Steel Structure Building Inspection
Steel structure is a structure composed of steel materials and is one of the main types of building structures. The structure is mainly composed of beam steel, steel columns, steel trusses and other components made of section steel and steel plates, and adopts rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, galvanizing, etc.

Product Introduction
Steel structure engineering inspection
Steel structure is a structure composed of steel materials and is one of the main types of building structures. The structure is mainly composed of beam steel, steel columns, steel trusses and other components made of section steel and steel plates, and adopts rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, galvanizing, etc. Welding seams, bolts, or rivets are usually used to connect various components or parts. Due to its light weight and easy construction, it is widely used in large factories, venues, super high-rise buildings and other fields. Steel structures are prone to rusting, and generally require rust removal, galvanizing, or coating, as well as regular maintenance.
Applicable fields
Steel structures: TV towers, microwave towers, communication towers, high-voltage transmission line towers, petrochemical towers, atmospheric monitoring towers, rocket launch towers, travel watchtowers, drilling towers, exhaust towers, water towers, chimneys, etc;
Plate shell steel structure: large oil storage tanks, gas storage tanks, furnace shells, blast furnace structures, large hydraulic structures, ship lock gates, etc;
Industrial plant steel structure: open hearth workshop, primary rolling workshop, mixed iron furnace workshop, cast steel workshop, hydraulic locomotive workshop, forging workshop, shipyard workshop, assembly workshop, workshop roof, crane beam, etc;
Lightweight steel structures: industrial plants, construction of small and medium-sized houses, sports stadium stands, canopies, small warehouses, etc;
Other steel structures: steel structures for adding floors, steel structures for villa expansion, steel structures for tower structures, steel structures for stairs, steel structures for garage entrances and exits, steel structures for mall entrances and exits, and steel structures for floors (flat to sloping).
Test items
Magnetic Particle Testing (MT): Used for the inspection of workpieces with a thickness greater than 8mm, it can detect defects such as internal cracks and delamination in steel structures
Penetrant testing (PT): for defects that may occur inside steel structure welds, such as porosity, pinholes, inclusions, porosity, cracks, segregation, lack of penetration, and insufficient fusion
Ultrasonic testing (UT): can detect surface and near surface defects (such as cracks, inclusions, streaks, folds, pores, etc.)
Radiographic testing (RT): capable of detecting surface open defects in various non porous materials
Other testing items
Steel mechanics testing: Testing the mechanical properties of steel used in steel structures, such as tension, bending, impact, hardness, etc.
Mechanical testing of fasteners: Testing the mechanical properties of fasteners used in steel structures, such as anti slip coefficient, axial force, etc.
Chemical composition: Conduct chemical composition analysis on the steel used in steel structures.
Stress testing: Testing and monitoring the stress changes in key areas during the installation and unloading process of steel structures.
Complete set of technology: The integration of the above items, including steel structure mechanical performance testing (tension, bending, impact, hardness), steel structure fastener mechanical performance testing (anti slip coefficient, axial force), steel structure metallographic testing analysis (microstructure analysis, microhardness testing), steel structure chemical composition analysis, steel structure non-destructive testing, steel structure stress testing and monitoring, coating testing, salt spray testing and other complete testing technologies, is called steel structure testing technology.
