The raw materials used in steel structure processing are steel plates or directly formed C-section steel and Z-section steel. Many people think that there is no difference between these two steels except for the model. Especially when we choose materials for the wall, these two steels can be used. In fact, these two steels are different. So what is the difference between them? Let's follow Jinan C-section steel manufacturers to understand.
Just looking at the appearance, the angles of Z-shaped steel purlins and C-shaped steel purlins are different. Among them, C-shaped purlins are 90 degrees, while Z-shaped purlins are less than 90 degrees, which is about 60-75 degrees. Therefore, when purlins are used for roofs with a certain slope, the angle of purlins should be considered in combination with the stress. Z-shaped purlins with a large slope can make full use of their bending resistance.
If you want to make purlins into continuous members in the process of steel structure processing, you should choose Z-shaped steel purlins over C-shaped steel purlins, because the overlapping of Z-shaped steel purlins is more convenient.
From the perspective of bending resistance, when the roof slope is relatively small, the bending section of Z-shaped steel purlins is slightly larger than that of C-shaped purlins, but the difference is not particularly large. When the roof slope is large, the utilization rate of Z-shaped steel purlins for the vertical bending section is large, so Z-shaped steel purlins are suitable for roofs with large slopes.
Then, from the cross-section, the mechanical properties of the strong and weak axes of C-section steel and Z-section steel are quite different, and the connection with the steel frame is mostly bolt connection, which needs to be considered as simple support in the calculation, while the connection between Z-section can be realized by reliable overlapping, so it can be calculated as a continuous beam.
Therefore, from the point of view of stress state, calculation results and structure, Z-type seems more reasonable. Therefore, in addition to processing door and window openings and other special processing needs, Z-shaped steel is still preferred.
In the whole process of steel structure processing, wall purlins and roof purlins with small shelving slope can use C-shaped steel, and roof purlins with large shelving slope can use Z-shaped steel purlins, so that the roof load can be reduced through the section of Z-shaped purlins.
In a word, both C-shaped steel and Z-shaped steel can be fully utilized as long as they are placed in the right position. For the processing of the whole steel structure components, these two kinds of raw materials are needed in the steel structure project. As long as the raw materials are qualified, the components that meet the standards can be processed. For more information, please visit our website http://www.jnhscg.com Consult!
