Stainless Structurals America is the only producer in the western hemisphere of stainless steel structural shapes and profiles. We stock and produce a vast array of wide flange beams used in bridge girders along with channels, angles, tees, tube and more.
Due to the harsh winter conditions in Minnesota, with long winters and extensive use of road salt, the Minnesota Transport Department chose stainless steel rebar as the best alternative for rebar for this bridge.
Use of stainless steel and stainless-clad steel for bridge deck construction ensures a long life with low maintenance costs, providing a more sustainable solution.
As we can see from the illustration, Stainless Steel Material Highway Bridge Road has many fascinating aspects to explore.
The original bridge was built primarily with concrete and structural steel reinforcement and as a result of operating in a marine environment where de-icing salts were employed during the winter months, the bridge sufered from corrosion of the reinforcing materials.
Stainless steel, especially duplex stainless steel, offers an extremely attractive way of providing structural integrity over unlimited time, thanks to their high strength and their corrosion resistance that meets all climates and weather conditions. The extra cost over a cheap short-term solution is less than 10% when used in the critical areas.
An economical stainless steel described in ASTM A1010 represents an engineering material that meets the strength and impact toughness requirements of the most commonly used ASTM A709 bridge steels.(1,2) ASTM A1010 steel overcomes the corrosion limitations of conventional weathering grades, ...
Bridge engineers are increasingly exploiting the unique characteristics of modern austenitic and duplex stainless steel alloy families to solve a range of challenges associated with bridges and highways. Each family is defined by its microstructure (i.e.
As we can see from the illustration, Stainless Steel Material Highway Bridge Road has many fascinating aspects to explore.
Stainless steel does not only have to be perceived as a premium material, but it can bring significant savings in overall lifecycle costs. In fact, based on a study conducted by Arup, lean duplex stainless steel in a composite steel-concrete bridge offered the lowest LCC for bridges over minor or major roads, marine and railway bridges.
