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

一、Z型钢和C型钢的角度不一样，C型钢成90度而Z型钢小于90度，所以一定坡度的屋面采用檩条时就要结合受力知识考虑檩条的角度问题，坡度大采用Z型钢可以充分利用其的抗弯性能。

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.

二、C型钢截面与Z型钢截面相比，强弱轴的力学性能差异较大，且与钢架的连接多为螺栓铰接，计算时须按简支考虑。故从受力状态，构造以及计算结果等角度看，后者更合理一些。所以除门窗洞口以及其它特殊节点处理需要外，应优先选用Z型钢截面。

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.

三、在屋面坡度较小时，Z型钢檩条抗弯截面模量稍大于C型钢檩条，但差别不大，当屋面坡度增大，Z型檩条对称于竖直方向的抗弯截面模量利用率增大。所以Z型檩条适用于坡度较大的屋面。

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.

四、对于墙面，选择Z型钢或者C型钢没有多大区别，如果檩条想做成连续构件，更好Z型檩条，因其搭接方便。

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.
