Ding Testing & Inspection: Non-Destructive Testing (NDT) of Steel Structures, The Robust Foundation Safeguarding Building Safety
Non-Destructive Testing (NDT) of steel structures is a technology used to assess the integrity and safety of steel structures through non-destructive methods to detect potential defects and damage, preventing structural failures and extending service life. Ding Testing & Inspection provides professional NDT services for steel structures to ensure their integrity and safety, meeting the high standards of the construction and engineering industries.
Service Introduction
Steel structures, composed of steel materials, are one of the main types of building structures. They are typically made from steel beams, columns, trusses, and other components, and are protected against rust and corrosion through processes such as silanization, manganese phosphating, washing and drying, and galvanizing. These structures are connected using welds, bolts, or rivets and are widely used in large factories, stadiums, and super-high-rise buildings due to their light weight and ease of construction. However, steel structures are susceptible to rust and require regular maintenance.
