佰富彩Just looking at the appearance, the angles of Z-shaped steel purlins and C-shaped steel purlins are different. The C-shaped purlins are at 90 degrees, while the Z-shaped ones are less than 90 degrees, which is about 60-75 degrees. Therefore, when using purlins on roofs with a certain slope, the angle of the purlins should be considered in conjunction with the force. Using Z-shaped purlins with a large slope can fully utilize their bending performance. If you want to make purlins into continuous components in the processing of steel structures, then compared to C-shaped steel purlins, Z-shaped steel purlins are still preferred because the overlapping of Z-shaped steel purlins is more convenient.
When the roof slope is relatively small, the bending section of Z-shaped steel purlins is slightly larger than that of Jinan C-shaped steel purlins, but the difference is not particularly significant. When the roof slope increases, the utilization rate of Z-shaped steel purlins for the vertical bending section increases, so Z-shaped steel purlins are suitable for roofs with large slopes.
佰富彩The mechanical properties of the strong and weak axes of C-shaped steel and Z-shaped steel differ greatly, and the connection with the steel frame is mostly bolted. When calculating, it needs to be considered as simply supported, while the connection between Z-shaped sections can be achieved through reliable overlap, which can be calculated as a continuous beam. Therefore, from the perspective of stress state, calculation results, and construction, Z-shaped steel seems more reasonable.
So, in addition to handling door and window openings and other special treatment needs, Z-shaped steel is still the preferred choice. During the entire steel structure processing process, C-shaped steel can be selected for wall purlins and roof purlins with small shelving slopes. Z-shaped steel purlins are suitable for roof purlins with larger shelving slopes, so that the roof load force is reduced through the cross-section of Z-shaped purlins.
佰富彩Both C-shaped steel and Z-shaped steel can be fully utilized as long as they are placed in the proper position. For the processing of the entire steel structure component, both of them are required raw materials in the steel structural engineering. As long as the raw materials are qualified, the components that meet the standards can be processed. For more related matters, come to our website http://0082tv.com consulting service
