According to the supporting structure, it is divided into eight categories:

1. Steel structure supporting type:

2. Rib connecting support type;

3. Rod support type:

4. Cable supporting type:

5. Single cable support type;

6. Self-balancing support type;

7. Tension beam supporting type;

8. Combined structure support type

1. Steel structure supporting type:

(1) Single beam structure:

A. Pipes-square pipe, rectangular pipe, round pipe;

B. Profiles-I-beam, channel steel, T-beam, variable cross-section beam (Mei Chemical steel), steel plate;

(2) Truss structure:

A. Double-column truss (plane truss)-parallel chord truss;

B. Double-column truss (plane truss)-fish belly truss;

C. Multi-column truss-triangular truss/four-column truss (also known as cage truss);

(3) Grid structure:

A. Welded grid;

B. Screw-on grid.
