Steel Structure Testing

Steel structure engineering refers to structures primarily made of steel and is one of the main types of building structures. Steel structure engineering testing includes all required tests and inspections for materials such as steel structure welds, raw materials, welding consumables, welded components, fasteners, bolts, bolted ball joints, coatings, and the entire project. Driven by relevant national policies, steel structure engineering has developed rapidly over the past decade, leading to a surge in demand for non-destructive testing (NDT) and material testing.

We have a professional testing team capable of providing specialized, meticulous services, ensuring your products maintain quality and safety while highlighting their unique characteristics in the market.
