Steel, aluminum alloys, and other large metal materials are indispensable components in infrastructure construction projects. How to mark and classify these materials efficiently—while ensuring that the identification remains intact during transportation, loading, unloading, and assembly, and stays legible even after exposure to harsh natural environments—is a critical challenge for the industry.

Compact portable handheld laser marking machines offer a lightweight, professional, and highly flexible solution. Equipped with a 1064 nm fiber laser, they are specifically designed for high-hardness and high-density metal materials, delivering permanent, high-contrast markings.

With a total weight of less than 10 kg and a built-in battery, the system enables easy outdoor marking without external power supply. Its simplified editing interface and support for diverse marking content allow laser marking to truly become a one-stop identification solution for infrastructure projects.
Thanks to their light weight and ease of transportation, installation, and dismantling, plastic pipes have gradually become mainstream materials in pipeline construction. Meanwhile, power cables—an essential part of modern energy systems—play a mission-critical role in daily life.
For manufacturers, whether materials are buried underground or exposed outdoors, the fragility of traditional labels significantly reduces service life and increases maintenance costs.
Laser marking machines, however, feature fine laser spots and minimal smoke generation. Their “cold processing” technology, when applied to PVC pipes, wires, and cables, effectively protects the material surface from damage, preserves material performance, and produces no unpleasant odors during production.
On automated production lines, laser marking systems can also be integrated with proprietary software and vision inspection systems to detect markings in real time. Content such as serial numbers, alphanumeric codes, QR codes, and barcodes can be verified, with defective products automatically identified and rejected.
In real-world construction applications, a wide variety of materials are involved. With multiple series of laser marking equipment and self-developed technologies, DAT Laser provides professional, customized laser marking solutions—eliminating the long-term risks and limitations of traditional labeling.
This is the last one.
