Re: Use of weathering steel

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Do not use weathering steel where staining of concrete is an esthetic
consideration.  I recently made a trip to Houston and saw weathering steel
supporting overpasses. The concrete column which supported the steel had
more rust stains than white. I would tell you the location of the overpass
but I was probably lost at the time. (I10, 610 Loop, Beltway Tollway,
Southwest Freeway, etc. etc. etc.)
