Fences are a great way to surround a construction or building site and keep it secure, especially when all the workers have gone home. However, fences won’t always deter a determined thief and that’s where our temporary ‘This fence is alarmed’ construction signs come in handy.

Available in a variety of different materials and sizes, their clear design and messaging will ensure any intruders are fully aware that your fences are alarmed and will think twice before trespassing.

When keeping your construction or building site secure, our industrial heavy-duty cable ties are perfect for attaching construction site warning signs to fences, walls and stanchions.

To keep fence gates locked, we recommend using our outdoor long shackle padlocks which are both durable and weatherproof for long-lasting outdoor security.
