Cast steel node now is widely used in large span space pipe truss of steel structure due to its excellent properties of easy machining and complex various construction forms. It owns the unique advantage, especially in the construction of many complex joint parts. Nowadays, cast node is widely applied in the railway stations, high-speed railway stations airport buildings and stadiums construction., 

Advantages

1. The cast node is made by our particular heat treatment technology which can make its structure optimized and improve its hardness and enhance its wear-proof and anti-impacting properties. 

2. The intersecting body where steel pipes get together is molded directly, it makes the cast node bear more reasonable load, the overall cast node becomes more stable to overcome the harmful impact on overall cast node due to the strong stress caused by a large number of centralized weld.
