Innovative solutions for steel lattice towers
9 December 2020The increase in renewable energies and the progress in telecommunication technologies (e.g. G5) require the construction of new and/or the reinforcement of existing transmission lines and telecommunication towers.The European Network of Transmission System Operators for Electricity (ENTSO-E) expect 18 000 kilometres of new transmission lines to be constructed in Europe by 2035 to cover the demand of renewable energies.

Innovative solutions for steel lattice towers
Meeting the new standards
The increase in renewable energies and the progress in telecommunication technologies (e.g. G5) require the construction of new and/or the reinforcement of existing transmission lines and telecommunication towers.
The European Network of Transmission System Operators for Electricity (ENTSO-E) expect 18 000 kilometres of new transmission lines to be constructed in Europe by 2035 to cover the demand of renewable energies.
Weight reduction using S460
Steel lattice towers made of fully recyclable hot rolled angle profiles are a typical solution for transmission and telecommunication towers.
The use of high strength steel (e.g. S460) in steel lattice towers reduces the weight of standardised towers up to 20% compared to normal steel grades (e.g. S355), leading to lighter structures which are easier and faster to erect.
Innovative solutions
The reinforcement of existing steel lattice towers with carbon fibre reinforced polymer (CFRP) strips increases the resistance of the main bearing elements by 50% and allows a quick and easy upgrade of the towers to higher voltage and bigger G5-antennas.

HISTAR® 460 makes a grand entrance in Central America
Due to political and economic issues, as well as a concrete-oriented culture, steel is not a preferred solution in Central America. However, the trend may soon reverse thanks to the first project in the region involving HISTAR®. Beams produced by ArcelorMittal Europe – Long Products’ Differdange mill were used to build a new bridge in Tegucigalpa, the capital of Honduras.
HISTAR®: an efficient and cost-effective solution for bridges
The new bridge on Fuerzas Armadas Boulevard in Tegucigalpa is now an advantage for the inhabitants of the area, giving more fluidity to the traffic and allowing people living in the area to leave in about 5 minutes – contrary to the 30 minutes it used to take.
HISTAR® 460 / A913 grade 65 was selected for this project thanks to its many advantages:
- Weight savings due to higher resistance.
- Better and more efficient weldability. Pre-heating can even be reduced or eliminated in some cases.
- Minimum impact through a slender solution and fast erection (compared to a concrete bridge).
- Savings (thanks to smaller lifting equipment, smaller consumption of electrodes for welding, etc.).
Construction of the bridge started in May 2018 and ended in July 2019 with a 100-metre-long structure made with HISTAR® girders.
A successful joint task force
A partnership between ArcelorMittal International and SOGESA (a Honduran local steel distributor) was capable of bringing the first HISTAR® 460 / A913 Grade 65 solution to the region. The project, named ‘Paso a desnivel bulevar Fuerzas Armadas-Metromall’, included building a new bridge along the road connecting two important points of the Honduran capital as part of a bundle of measures aimed at reducing traffic problems that had been hampering the city for a long time.
The alliance between ArcelorMittal International and SOGESA took steps such as promoting A913 to local design companies and steel fabricators, which set the stage for the high strength hot rolled steel solution to succeed. In addition, they managed to get the final decision-takers (Tegucigalpa City Hall) on board after a fruitful round of discussions on how a steel solution can be effective in infrastructure projects, showing them the benefits of a HISTAR® solution.
Developing our presence in Central America
In the past two years, ArcelorMittal Europe – Long Products’ beams were used to build two bridges in Tegucigalpa:
- Via Rapida bridge
- Boulevard Kuwait de la Vega bridge

Useful information
MoreA 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.
