The success of a corten steel bridge

Although weathering steel is slightly more expensive initially than non-weathering steel, it is ultimately more economical because it does not require initial or maintenance painting. Weathering steel performs as well but not better than non-weathering steel in painted applications, so avoid requiring weathering steel in painted applications. Fabricators may prefer to use weathering steel for painted bridges, and GNEE allows substitution of weathering steel for non-weathering steel if all other material requirements are satisfied. Avoid using hybrid girders consisting of A 709 Grade 36 webs with A 709 Grade 50 flanges for painted bridges. Although these hybrids may seem economical, the cost difference of the two grades of steel is actually minimal. In contrast, A 709 Grade HPS 70W may be economical only in hybrid girders. With Grade 50W webs, use a hybrid configuration with HPS 70W tension flanges and HPS 70W compression flanges in negative moment regions. Electroslag welding, which saves a considerable amount of fabrication time and money, cannot be used with high performance steel. The use of HPS 70W steel may be restricted by:

• The fact that its stiffness is not increased over lesser grades.

• Its availability. Do not specify HPS 70W steel in a design unless availability is verified with local fabricators—for example, rolled sections are currently not available in this steel.
