Abstract

A stamped steel detectable warning tile and method of forming such includes preforming structures in the tile and subsequently coining the structures to form tactile portions to provide satisfactory end results. Further, the tactile portions can be formed in a staggered fashion along a press to distribute tonnage and extend the lifespan of the press, as well as control a curvature of the tile due to the press operations.
