An old, heavily rusted corrugated metal panel, deeply discolored with shades of deep orange, reddish-brown, and dark gray where the rust has eaten away. Its surface is rough and uneven, covered in flaky patches of oxidation, and exhibits significant pitting and corrosion. The panel is noticeably bent and warped, with its characteristic wavy ridges irregularly creased and contorted, giving it a brittle, jagged feel at the edges.
