A practical UK guide to specifying valve tags. Materials, numbering systems, standards, fixings and how to prepare a tag schedule for your engraver.

Every traffolyte label is a two colour decision. The surface cap layer provides the background, the core layer provides the lettering, and the combination you choose does more work than most specifiers realise. In industrial and electrical environments, colour is not a styling choice. It is a signalling system that maintenance personnel read before they read a single word.

The short answer is 20 to 30 years in typical indoor industrial environments, and frequently much longer. It is entirely normal to open a distribution board commissioned in the 1980s and find the original traffolyte labelling still perfectly legible. In many installations the labels outlast the equipment they identify, and sometimes the company that made the equipment.

Traffolyte and impact acrylic look similar but perform very differently. Compare heat resistance, durability, appearance and cost to specify the right material.

Why engraved traffolyte labels are widely used across food manufacturing, supporting hygiene standards, equipment identification, maintenance efficiency and long-term reliability.

When people picture a solar farm, they normally think about rows of panels stretching across a field. What they don’t usually think about is the amount of electrical infrastructure sitting behind those panels, and how much of it relies on clear identification once the site is operational.

Traffolyte labels turn up on almost every electrical panel, valve system, and piece of industrial equipment in the UK. Most people who work with them know what they look like and what they do. Fewer know what the material actually is, where it came from, or why it has stayed the go-to choice in industrial labelling for the better part of a century.

Learn when to specify traffolyte labels inside electrical control panels, recommended thickness, character sizes, sequencing tips, and how to avoid common panel labelling mistakes during installation.

Traffolyte valve tags have been around for a long time for a reason. Not because they’re clever but because they tend to keep doing the job when other options slowly stop.

Walk up to any electrical control panel in a UK industrial facility and you'll almost certainly find traffolyte labels on it. Circuit identification, isolator markings, warning notices, engraved laminate has been the standard for decades.

Traffolyte labels have been a standard across UK electrical and industrial infrastructure since the late 1920s because their performance characteristics genuinely suit the demands of long-term industrial identification.

HV and LV switchgear signage and labelling should be planned early, delivered accurately, and updated quickly when changes occur. This significantly reduces commissioning delays, supports first-pass inspection, and improves overall project handover.
