In 1981, Serra installed «Tilted Arc», a gently curved, 3,5 meter high arc of
rusting mild steel in the Federal Plaza in New York City.
The
mild steel version was in the workshop and, rather than let it
rust, Gary at Twin Engineering suggested that, since it was quite easy to handle, it would be perfect for a powder - coat finish (baked on enamel) and it would give us a chance to see what a local firm could do.
