Went with the Correx version for a short-term setup. Light, easy to fix, and the print stands out well. Might go for the more rigid option next time, but this worked just fine for what was needed.

Mounted the rigid plastic sign with cable ties near a walkway. Feels durable and hasn't budged. Definitely helps flag up the work zone to both workers and delivery drivers.

Correx board version worked well on temporary fencing. Lightweight and quick to reposition when needed. Visibility is great, even with all the site dust flying about.

Used the rigid plastic version at the site entrance. It's held up brilliantly through wind and rain, and the print stays sharp. Makes it clear there's active work going on.
