Metal Structure Testing

Water conservancy and hydropower engineering hold a pivotal position in national infrastructure construction, undertaking vital functions such as flood control, irrigation, power generation, and water supply. As the core material for key equipment such as gates, hoists, penstocks, and trash racks, the quality and safety of metal structures directly affect the operational safety and service life of the entire project. We have a professional testing team certified by the Ministry of Water Resources. We can provide differentiated testing and verification services for metal structures with varying working conditions, materials, and service lives, covering material composition, mechanical properties, welding quality, anti-corrosion coatings, fatigue damage, and remaining life assessment. This helps your metal structure demonstrate its unique safety label in "milestone projects."
