At present, the use of building materials is very extensive, and the use of steel is essential in the construction process. However, there are many types of steel, and what are the connections and differences between them? Here, the editor will introduce the difference between c-shaped steel and Z-shaped steel:
1. The angles of Z-shaped steel and C-shaped steel are different. The angle of Z-shaped steel is 90 degrees, while the angle of Z-shaped steel is less than 90 degrees. Therefore, when using a roof with a certain slope, the angle of the purlins should be considered in conjunction with the knowledge of stress. When the slope is large, the bending performance of Z-shaped steel can be fully utilized.
2. Compared with the Z-shaped section, the C-shaped section steel has a significant difference in the strength and strength of the axial force performance. The connection to the steel frame is mostly bolted, and simple support should be considered in the calculation. Therefore, from the perspective of stress state, structure, and calculation results, the latter is more reasonable. Therefore, in addition to the processing needs of special nodes such as doors and windows, Z-shaped steel should be preferred.
When the roof slope is small, the bending section modulus of Z-shaped purlins is slightly higher than that of C-shaped purlins, but the difference is not significant. When the slope of the roof increases, the utilization rate of the bending section modulus of the symmetrical vertical Z-shaped purlins increases, so Z-shaped purlins are suitable for roofs with larger slopes.
For walls, there is not much difference between choosing Z-shaped steel or C-shaped steel. If purlins are to be made into continuous components, it is best to use Z-shaped purlins because they are easy to overlap.
