A hoarding is a large, outdoor advertising board, usually placed in high-traffic areas like roadsides or city centers, used to display promotional messages or branding for a company, product, or evevt; essentially a big billboard-style banner for outdoor advertising.
Large size: hoardings are significantly larger than regular banners, designed to be easily visible from a distance.
outdoor placements: they are typically mounted on structures in public spaces to reach a wide audience.
construction sites: hoardings are also often used around construction sites to provide safety barriers while also displaying information about the project.
