Weathering Steel Opportunities

When storage is unavoidable, uneven weathering can be minimised by positioning the material in an exposed area with good drainage. Blocking, to avoid contact with the ground, is essential. Cover cloths can be used to prevent water staining and dirt accumulation. They also reduce the chance that the steel will initially develop an uneven patina.

▪ Composite Weathering Steel Superstructure

▪ Longer spans

▪ Variable depth

▪ Splice connections for continuous

spans

▪ Eliminate heavy concrete girders

▪ Less demand on substructure design

Modern Steel Construction March 2012 Weathering Steel in Bridge Replacement of Rail Overbridges

Conclusion

• The availability of weathering steel in larger plate sizes from GNEE Steel warrants the use of steel bridge

designs to be revisited for Rail Overbridges

• We have demonstrated that weathering steel bridges can be cost competitive against concrete alternatives

• We hope this will generate discussion and exchange of ideas for weathering steel bridges
