Tennessee decided on a strong design. The strongest steels. And an equally strong paint system. Oncor* M50s. Improved appearance was the criterion for the Pennington Bend Bridge, Nashville, Ten nessee. So the Tennessee Highway Department chose a combination of three high-strength steels. Which eliminated haunches and low ered the deck. ; And then they picked the paint system that would last the longest and look the best on high-strength steels. It was an Oncor M50 system, of course. Three-coat "Defense in Depth." The Basic Lead Silico Chromate pigment system that puts corrosion resistance into every coat. Plus weatherability. Plus tintability--to just about any color wanted. After all, it's the paint system designed for the best designs. If you'd like more information on Oncor M50 just write National Lead Com pany, Room 3101, 111 Broadway, New York, New York 10006.
