Factors Prone to Quality Problems in Steel Structure Engineering

The steel structure has a lightweight and is easy to construct. It is widely used in large span factories, stadiums, super high-rise buildings, and other fields. Quality problems are prone to occur in steel structure projects, so what are the factors that are prone to quality problems in steel structure projects? Let's take a look together next.

Here is the content list:

• The complexity of steel structure

• The severity of steel structure

• Variability of steel structure

• Frequency of steel structure

The complexity of steel structure

The complexity of construction quality problems of steel construction projects is mainly manifested in the many factors that cause quality problems, and the reasons for quality problems are also complicated. Even if the quality problems are of the same nature, the reasons are sometimes different, so that the quality problems can be analyzed and judged. And processing adds complexity. For example, steel construction welding cracks can occur either in the weld metal or in the heat influence of the base metal, either on the surface of the weld or inside the weld; the crack direction can be parallel to the weld bead or it can be perpendicular to the weld bead, and the cracks may be cold cracks or hot cracks; the reasons are also an improper selection of steel construction welding materials and improper preheating or post-heating.

The severity of steel structure

The seriousness of the construction quality problems of steel construction projects is: in general, it affects the smooth progress of construction, causes delays in the construction period, increases costs, and in serious cases, buildings collapse, cause personal injury and death, property damage, and cause adverse social impacts.

Variability of steel structure

Steel structure construction quality problems will continue to evolve and change along with changes in the outside world and the extension of time, and quality defects will gradually manifest. For example, due to the change of stress in the weld seam of steel structure, the original weld seam without cracks has cracks: delayed cracks can be produced due to the activity of hydrogen in the weld seam after welding. Another example is the long-term overload of the steel structure, the steel components will be bent and deformed under the arch, which will cause hidden dangers.

Frequency of steel structure

Since modern buildings in our country are mainly concrete structures, the managers and technicians engaged in steel structure construction are relatively unfamiliar with the production and construction technology of steel structures, and concrete construction personnel who are mainly migrant workers do not understand prefabricated steel structure projects. The scientific construction methods of the company lead to frequent accidents during the construction process.

Qingdao Xinguangzheng Steel Structure Co., Ltd, was founded in 1997 and listed in New OTC Market in 2015. The above is related to the factors that are prone to quality problems in steel structure engineering. We supply one-stop solution from design, manufactory, installation with our professional team.
