Structural Steel Inspection  Structural steel engineering inspection encompasses all the required testing and inspection content for materials and projects, including raw materials, welding materials, welded components, fasteners, welds, bolted ball joints, coatings, etc. of steel structures and special equipment. Comprehensive inspection techniques for main structure projects, such as sampling inspection, chemical composition analysis of steel, coating inspection, building materials, waterproofing materials, and energy-saving inspections.

Structural Steel Inspection Content:

Non-destructive testing

NDT (Non-destructive Testing) is an indispensable effective tool for industrial development, reflecting a country's industrial level to some extent, and its importance has been universally recognized. NDT (Non-destructive Testing) refers to the use of characteristics like sound, light, magnetism, and electricity to detect the presence of defects or non-uniformities in an object without damaging or affecting its performance. It provides information on the size, location, nature, and quantity of defects, enabling the determination of the technical status of the object being tested (such as whether it's qualified or its remaining lifespan).

Based on the material, structure, manufacturing process, working medium, operating conditions, and failure modes of the inspected items, anticipate the types, shapes, locations, and directions of potential defects, and select an appropriate non-destructive testing method.

2. Performance Testing

1) Steel mechanical testing

Test the mechanical properties of steel used in steel structures, such as tensile, bending, impact, and hardness.

2) Fastener Mechanical Testing

Test the mechanical properties of fasteners used in steel structures, such as the coefficient of friction and axial force.

3) Metallographic Analysis

Perform metallographic analysis on the steel used in steel structures, such as microstructure analysis and microhardness testing.

4) Chemical Composition

Conduct a chemical composition analysis on the steel used for steel structures.

5) Paint Testing

Inspect coatings used for surface painting of steel structures.

6) Stress Test

Test and monitor stress variations in critical areas during the installation and unloading of steel structures.

7) Complete Technical Set

The integration of comprehensive testing technologies, including mechanical property tests of steel structures (tensile, bending, impact, hardness), mechanical property tests of steel structure fasteners (coefficient of friction, axial force), metallographic analysis of steel structures (microstructure analysis, microhardness test), chemical composition analysis of steel structures, non-destructive testing of steel structures, stress testing and monitoring of steel structures, coating testing, salt spray testing, etc., is referred to as steel structure testing technology.
