Acid etching is a process of using acids to cut into the unprotected parts of a masked metal surface.
Typical metals etched in the manufacture of signs include stainless steel, brass, aluminium and copper.
Glass sheet can also be acid etched.
Very fine detail can be reproduced using this process, making acid etching ideal for small type, photographics and fine line drawings. As the image is physically embeded into the surface, acid etching is highly durable and long lasting, for both internal and external applications.
Acid etching is ideal for general signage, corporate identity and architectural signs, heritage and interpretive signs, as well as schematic diagrams.
Finished acid etched signs can then be fabricated or incorporated into new or existing installations.
