Unprinted Galvanized Steel Sign Blanks
Blank sign plates are galvanized steel sheets with no symbol or text yet, used as the base for road signs and panels. They give you flexibility when you want to apply your own reflective sheeting or print, refresh worn signs or make a custom warning panel. Sign shops, municipal sign teams, road contractors and factories use blank plates to produce their own signs. Every plate in this category comes with size and thickness options.
Shapes and the Signs They Are Used For
- Triangle: the shape used for danger warning signs.
- Round: used for prohibition, restriction and mandatory signs.
- Octagon: the shape reserved for the STOP sign.
- Square: suits information, parking and direction signs.
Choosing Size and Thickness
Choose the size by viewing distance and road type; faster roads call for larger signs. For signs used on public roads, following the dimensions in the national highway signage standards is recommended. Thicker plates are more rigid, so for large signs and windy locations a heavier gauge helps prevent bending. The galvanized coating protects the steel against rust outdoors. Cleaning the surface of grease and dust before applying film or print helps it bond better.
Mounting
