What is the difference between C type steel and Z type steel used in steel structure processing？

Used in steel structure processing of raw materials of steel sheet or direct forming C payments or Z steel, steel for both a lot of people think that in addition to models is no different, especially when we choose materials for wall, both can be used, in fact, there is a difference between these two kinds of steel, then what's the difference between them? Take a look:

Only see appearance, Z section steel purlin and C steel purlin point of view is different, which show 90 degrees C, Z is less than 90 degrees, about 60-75 degrees, so that a certain slope roof using purline is about to consider the combined stress purlin Angle problem, large slope using Z can make full use of its bending performance. If you want to make continuous member purlins in steel structure processing, then relative to C type steel purlins or CHOOSE Z type steel purlins, this is because Z type steel purlins lap more convenient.

To look from the flex resistance, at the time of roof slope is small, Z section steel purlin bending section modulus slightly greater than the C purline, but the difference is not huge, when the roof slope increase, Z section steel purlin for vertical bending section modulus increases the utilization rate of, so Z steel purlin is suitable for the steep roof.

And then from the point of view of cross section, C payments and Z axis on the strength of the steel mechanics performance difference is bigger, and steel connection for bolt connection, at the time of calculation, it is necessary to take into account the simply supported and Z section can be achieved by reliable lap between steel knot, so that we can according to the continuous beam calculation, so from a state of stress, the calculation results and the Angle of the structure, The Z-type seems more reasonable. So the treatment of doors and Windows and other special processing needs, the priority is still Z steel. The whole steel structure in the process of processing wall purlin and use the slope is not large house purlin can choose TO use C type steel, use the greater slope of the house purlin suitable for the use of Z type steel purlin, so that the roof load force through the Z type purlin cross-section is reduced.

Both C-shaped steel and Z-shaped steel can be fully used as long as it is placed in the right position. For the processing of the whole steel structure components, the two kinds of steel structure engineering are the raw materials needed, and as long as the raw materials are qualified, they can be processed to meet the standard components.
