A LOW-COST MAINTENANCE-FREE STRUCTURAL STEEL FOR HIGHWAY APPLICATIONS

HIGHWAY ENGINEERS AND LANDSCAPE ARCHITECTS HAVE INDICATED A NEED FOR A STRUCTURAL MATERIAL THAT IS LOW IN INITIAL COST AND REQUIRES A MINIMUM EXPENDITURE OF MONEY AND LABOR FOR MAINTENANCE. SUCH A PRODUCT IS REQUIRED FOR USE IN ROADSIDE REST AREA BUILDINGS, HIGHWAY GUARDRAILS, MEDIAN BARRIERS, SIGNPOSTS AND STRUCTURES, LIGHTING STANDARDS, SNOW FENCES, BRIDGES, AND UTILITY POLES AND TOWERS. THERE IS ALSO A DESIRE IN SOME INSTANCES TO REDUCE THE AMOUNT OF LIGHT- REFLECTIVE MATERIALS EMPLOYED IN HIGHWAY STRUCTURES AND THUS MINIMIZE DISTRACTION FROM THE NATURAL SCENERY. THE USE OF UNPAINTED HIGH-STRENGTH LOW-ALLOY STEEL CONTAINING CERTAIN ALLOYING ELEMENTS TO IMPROVE ATMOSPHERIC CORROSION RESISTANCE APPEARS TO FULFILL THIS NEED. THE SUPERIOR MECHANICAL PROPERTIES AND ENHANCED RESISTANCE TO ATMOSPHERIC CORROSION OF ONE OF THESE STEELS IN VARIOUS ENVIRONMENTS ARE DESCRIBED. EXAMPLES ARE GIVEN ILLUSTRATING THE CURRENT USE OF THIS STEEL IN SUCH APPLICATIONS AS TRANSMISSION TOWERS, LARGE BUILDINGS, LIGHT STANDARDS, AND BRIDGES. /AUTHOR/
