What's the difference between grid steel frame and section steel frame? What conditions do you adapt to?

1. The steel frame has good rigidity and can bear the load after erection; After the grid steel frame is erected, concrete is sprayed until the concrete reaches a certain strength to bear the load, which has different timeliness.

2. Under the same stress, the cost of steel frame is higher than that of grid structure.

3. Steel frame needs mechanical bending, which is more difficult to process than grid frame.

4. The gap between steel frame and surrounding rock is easy to leak concrete.
