At present, the use of building materials is very extensive. In the construction process, the use of steel is essential. However, there are many kinds of steel. What are the connections and differences between them? Here, Jinan C-section steel plant introduces the difference between C-shaped steel and Z-shaped steel
1、 The angle of Z-shaped steel is different from that of C-shaped steel. C-shaped steel is 90 degrees, while Z-shaped steel is less than 90 degrees. Therefore, when purlin is used for a certain slope roof, the angle of purlin shall be considered in combination with the stress knowledge. The bending resistance of Z-shaped steel can be fully utilized when it is used for a large slope.
2、 Compared with Z-section, the mechanical properties of the strong and weak axes of the C-section are different from those of the Z-section, and the connection between the C-section and the Z-section is mostly hinged by bolts. Therefore, the latter is more reasonable in terms of stress state, structure and calculation results. Therefore, in addition to the needs of door and window openings and other special joints, Z-section should be preferred.
3、 When the roof slope is small, the bending section modulus of Z-shaped purlin is slightly higher than that of C-shaped steel purlin, but the difference is not significant. When the roof slope increases, the utilization ratio of Z-shaped purlin's bending section modulus symmetrical to the vertical direction increases. Therefore, z-purlin is suitable for roof with large slope.
4、 For the wall, there is no big difference between the selection of Z-shaped steel or C-shaped steel. If the purlin wants to be made into continuous members, it is better to use Z-shaped purlin because of its convenient overlapping.
The above is the introduction of relevant knowledge about C-section steel, hoping to help you. For more information, please continue to follow our website More wonderful content will be presented later.
