No Unauthorised Entry Building And Construction Site Signs
No Unauthorised Entry Building & Construction Site Signs combine site safety, PPE and access-control messages in one clear display. They help you warn visitors, parents, staff and contractors at building entrances, gates and work areas where construction hazards must be understood before entry.
Where No Unauthorised Entry Building & Construction Site Signs Should Be Installed
You should install this sign at site entrances, pedestrian gates, hoarding lines, compound access points and temporary work areas where people may approach before signing in. Clear front-facing placement helps you stop casual entry, reinforce PPE rules and direct visitors towards authorised control points.
Choosing a Practical Viewing Distance for Your Site Entrance
Select the size around how early you need people to act. Smaller signs suit controlled doorways, while larger formats are better for vehicle gates, wide hoarding lines and busy construction approaches where the message must be seen before a person reaches the hazard.

| H 400 x W 300 mm | Approx. 3–6 metres | Doors, cabins and narrow access points |
| H 600 x W 450 mm | Approx. 6–10 metres | Pedestrian gates and hoarding entrances |
| H 800 x W 600 mm | Approx. 10–16 metres | Main site approaches and mixed access routes |
