High-Temperature Signs

You don’t always see heat — but you can feel it. And in industrial or technical settings, that’s not good enough.
High-temperature signs exist to give early, unmissable warning: “This surface isn’t just warm. It can burn.”

These signs are found near boilers, heating elements, exhaust ducts, engine housings, soldering stations — anywhere residual or active heat poses a risk.
In many cases, the equipment looks harmless when powered down. Which makes clear signage even more important.

We’ve supplied these warnings in rigid aluminum, laminated vinyl, and heat-rated polycarbonate — depending on proximity and mounting surface.
In some environments, the sign is mounted directly onto metal. In others, it’s positioned upstream — giving a few seconds’ notice before the person gets too close.

These signs often live alongside electrical safety signs and chemical hazard labels, especially in mechanical rooms or mixed-use lab spaces. Consistency in visual language — yellow triangles, black icons, bold wording — makes the system more effective overall.
