Steel Pipe Structure Playground Bleacher Shelter Roofing

The truss structure saves the ball joints of the lower string vertical bar and the spherical grid, and can consider the provisions of various different architectural forms, especially the construction of circular arches and random curves has more advantages than the grid structure. Its directional reliability is the same, saving the use of raw materials. The seamless steel truss structure is based on the basic development trend of the grid structure.  

High stiffness, good geometric characteristics. The wall of the steel pipe is generally thin, and the cross section turning radius is large, so the compression and torsion resistance are good.   

The node form is simple. The structure is simple and smooth, and can be applied to a variety of structural modeling.
