On automobile wheels such as: section steel wheels, tubeless steel wheels, forged aluminum wheels and various steel structures such as: building steel structures, equipment steel structures, and steel structure bridges, QR codes will be marked with laser engraving and laser etching. We commonly call it steel coding. Due to the hard and reflective medium of this kind of 2D code, the code will be deformed, highly reflective, and inconsistent in clarity. This kind of dot-matrix code has high requirements on the barcode scanner.

The XT6201GHD high-precision and high-density barcode scanner developed and produced by Xingtong IoT can scan all kinds of steel structures. 

The XT6201GHD series adopts a new generation of industrial decoding algorithm and has comprehensive fast reading ability, which can realize the reading of paper codes and direct parts identification barcodes with a density of more than 3mil in the fastest time of 50ms. Excellent infrared sensing ability, can detect object distance changes up to 1000px, and quickly start induction reading within 100ms. The structure design including the high elastic trigger makes the product have excellent reliability and stability, and can withstand a free fall from 1.8m concrete.
