Gerdau Corsa est un important fabricant de profilés en acier structurels et commerciaux avec un profond engagement pour la sécurité des employés et la protection de l'environnement. Ils démontrent activement cet engagement en cherchant à mettre en œuvre des solutions sûres et durables sur toute leur chaîne de production. Gerdau Corsa exploite une aciérie et un laminoir, la première dans l’État de Mexico et l'autre dans la ville de Sahagún, Hidalgo. La construction de l'usine de Sahagún City a commencé en 2012, avec l'intention de développer une installation de référence pour l'industrie sidérurgique au Mexique et en Amérique latine. D'un montant de 600 millions de dollars, il s'agit de l'investissement privé le plus important de l'histoire de l'État d'Hidalgo.

The Sahagún City plant has 250 employees who maintain the machinery and work in high and medium-voltage electric rooms. Safeguarding their lives, while they continue to work in areas containing electrical equipment central to the plant’s operation, represented a significant challenge when selecting a fire suppression system. Additionally, the fire system had to be aligned with Gerdau Corsa’s environmental protection philosophy. The new plant features integrated state-of-the-art sustainable technology which includes a preheating system and a continuous scrap-iron feed, as well as a water treatment plant. Executing this vision required the implementation of a green and sustainable fire suppression solution to safeguard employees and protect the equipment.

During the assessment process for fire suppression systems, the company discarded solutions that released inert gases such as CO2, because these systems pose considerable health hazards to workers during a discharge. Also, their installation called for modifications to the plant to maintain room integrity, which translated into increased cost and time to construct. Furthermore, in the event of an activation, these types of gaseous fire suppression systems require the evacuation and isolation of the affected area before workers can go back into the facilities, thus delaying the time required to resume plant operations. Lastly, these types of systems cannot be zoned, so their installation requires an individual system to be installed in each of the 33 areas needing protection.

Lorsque Pronamet, une société d'ingénierie mexicaine spécialisée dans la conception et la mise en œuvre de systèmes d'extinction d'incendie, a pris connaissance des difficultés de Gerdau Corsa, ils savaient, en tant qu'intégrateur certifié Victaulic Vortex™ depuis 2009, qu'un système d'extinction d'incendie hybride (double agent) serait la meilleure approche.

The Pronamet team installed a total of ten Victaulic Vortex 1500 systems to protect electrical rooms, the electrical substation, and high and medium-voltage transformers. The protected area at the plant totaled 294,000 ft3 distributed in 33 zones, including personnel control booths. The installed systems protect equipment valued at $60 million USD.

With the installation of Victaulic Vortex 1500, Gerdau Corsa guarantees operational continuity, since, in the case of activation, the recovery of the protected area would only require between one and two hours of downtime, while the complete reactivation of the fire suppression system takes only four hours, including the time needed to refill the nitrogen and water tanks.
