Laser Cleaning Machine for Bridge Maintenance

Feb 25,2026

Traditional bridge steel structure rust removal and maintenance has long relied on sandblasting (shot blasting) and chemical cleaning. However, these traditional processes have many insurmountable drawbacks: sandblasting generates large amounts of dust and fumes, polluting the surrounding environment (rivers, air) and posing a threat to the health of operators; chemical cleaning generates wastewater with high treatment costs and complex processes; and mechanical grinding easily damages the steel substrate, often achieving only Sa2 level cleanliness, which is insufficient to meet the stringent adhesion requirements of high-performance anti-corrosion coatings, especially when dealing with complex structures such as rivet joints and U-rib welds.

Recently, Shandong Qiangyuan Laser Of SDIIT Ltd. (SDQY Laser), leveraging its deep expertise in intelligent equipment manufacturing, has achieved a major breakthrough in the maintenance of large-scale bridges with its independently developed high-power laser cleaning machine. It has been successfully applied to rust removal, paint removal, and pre-welding pretreatment of key components including main bridge cables, U-rib welds, and guardrails. This innovative technology, with its superior characteristics of precision, non-destructive operation, environmental friendliness, and high efficiency, is reshaping traditional bridge maintenance operations and providing core equipment support for the intelligent and green transformation of the infrastructure maintenance industry.

 

Features of laser cleaning: Zero contact, zero damage, achieving Sa3-level top-tier cleanliness; Solving the cleaning challenges of complex structures; Low noise, zero emissions; Reduced overall operating costs.

SDQY Laser's laser cleaning technology is not only a powerful tool for addressing current environmental and quality challenges, but also a core driving force propelling the entire bridge maintenance industry towards intelligent and refined transformation. Choosing SDQY Laser means choosing a cleaner, smarter, and more forward-looking non-destructive surface cleaning method.
