COR-TEN steel is a trademark registered product of United States Steel Corporation. It was developed in the 1930’s, mostly to use in railroad coal cars. It is a special blend of steel alloys that, when exposed to weather, develop a thin, protective rust layer that coats and protects the metal. Some of its early use in civil engineering projects in the 1960’s gave way to architectural uses not long after.
It was an ideal choice for the New River Gorge Bridge because it solved a couple of problems. The expense of painting such a large structure would have been cost-prohibitive. Using COR-TEN not only saved $300,000 in construction costs, but also an estimated $1,000,000 every time the Bridge would have had to been painted.
Hersheypark has theirs closed, is it Chance or KMG?
