Metal Roof System Inspection
   Metal roof inspection is the use of certain technical means and methods, the quality of its structure to check the determination, the implementation of dynamic monitoring, is qualified by the testing unit of the quality of the metal roof testing, assessment, and issue a report on the process.   The main role of metal roofing system is to exclude rainwater, prevent leakage, and at the same time, it also has to withstand wind and rain, snow, dust, construction workers, other roof facilities and other loads, taking into account other architectural functions such as aesthetics.　Metal roofing system wind resistance test is to verify the safety of the whole roofing system (e.g. connection between fasteners, connection between purlins and brack...

Structual Steel Health Monitoring
Housing quality inspection is the use of certain technical means and methods, through the existing housing quality (rather than the quality of the project under construction), especially its structural quality inspection and determination, the implementation of dynamic monitoring, in order to play a role in safeguarding the safety of people's lives and property in the country, to promote the full and rational use of existing housing resources, to ensure the stability of the community, and therefore has a huge social and economic benefits. According to the relevant building codes (civil, commercial and industrial buildings) and other different building codes, a sampling inspection of components is carried out for older houses. Modeling and c...

Comprehensive Inspection of Buildings
The principle of the metal roof panel wind resistance performance testing system is to apply uniform wind load to the test specimen under simulated wind load conditions in the laboratory, evaluate the deformation and connection fixation of the test specimen as a whole, and simulate the actual wind conditions of the system through multiple cyclic loading, effectively verifying the wind resistance performance of the test object.

Mechanical Performance Test
Mechanical performance testing refers to the process of comprehensively checking and evaluating the performance of mechanical equipment through a series of tests and assessments. It is mainly used to determine whether the mechanical equipment meets the design requirements and whether it can achieve the expected stability and durability in actual work. Mechanical performance testing is essential to ensure the safety, improve the quality and maintain the stability of mechanical equipment. A comprehensive assessment of the performance, structure and function of mechanical equipment can identify potential problems and failures, and take timely action. Through the application of laboratory tests, field inspections and non-destructive testing met...

Chemical Element Analysis
The significance of chemical analysis of metal elements is mainly in the following aspects: ① Determine the composition of the metal: chemical analysis of metal elements can be used to determine the elements contained in different metal materials and the content of the elements, such as pure copper, brass, stainless steel and so on. This helps to detect whether the composition of the alloy meets the standards and manufacturing requirements. ② Distinguish between different metal materials: chemical analysis of metal elements can be applied to material identification by analyzing the composition of the material to determine the different metal types to which it belongs. For example: three-element analysis of stainless steel and aluminum hydro...

Non-Destructive Testing
Non-destructive testing refers to the inspection of the internal mechanical materials does not damage or does not affect the use of the performance of the object to be tested, does not harm the internal organization of the object to be tested under the premise of the use of the internal structure of the material anomalies or defects in the existence of the changes caused by the thermal, acoustic, optical, electrical, magnetic and other reactions to the physical or chemical methods as a means to use the modern technology and equipment and equipment, the structure of the specimen on the interior and the surface of the state and the defects in the type, quantity, shape, nature, location, size, distribution and their changes. NDT is a method to...

Welding Procedure Qualification
Welding Procedure Qualification ( referred to as WPQ) in order to verify the correctness of the proposed welding process for the welding of weldments and the evaluation of the results of the test process. Welding procedure qualification is an important measure to ensure quality, for the formal development of welding procedure guide or welding procedure card to provide a reliable basis. Welding process is an important measure to ensure the quality of welding, it can confirm the correctness and reasonableness of the welding process for a variety of welding joints prepared by the welding process instructions. Through the welding process assessment, test according to the proposed welding process instructions welded welded joints whether the use...
