Grunge Rust AI Display Font Generator

Grunge Rust is a corroded metal display: an iron-oxide surface with pitting, flaking and industrial decay eating into the letterforms. It carries the weight of weathered steel and abandoned machinery — the register of heavy metal, post-apocalyptic and industrial branding.

There is no installable file. You type your text and the generator corrodes those specific letters, placing the rust, pitting and flaking on your actual shapes, and returns a high-resolution image.

Heavy metal and hardcore artwork, post-apocalyptic game and film titles, industrial and workshop branding, motorcycle and garage graphics, survival and tactical gear, distressed poster work. Set it large so the corrosion texture reads.

Because iron oxide takes up more room than the iron it replaces, so rust is self-destructive in a way most corrosion is not. Some metals form a protective patina: copper's verdigris and aluminium's oxide are dense, well-fitted layers that seal the surface and stop further attack. Rust does the opposite — the oxide it forms is bulkier than the original iron, so as it grows it swells, cracks and lifts away in flakes, constantly exposing fresh clean metal underneath to the air and moisture. That new metal then rusts too, flakes off in turn, and the process eats steadily downward, gouging pits and craters rather than sitting still as a coat. That is why rust reads as active decay, something being consumed, and why the pitted, flaking texture looks so different from the smooth even darkening of a metal that protects itself.
