Two Main Node Systems about Steel Space Frame
1. Bolted spherical node (Mero-type): steel tubes converge at a machined sphere, connected by high-strength bolts. Fast fabrication, easy on-site assembly, ideal for regular grids — most popular for roofs and canopies.

2. Welded hollow ball / plate node: higher stiffness for heavy or irregular loading, common in industrial and complex geometric projects.

3. Special systems: pipe truss (spatial tubular truss), cable dome and string-beam hybrid systems for super-spans.
