Security Signs

Construction Security Signs help protect building sites, contractors and equipment by communicating security measures, access restrictions and surveillance information. Also known as site security signs, construction site security notices or restricted access signs, they help deter unauthorised entry and reinforce site security procedures.

Widely used by construction companies, developers, principal contractors, facilities managers and property owners, these signs provide clear warnings and instructions to workers, visitors and members of the public.

Common installation locations include site entrances, perimeter fencing, hoardings, access gates, storage compounds, plant areas, welfare facilities and restricted work zones.

Manufactured in the UK and available in durable materials suitable for outdoor environments, Rainbow Safety construction security signs help improve site security while maintaining a professional appearance throughout a project.
