What is S690QL equivalent material equivalent steel in GB standard

The selection principle of steel plate for high-rise building is: it can not only make the structure safe and reliable, but also can save steel and reduce the cost. Different use conditions should have different quality requirements. In terms of the mechanical properties of steel such as S690QL equivalent material, yield point, tensile strength, elongation, cold bending property, impact toughness etc. are the indicators to measure the quality of steel. In the design of steel structure, the appropriate steel should be selected according to the characteristics of the structure. The selection of steel is not only an economic problem, but also related to the safety and service life of the structure.

The advantages of S690QL equivalent material, medium and thick boiling steel plate: The surface is relatively smooth, the quality is good, and it is easy to process. Because medium and thick boiling steel plate does not have concentrated shrinkage holes, the amount of deoxidizer is small, and boiling steel plate price is lower than other steel plates. Disadvantages of medium and thick boiling steel plate: it has a lot of gas content and impurities, it is not easy to weld, and its bearing capacity is worse than other steel plates, so it is not suitable for parts that need to bear gravity.

When talking about our team, it is hard not to mention our QC department (Quality Control). We have built strict qualitycontrol system to guarantee the steel quality. During the steel materials production, we have strict monitoring measures and indicators, and ensure no chemical composition, mechnical properties and so on technical problems for the steel materials S690QL equivalent material. After production, our QC department will conduct another inspection regarding to the steel quantity, dimension, mark and so on points before delivery.
