❝ Trade Customer Success Story
“Working with Rainbow Safety has transformed our safety sign sales.”
Before partnering with Rainbow Safety, our safety sign sales were less than £300 per month.
With the support and marketing tools provided, our sales have grown to over £3,000 per month.

Fire extinguisher servicing margins are not what they used to be, so supplying safety signs has become a valuable additional revenue stream for our business. On one warehouse safety survey alone we invoiced £5,100 on a single order.

We can now compete with internet prices and still make a healthy margin.

We were regularly asked to supply safety signs, but struggled to compete with internet prices while maintaining a worthwhile margin.

Working with Rainbow Safety has changed that. We can now offer our customers a competitive range of safety signs while still making a healthy margin for our business.

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.

Aidan Murphy

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.

Zoe Palmer

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.
