I. Preparatory Phase 

Design integration and technical review 

The technical team of the organization coordinated with the design institute to review the steel structure drawings. 

The key point is to inspect the connection nodes between the embedded parts and the main structure. 

Confirm the load requirements (especially the special vibration loads in the railway sector) 

2. Material Procurement and Inspection 

Select common railway steel materials such as Q355B or Q235B. 

Purchase the corresponding high-strength bolts (8.8 grade or 10.9 grade) 

After the materials are delivered, strict re-inspections for mechanical properties and ultrasonic testing are carried out. 

II. Production and Manufacturing Phase 

Cutting and processing of materials 

Carry out precise cutting using a CNC cutting machine 

The ends of the string rods and web rods are machined flat according to the design. 

The embedded steel plates undergo drilling and surface treatment. 

2. Specialized fabrication of embedded parts 

Manufacture shear keys and anchoring bars in accordance with railway standards 

The surface of the embedded parts is sandblasted for rust removal (to a Sa2.5 level) 

The embedded parts are treated with hot-dip galvanizing for corrosion prevention (with a thickness of ≥ 80 μm)
