SESSION 2.4 Weathering Steel

WEATHERING STEEL Summary Weathering steel bridges should not be considered 100% maintenance free. Owners should be aware of the issues,especially with bridges in harsh environments. We will continue to use weathering steel,but will monitor performance more carefully. Moore Drive - coupon evaluation is ongoing.SSAB Weathering steel for structures and steel bridges - SSABSSAB Weathering steel has a much smaller environmental footprint than non-weathering steels.Emissions and pollution to the structures surrounding,caused by painting and stripping before re-painting,can be avoided when used in unpainted condition.A steel bridge made of SSAB Weathering steel is 100% recyclable at the end of its service life.SSAB high strength weathering steel is optimized for low SSAB is now introducing high-strength weathering steel grades 420 ML and 460 ML.When you specify these high-strength grades in bridge construction or to build rolling stock or other structures,you can use less steel yet maintain high strength.Upgrading to these higher-strength steels gives you superior weldability,lower life cycle costs and
