Ruukki Offers Strong, Weather-Resistant Structural Steel
03/11/2010 - Ruukki is launching Optim 960 QCW structural steel, a new grade that combines high strength and weather resistance. Optim 960 QCW is made using a direct quenching process developed by Ruukki and is suitable for applications such as containers, cranes, and booms.
Ruukki is launching Optim 960 QCW structural steel, a new grade that combines high strength and weather resistance. Optim 960 QCW is made using a direct quenching process developed by Ruukki and is suitable for applications such as containers, cranes, and booms.
“Optim 960 QCW opens up entirely new opportunities for structural design without having to compromise on structural requirements. The steel will result in lighter structures, which in turn translate into savings in the energy consumption of mobile vehicles, for example. The steel’s resistance to atmospheric corrosion can also lead to cost savings in applications where a patina finish is required,” said Ruukki Vice President Ilkka Homanen.
Ruukki’s new steel grade is also said to save on maintenance costs; it provides a good bonding surface for color coatings, which means less need for maintenance painting. Corrosion resistance develops as the steel patinates, so rust is prevented from penetrating under dents in the coating surface.
“Ruukki is licensed to make COR-TEN weather-resistant steel, which develops rust protection as it patinates. We also otherwise have long experience of making weather-resistant steel. In addition, Ruukki is meeting customer needs by launching a high-strength steel option which also features weather-resistance properties,” said Homanen.
Rautaruukki supplies metal-based components, systems and integrated systems to the construction and engineering industries. With operations in 27 countries and around 11,700 employees, the company generated net sales of approximately EUR 2.0 billion in 2009. The corporation uses the marketing name Ruukki.
