Nowadays, steel structure buildings are widely used at home and abroad. Many public buildings, logistics centers, and sports venues in China use steel structure buildings. The appearance of these buildings promotes the development of steel structure fabrication. However, there will inevitably be some difficult problems during the construction process. Experienced steel structure manufacturers will record and solve the problems to avoid similar problems next time.

Qingdao Havit Steel Structure Co., Ltd. has been committed to designing, fabricating, and exporting steel structure buildings for more than ten years. Our steel building projects have been exported to more than a dozen countries worldwide, and the quality, price, and after-sales service have been widely recognized and praised by customers. Whether customers need third-party testing, we have our own professional quality inspection team and system to ensure that the project quality meets customer requirements and standards.

Steel structure buildings have their professionalism and complexity, and some difficult problems will inevitably arise during the construction process. However, our production team will record and seek the best solution in time and continue to optimize so that some problems no longer appear.

How to avoid problems in steel structure fabrication

Raw materials

Raw materials are unloaded at will during transportation and storage, and they are piled up in a disorderly manner, resulting in deformation of components, bruises, and environmental pollution; when the raw materials of steel structure buildings are processed, the cut plate specifications are different, it will lead to steel beams, and parts are inconsistent, the cutting edges have relatively deep cuts, the metal sheet edges have significant dents or rather deep zigzag marks, and the cutting is not smooth enough.

Lofting and blanking process

The process belongs to the top part before the parts are processed, and its quality directly affects the following procedure and even causes all the cut parts to be scrapped. This situation is prevalent, so it is essential to strengthening the process’s quality control before cutting. Therefore, we must pay great attention to such issues in construction and inspection.

Steel structure fabrication for painting

The process is also hidden, and the impact on the structure is less than the impact on the building function. It is also a process prone to quality problems. The main quality problems are: the paint film on the surface of the component is partially peeled off in a large area; the paint film on the surface of the component is peeled off; the thickness of the paint film is not enough; the thickness of the paint film is unevenly distributed; the color difference of the paint film is large. The rust removal of steel structural components was sloppy before welding, and the specified level was not achieved. The residues were not cleaned before painting, and there were many wastes, unevenness, and sagging. Failure to remove rust in time will cause the paint to rust and fall off, and the paint layer will be uneven in thickness.

Steel structure fabrication for welding

Steel structure welding is prone to quality problems. In 2004, a company’s product quality report showed that among the quality problems in this process, the reflow rate caused by welding quality was over 80%, followed by the operation errors of the previous cycle and the welding quality problems caused by technical issues of operators. About 10% of the type of problem is the main problem that directly affects the quality of the project. Therefore, this problem requires a professional inspection company to use professional inspection tools for inspection and evaluation. According to the type of defects in the weld, it is divided into slag, undissolved, porosity, etc.

There will be various problems in the processing of steel structures, and our factory has constantly been exploring so that multiple issues do not recur. Based on experience, try to avoid various problems and find the best solution in a time when encountering problems. In addition to the difficulties encountered in the processing process, different issues will occur in the packaging and transportation of steel structural parts before arriving at the site and in the later installation process. Tested on countless projects, our quality is proven. We have been committed to giving customers the most satisfactory results!
