Durable, high-contrast marking solutions for tough industrial environments.
Why REA for Metal Tube Marking?
Steel manufacturing is an unforgiving environment. Production lines move large, heavy and sometimes hot objects and the systems are not designed to be stopped and started. This means if the marking technology is not fit for purpose, it will fail, adding huge cost in unmarked product.

In the steel and metal sector, a wide variety of semi-finished products and components need to be clearly and permanently marked. The conditions are often extreme – for example, when coding freshly produced, red-hot steel directly on the line.
Beyond high temperatures, marking and coding systems must also perform reliably in environments with:
- Dust, dirt and vibrations
- Oily or uneven surfaces
- Varying material compositions
- Extended pauses between production runs
To achieve full process automation, coding is typically carried out inline during production. This means systems need to be seamlessly integrated into existing facilities, delivering consistent results at high speed while withstanding tough industrial conditions.
