Professional design, supply, and installation of all types of traffic signs across the UK.
Learn More 🚀The No Admittance Authorised Personnel Only Sign is a vital safety tool for clearly marking restricted access zones within workplaces, construction sites, and utility environments. With a bold red prohibition symbol and clear text, it helps prevent unauthorised entry, reduce liability, and maintain full compliance with ISO 9001 safety standards.
Manufactured in the UK and available in a durable 500×300 mm format, this sign is ideal for placement on doors, walls, fences, or machinery housing. Constructed from premium substrates such as anti-slip vinyl, Foamex, Corriboard, and composite aluminium, it’s built for both indoor and outdoor use. Standard and heavy-duty floor sign variants are also available.
This sign supports workplace safety by clearly informing staff, contractors, and visitors that the marked area is restricted to authorised personnel only — keeping people safe and operations secure.
This high-contrast, red-on-white warning sign uses a universal prohibition symbol to convey a clear no-access message. Whether wall-mounted or applied as a floor sign, it maintains visibility even under demanding environmental conditions.
Its anti-slip overlaminate adds extra grip for foot traffic when used as a floor sign — perfect for industrial settings, labs, warehouses, and workshops.
