Only look at the appearance of Z steel purlins and the Angle of C steel purlins is different, of which C type is 90 degrees, Z type is less than 90 degrees, about 60-75 degrees. Therefore, when using a purlin on a certain slope of the roof, the Angle of the purlin should be considered. The Z-type makes full use of its flexural properties. If you want to make purlins into connecting members in the process of steel structure processing, compared with C-type steel purlins, you still choose Z-type steel purlins, because the connection of Z-type steel purlins is more convenient. From the point of view of bending, when the slope of the roof is relatively small, the bending section of Z-type steel purlins is slightly larger than that of C-type purlins, but the difference is not particularly large. When the slope of the roof is added, the utilization of Z steel purlins on the vertical zigzag section is added, so Z steel purlins are suitable for roofs with large slope.

Then, from the cross-section point of view, the mechanical properties of C-steel and Z-steel are very different, and the connection with the steel frame is mostly bolts. The calculation needs to be based on the simple support consideration, and the Z-section can be connected by a reliable lap joint and can be calculated according to the connecting beam. Therefore, from the point of view of force conditions, calculation results and structure, Z-type seems more reasonable.

Therefore, in addition to special treatment needs such as door and window holes, CZ steel is still correct. In the entire process of steel structure processing, CZ type steel can be selected as wall purlins and the placement of house purlins with smaller incline. The house purlins placed with a larger slope are suitable for Z-type steel purlins to reduce the roof load through the Z-type purlin section.

Whether it is C-shaped steel or Z-shaped steel, it can be fully utilized as long as it is placed appropriately. Regarding the processing of the entire CZ steel structure components, the two kinds of raw materials required in the steel structure engineering can be processed to meet the standards as long as the original materials are qualified.

CZ steel is commonly used in practical engineering. Commonly used domestic I-steel flange width=100% is narrow, carrying capacity is poor. Compared with H-beam steel of the same type, its cross-sectional area distribution is more reasonable and optimized. H-shaped steel standard table supplied by the manufacturer, the standard is complete. Xiaobian first provides you with the H-shaped steel standard table, and then answers your questions:The good H-shaped steel standard table is here. The next is the difference between welded H-shaped steel and CZ steel:First, welded H-shaped steel. Welding H-shaped steel is to cut the appropriate thickness of the strip into the appropriate width=100%, and weld the side and waist on the continuous welding unit.
