Construction Site Keep Out Sign – 400 x 300mm

This Construction site keep out sign is a clear message that only authorised personnel should be on the premises.

The bold yellow background grabs attention straight away, while the black triangle with an exclamation mark reinforces the warning. It’s the kind of sign you’ll see posted at temporary fencing, hoardings, or site entrances—anywhere the public might otherwise try to pass through.

The sign’s built from strong, weatherproof material, so it’ll hold up in tough site conditions. Whether it’s wind, rain, or dust, the message stays visible. You can install it with screws using the pre-drilled holes, or stick it in place with an adhesive back—it depends on your setup and how fast you need it up.
