Laser Marker


Nireco's laser marking system can mark directly onto the sides or ends of thick plates moving on the production line. It can write text information necessary for quality control and inventory management, and barcodes that are essential for logistics management, yielding major cost reductions.
Using our abundant experience and expertise in the steel industry, this marking system marks quickly and accurately, on hot metal or on cold metal. It is also highly environmentally stable, for dependable long-term use.
