Nowadays, there are many steel structure processing plants and steel structure companies, and the quality of the steel components produced and processed is also uneven. Unqualified steel components will affect the quality and safety of the entire steel structure building. So it is very important to find the right professional manufacturer. So how to judge the processing quality of steel structure parts?
If you encounter poor processing quality of steel structure parts, many problems may occur. Common phenomena include lamellar tearing, overall deformation, joint stress concentration, cracks in welds, and large drilling accuracy errors during thick plate welding, resulting in abnormal installation.
Therefore, it is very important to ensure the processing quality of steel components. For customers who are not familiar with steel structure processing, they may not be able to discern the quality of the components. Then you should pay attention to the following aspects.
1. Find a professional, experienced and qualified steel structure processing factory to Cooperate.
You’d better visit the factory: in addition to the size of the factory, it mainly depends on the quality of the products being processed in the factory and whether the materials are neatly and regularly arranged; whether the equipment is advanced and complete and whether the placement is reasonable; and whether the staffing is complete. Professional and regular factories will be equipped with quality inspectors. The quality inspectors will not only check the material drawings before blanking and cutting, but also solve problems in any process in a timely manner, and check for defective parts after processing. In addition, formal factories have relatively fixed material suppliers, and there are few quality problems with materials.
2. You Can Find A Third-Party Testing Agency For Testing.
If the quality requirements are particularly strict, it is best to find a third-party testing agency to test the steel structure parts. The inspection and identification of steel structures mainly include material and component strength inspection; steel beam and steel column cross-sectional size inspection; steel component weld quality inspection; high-strength bolt torque inspection; steel column verticality inspection; steel beam deflection inspection; steel member anti-corrosion coating thickness inspection ect. as well as joint and joint defects, structural systems, damage detection and safety, serviceability, durability and seismic performance qualification. Third-party testing is more professional, formal and comprehensive.
3. Quality Quality Inspection Needs To Be Carried Out After The Components Arrive At The Site.
Carry out necessary inspections before the components are ready for installation on site. Check whether the packaging of each accessory is complete and reasonable. Check the quantity of components. The components will be numbered. Check the total quantity of components according to the number and place them reasonably. Inspect if any component dimensions, cross-sectional dimensions, or drilling locations can be reviewed according to the drawings. Inspect component connection positions mainly depends on whether there is cracking or corrosion in the welding position. Check the appearance quality of components for paint leakage, scratches, etc.
In conclusion, The quality of steel structure components is related to the quality and safety of the entire building, and every link in it is very important. It is necessary to ensure that there are no problems in every link: the steel material quality is good; the component processing links are standardized; the installation is standardized and professional. Ultimately, the quality and safety of the entire building can be ensured.
