that were "in perfect condition".
Wondering where the beams could have been manufactured, Paul’s internet search led him to ArcelorMittal. He thought it would be a nice idea to contact the company. In an email, he highlights the perfect condition of the steel beams and pays compliment to the colleagues and employees of 1904 and to ArcelorMittal for the first-class quality that is still maintained today. Steel beams were manufactured under difficult, industrial conditions at that time, which is why the long durability is even more gratifying.
Our Differdange mill today
Today, ArcelorMittal Europe – Long Products’ Differdange mill still produces similar beams. Thanks to several modernisation programmes over the years, today the mill can produce the heaviest beam blanks and the longest and heaviest beams in the world.
Moreover, the QST (Quenching and Self-Tempering) process is being used to produce a new generation of HISTAR® beams of exceptionally high quality.
Thanks to their high yield strength, outstanding robustness, and very good welding properties, they have made Differdange famous worldwide. They are used in the construction of high-rise buildings all over the world and will probably last at least 120 years - just like their ‘great-grandfathers’ in Bonn.

Performance and capacity of composite mega columns with encased hot rolled steel sections
The optimisation of construction materials, including the size reduction of structural system components, is fundamental in the modern construction of high-rise buildings. Composite structural components consisting of concrete and steel are a sustainable solution. This research paper investigates the use of composite mega columns, with hot-rolled steel sections fixed in concrete, as vertical structural systems. Tests were conducted to explore maximum capacity, displacements, stress distribution, ductility, and stiffness, culminating in suggested simplified design methods based on European, Chinese, and American codes.
Paper abstract
“Steel reinforced concrete (SRC) columns are widely used in high-rise buildings, since they provide larger bearing capacity and better ductility than traditional reinforced concrete (RC) columns. This type of structural system is not currently explicitly addressed in the actual design codes. The paper aims at presenting the behaviour of a new configuration of mega columns - isolated steel reinforced concrete (ISRC) columns. A two-phase test was conducted on scaled ISRC columns designed based on a typical mega column of a super high-rise building. Phase 1 of the study includes six 1/4-scaled ISRC columns under static loads: every two of the specimens are loaded statically with the eccentricity ratio of 0, 10%, and 15%, respectively. Phase 2 of the study includes four 1/6-scaled ISRC columns under quasi-static loads: every two of the specimens were loaded under simulated seismic loads with the equivalent eccentricity ratios of 10% and 15%, respectively. A finite element analysis (FEA) was conducted as a supplement to the physical tests to provide a deeper insight into the behaviour of “mega columns”. An extended Plastic Distribution Method is defined to evaluate the capacity of the specimens. The method is based on simplifications similar to those proposed in EC4 [1]. The scope of this latter standard is limited to the consideration of one single steel profile. The method is validated by comparisons with experimental and with numerical simulation results using advanced finite element programs, showing a good accuracy in results.”

DIBt technical approval enables SCHRAG to make full use of Magnelis®
Since 2014, ArcelorMittal has been working with the SCHRAG Group to publicise the benefits of Magnelis® in the German and eastern European markets. That cooperation has led to Magnelis® being recognised as an exceptional metallic coating which provides a breakthrough in corrosion protection. In September 2019, the Deutsches Institut für Bautechnik (DIBt) granted Magnelis® a Technical National Approval. This approval recognises that Magnelis® resists corrosion for more than 15 years and allows it to be specified for construction applications in Germany and other markets which rely on DIBt standards. For SCHRAG, it means that Magnelis® can be utilised with confidence in the company’s thin-walled cold-formed components, even when they are deployed in highly corrosive atmospheres.
Steel's role
Steel plays a substantial role in SCHRAG’s tailor-made solutions for roofing and cladding which are used in industrial and commercial construction. ArcelorMittal supplies a range of metallic coated and painted coils to SCHRAG. These products are typically utilised to create bent profiles which are used as lightweight parts for roofs and walls. Applications include purlins, transoms, skylight substructures, and moulded parts.
Durability of Magnelis® stands out
"The outstanding properties of Magnelis®, documented in the DIBt approval, have enabled SCHRAG to make full use of Magnelis® in many applications,” says Gunnar Koelsch, head of purchasing at SCHRAG. “For example, Magnelis® ZM310 is the only zinc-magnesium coating which remains durable for more than 15 years according to DIBt. And the approval covers constructions in zones with a corrosivity rating of C4 under the European norm ISO 12944-2. This is unique.”
Magnelis® effectively protects surfaces against corrosion in two ways: as a barrier and as cathodic protection. It also offers excellent protection on cut edges. In these areas, the coating reforms to ensure full protection for the steel substrate. After checking the self-healing effect of Magnelis® on cut edges, DIBt concluded that the coating (minimum weight of ZM310) can be utilised with uncoated edges of up to 6.0 mm. The uncoated edges should not have an aesthetic function. This is the only German technical approval for a metallic coating which includes uncoated edges up to a thickness of 6 mm.
Strong partnership relies on open communication
One of SCHRAG’s goals is to act as a problem solver for its customers. Common projects and long-term partnerships are essential for this as Gunnar Koelsch explains: “A real partnership requires long-term cooperation, commercial and technical transparency. We have found such a partnership with ArcelorMittal.”
The very good partnership between the two companies covers subjects ranging from classic sales topics to joint projects. Both appreciate the open communication, even during negotiations. “This is particularly evident in challenging times such as those we face today,” says Mechthild Janischowsky, market segment manager at ArcelorMittal Commercial Germany. “Models have been developed which offer viable solutions for both partners. This has only been possible through the mutual trust we have developed after decades of working together.”
About SCHRAG
Founded in 1892, SCHRAG began as a small business which produced enamelled, tinned, and galvanised products. Today the company is led by the fourth generation of the family and manufactures lightweight metal solutions for roofs and facades. The SCHRAG Group employs almost 500 people at 16 locations in Austria, Czechia, Germany, Poland, Slovakia, and Switzerland.
