A signboard is a type of advertising or information display that is typically mounted on a building or in a public area to convey a message to a large number of people. Signboards come in various shapes, sizes, and materials, and can be designed to convey a variety of messages such as advertising a business, providing directional information, displaying safety messages, or promoting a product or service.
 

Signboards can be made from a variety of materials including metal, plastic, wood, and glass. They may be illuminated or non-illuminated and can be mounted on poles, walls, roofs, or other structures. The design of a signboard should be eye-catching, informative, and easy to read from a distance.

Signboards are commonly used by businesses to promote their products or services and to attract customers to their location. They are also used in public areas such as airports, bus stations, and hospitals to provide directional information and display safety messages. In some cases, signboards may be subject to local regulations or zoning laws, and it is important to consult with local authorities before installing a signboard.
