❝ 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.

We’ve had issues with staff and visitors wandering into areas they shouldn’t, so we wanted signage that was unambiguous. This sign makes the requirement really clear without needing extra explanation. The curved top design looks professional and matches the rest of our site signage. Print quality is crisp and the colours stand out well. It arrived well packaged and went up easily. Overall, it’s helped us tighten up access control in a simple, visible way.

Bought this for a restricted plant area and it’s been really effective. The curved top gives it a more polished look than our old printed notices. It’s clear from a distance and reinforces our safety rules. Arrived quickly and in good condition.
