Ruukki is responding to the needs of its customers with the launch of Ruukki Optim 550 W structural steel, which combines the properties of weather-resistant steels and high-strength structural steels.

A structure made of weather-resistant steel develops a patinated surface. This means it needs no surface treatment and can withstand corrosion attack by the elements much better than conventional structural steels. The high strength of the steel can be utilised by machinery and equipment builders to lighten the tare weight of mobile machines and thus increase their payloads.

This in turn reduces overall fuel consumption. If colour coating is desired, it adheres to weather-resistant steels better than to conventional structural steels. ?These steels are ideal for use in various rolling stock applications, as well as in the lattice structures of power line pylons and in agricultural trailers, for example,? said Thomas H?rnfeldt, Senior Vice President, Ruukki.
