OEM China Lightweight Steel Roof Trusses - Large Span Steel Truss Stadium Bleacher – HJZC

Advantages of truss structure

1. Node form and structure is simple and smooth, and can be applied to various structural shapes. 2. High rigidity and good geometric characteristics. Generally, the wall of steel pipe is thin and the radius of gyration of section is large, so it has good compressive and torsional properties. 3. Simple construction, saving materials. Truss structure has the advantages of simple construction and material saving, because the traditional connecting members are abandoned at the joints and the members are directly welded. 4. It is beneficial to rust prevention and cleaning maintenance. The steel pipe has a small contact surface area with the atmosphere, so it is easy to protect. Each bar is directly welded at the node, and there are no dead corners and grooves that are difficult to clean, paint, accumulate moisture and a lot of dust, so it is more convenient to maintain. After the whole length and end of the tubular member are closed, the inside of the tubular member is not easy to rust. 5.The tube truss structure with circular tube section has good hydrodynamic characteristics. When subjected to loads such as wind or water flow, the effect of load on circular tube structure is much lower than that of other cross-section structures.
