    Trade Customer Success Story
    “Working with Rainbow Safety has transformed our safety sign sales.”

    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 £5,100 in a single order.

    Previously we were regularly asked to supply safety signs but couldn’t compete with internet prices while maintaining healthy margins. Working with rainbowsafety.co.uk.

    Applied the vinyl onto hoarding near the entry point, and it’s viral‑grade at catching attention—hasn’t lifted or faded. Professional look and lovely and clear to anyone approaching the site.

    Fixed the rigid plastic sign to a gate with cable ties—tough and hasn’t budged. Messaging is bold and clear from across the yard, so it’s doing its warning job properly.

    Used the Correx board—perfect for shifting around as work moved. Still held firm and visible even after a couple of wet days. Simple, effective, and does what it’s supposed to.

    Went for the vinyl sticker applied on a barrier, and it’s stayed put through wind and drizzle. Clear warning and easy to see, which is exactly the aim when work’s in progress.

    Chose the rigid plastic version and it’s been spot on for a long‑term site works zone. The text remains bold even in dull weather, and it’s robust enough to take a few knocks without looking worse for wear.
