There are several different types of space frame structures:

1. Welded Ball Space Frame:
   - Composed of steel balls connected by welded steel tubes.
   - Known for its strength and stability.
   - Widely used in large-scale industrial and commercial buildings.

2. Bolted Ball Space Frame:
   - Utilizes high-strength bolts to connect steel balls.
   - Offers ease of assembly and disassembly, making it suitable for temporary or modular structures.
   - Commonly found in exhibition halls and event venues.

3. Truss Space Frame:
   - Consists of triangular trusses interconnected to form a three-dimensional structure.
   - Provides good load-bearing capacity and rigidity.
   - Often used in bridge construction and long-span roofs.

4. Tube Space Frame:
   - Constructed using steel tubes connected by welding or bolting.
   - Can be designed in various configurations to meet specific architectural and structural requirements.
   - Applied in a wide range of building types, including warehouses and factories.

5. Pyramidal Space Frame:
   - Features a pyramid-like shape with triangular panels.
   - Offers unique aesthetic appeal and can be used for decorative or functional purposes.
   - Seen in some architectural designs and sculptures.

6. Double-Layer Space Frame:
   - Comprises two layers of interconnected members.
   - Provides increased stability and can handle heavier loads.
   - Used in large-span roofs and sports stadiums.
