They are mounted to doors with nails or screws, an adhesive backing, a slider, Velcro or magnets. Door nameplates usually contain one to two lines of text, and sometimes a graphic like a company logo. They are common in public buildings like schools, colleges, hospitals, med centers and religious buildings to help direct visitors.
Workplaces like offices, factories and warehouses use nameplates on doors to improve the company’s professionalism and organization. All nameplates are custom to some degree because the text for each differs for each plate. Sizes also vary, but the most common dimensions are two by eight inches. Buildings with multiple door nameplates order them with a uniform color, design and font to maintain consistency and organization.
Door nameplates work with a very limited amount of space, so the text must be concise and pertinent. Unlike public building and workplace door nameplates, which are designed with aesthetics and decoration in mind, industrial nameplates are manufactured to resist extreme temperatures, moisture and chemical corrosion.
There are a wide variety of options when it comes to door nameplate design. They are manufactured from many different materials, the most common of which are aluminum, brass or copper. They may be painted, embossed with gold, silver or black dyes to improve the font readability, polished or lacquered with clear coating to improve both resistance and appearance.
Standard nameplates are rectangular, but they are available in a number of different shapes, including oval and custom made cutouts with borders. The text may be printed with paint or ink using screen printing. Embossed nameplates are squeezed through two counter dies that use heat and pressure to create three dimensional text, which is then filled in with a dye.
Engraved nameplates are the most common method of producing three dimensional text using chemicals, diamond, needles or lasers to wear away the surface in the custom text design. Etched and embossed fonts last much longer than printing and are easier to read. Plastic nameplates are hot stamped with a ram that has a mold of the desired text, while wood nameplates are whittled, carved or labeled by other methods. Most nameplate manufacturing is done by CNC operated machinery.
