Steel Structure Inspection
Steel structure engineering is a construction approach that primarily utilizes steel materials, with structural components such as steel beams, steel columns, and steel trusses fabricated from structural steel sections and steel plates. These components are typically connected to one another by welds, bolts, or rivets, making steel structures one of the principal types of building structures.

Product Description
Steel structure engineering is a construction system primarily composed of steel materials, with structural members such as steel beams, steel columns, and steel trusses fabricated from structural steel sections and steel plates. These components are typically connected to one another by welds, bolts, or rivets, making steel structures one of the principal types of building structures. Owing to their relatively light self-weight and ease of fabrication, steel structures are extensively employed in large industrial plants, sports venues, and ultra-high-rise buildings. Quality inspection for steel structures generally encompasses: physicochemical testing of raw materials (including elemental analysis and mechanical property assessment); nondestructive testing of welded joints (using radiography, ultrasonic testing, magnetic particle inspection, and liquid penetrant testing); inspection of anti-corrosion and fire-resistant coatings (covering coating thickness and adhesion); deformation measurement (including deflection, verticality, and planar curvature); and verification of the torque coefficient for high-strength bolts and the slip-resistance coefficient of friction surfaces.
This includes mechanical property testing of raw materials and welded joints (tensile, bending, impact, and hardness tests), mechanical property testing of fasteners (wedge load, torque coefficient, axial force, etc.), chemical composition analysis of raw materials, non-destructive testing of welded joints, friction surface slip-resistance coefficient testing, coating inspection, and deformation monitoring of steel space frame structures, among others.
