With the increasing popularity of steel structures, the use of C-shaped steels and z-shaped steels has also increased. What is the difference between the two? Here, Xinjiang Qijia gives everyone the emphasis on the differences between c-steel and z-steel:
1. The angles of Z-shaped steel and C-shaped steel are different. The C-shaped steel is 90 degrees and the Z-shaped steel is less than 90 degrees. Therefore, when using a screed on a certain slope, it is necessary to consider the angle of the purlin in combination with the knowledge of the rake, and the slope is large and the Z-shaped steel can be used. Take full advantage of its bending performance.
2. Compared with the Z section, the mechanical properties of the C-section and the Z-section are different, and the connection to the steel frame is mostly bolted. The calculation must be based on simple considerations. Therefore, from the aspects of stress state, structure and calculation results, the latter is more reasonable. Therefore, in addition to door and window openings and other special node processing needs, Z-sections should be preferred.
Third, when the roof slope is small, the modulus of bending section of Z-section steel beams is slightly larger than that of C-section steel beams, but the difference is not significant. When the roof slope increases, the modulus of use of the bending section of Z-type beams symmetrically in the vertical direction increases. Big. Therefore, Z-type purlins are suitable for roofs with large slopes.
Fourth, for the wall, the choice of Z-beam or C-beam does not make much difference, if the purlins want to make a continuous component, the best Z-type purlins, because of its convenient lap.
