❝ 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.

The sign’s durability is impressive and it’s been up for months with no fading or damage, even in rough weather. Easy to attach to our fencing, and delivery was fast.

We needed clear signage for a city centre project, and this sign does the trick. The message is impossible to miss and has helped us keep the site secure from day one.
